Mattresses in a box have made it easier than ever for sleepers to find a bed just right for your sleep style. Boxed beds have been flattened and rolled but once they’re out of the packaging, they’re virtually indistinguishable from traditional mattresses.
Many of the best mattresses we’ve tested have been beds in a box, and while they share a convenient packing method, these mattresses are diverse. Encompassing everything from affordable hybrids to luxury memory foams and organic latex mattresses, beds in a box rival traditional mattresses when it comes to support, comfort and variety. And in the regular mattress sales, there’s a mattress in a box for every budget (as well as every sleep style.)
1. The best mattress in a box overall
Quick summary
The DreamCloud is more than just the best mattress-in-a-box overall – we also rank it as one of this year's best hybrid mattresses too. It offers excellent hip and back support which should provide relief for those with back pain. Most body types and sleep positions will feel supported on this affordable hybrid, although some side sleepers (and especially those under 130lbs) might find it a bit too firm, even after an initial break-in period. If that's you, consider spending a little more for the Helix Midnight Luxe (#4), or go with the affordable all-foam Nectar Classic (#2).
One of our favorite things about the DreamCloud is the value for money it offers. An evergreen DreamCloud sales places it in the lower mid-range price bracket and the benefits are premium: a 365-night trial and lifetime warranty. Only the Nectar Classic in this guide offers comparable extras (although the Bear Hybrid Elite at #7 has a lifetime warranty.)

The DreamCloud mattress doesn't sacrifice value for quality. It's our favorite mattress in a box because it combines the budget-friendly pricing we expect of a boxed bed with a versatile, supportive sleep feel.
Our review: in more detail
At the top of the DreamCloud Hybrid you'll find thick layers of foam, which contour comfortably around your joints and relieve pressure. Beneath these is a tier of 8" wrapped springs that amp up the support and create space for air to circulate within the mattress. (We think the DreamCloud mattress regulates temperature well, too, although not as well as the Bear at #7.)
Our panel of volunteers – who deal with everything from lower back pain to the occasional "dead hip" – indulged in this balanced bed feel and experienced diminished pain in those areas. We slept on a previous-gen DreamCloud in a twin size for three weeks, rating it 8 out of 10 on the mattress firmness scale. That is firmer feel is ideal for back and stomach sleepers, but it took a while for our side sleeping testers to get comfortable. Side sleepers with a lighter build should consider the Helix Midnight Luxe (#4) or the Nectar Classic (#2.)
I often recommend the DreamCloud for those who want a hotel-quality look and feel
If you share a bed, the DreamCloud's high level of motion isolation will allow you and your sleeping partner to enjoy peaceful nights together. The edge support of the previous DreamCloud model was lacking in our experience, but the updated design we're currently reviewing features firmer coils along the perimeter to address that flaw.
I often recommend the DreamCloud for those who want the hotel-quality look and feel of our number one-rated mattress overall, the Saatva Classic mattress, at a lower price point. Our testers were impressed by the DreamCloud's excellent build quality, and some long-time DreamCloud customers claim to still sleep comfortably on their bed years after purchase.
What we like about it...
Why you can trust Tom's Guide Our writers and editors spend hours analyzing and reviewing products, services, and apps to help find what's best for you. Find out more about how we test, analyze, and rate.
✅ A 5-star mattress at a 3-star price: Don't let the DreamCloud's boxed bed status and mid-range price fool you. I often recommend it as an alternative to the Saatva Classic if you want a luxury bed on a budget.
✅ Soothes for back and hip pain: The DreamCloud's combo of adaptive foam and wrapped innersprings relieves pressure from your lower back and hips whilst promoting proper spinal alignment, resulting in diminished pain in those areas.
✅ Fantastic for bed sharers: The DreamCloud does an exceptional job of diminishing most movements so you and your partner can peacefully share a bed. The improved edge support will also make bed-sharing easier.
What we don't like about it
❌ Too firm for lighter side sleepers: The DreamCloud has a firmer feel than advertised, and lightweight side sleepers are likely to wake up with a numb arm. The Helix Midnight Luxe (#4) has a similar build with softer cushioning.
❌ There's limited sink: Though the DreamCloud has upper foam layers, you won't experience the deep pressure relief you would with a Nectar (#2) or Purple (#6). This is a mattress you lie on top of.
❌ It takes some time to break in: Your first night on the DreamCloud might not be as comfortable as you were expecting, as this mattress needs to be broken in (especially for side sleeping.) The Leesa Sapira (#9) is comfortable for side sleepers right from the get-go.
Features | In brief | Score |
|---|---|---|
Support and comfort | Suits back and stomach sleeping best; side sleepers may need to be patient with breaking it in. | ★★★★½ |
Pressure relief | A more subtle hug, our testers found immediate relief in their lower back and hips. | ★★★★½ |
Temperature | Cashmere-blend cover wicks moisture while the pocket coils help with airflow. We didn't overheat. | ★★★★½ |
Motion isolation | Performed well in our drop tests, as we observed minimal transfer of movement across the surface. | ★★★★ |
Edge support | Originally lacking in this area, but the redesign with firmer perimeter coils will likely boost this score. Stay tuned. | ★★★½ |
Build quality | Our testers found it sturdy and luxurious, and long-time DreamCloud customers say it holds up well. | ★★★★½ |
When, where and how to buy
As a rule, hybrids tend to cost more than all-foam mattresses, especially luxe-feeling ones like the DreamCloud, but this mattress consistently comes in at a mid to lower mid-range price, depending on when you buy. It stands out for undercutting most of the competition and delivering excellent value for money.
The DreamCloud mattress sale is evergreen, so you can ignore the Total Value pricing (DreamCloud's alternative to the MSRP.) A twin will typically cost you $449, a queen $665 and a king $835.
Because it's from the same parent company as the Nectar (also on this list), it comes with the same outstanding extras. You'll have a year to try it out before fully committing, and it's backed by a Forever warranty.
DreamCloud mattresses are also sold on third-party sites, including the DreamCloud Amazon store. While the prices here tend to echo the brand's prices, you can sometimes spot good deals on older models.
The DreamCloud Mattress delivers an excellent performance from a lower price bracket. It's supportive for back and stomach sleepers, with the cushioned surface offering relief from aches and pains. Side sleepers can also get comfortable on the DreamCloud, although it might take a few weeks to break in — but you have 365 nights to test the bed at home, so that's ample time to adjust.

2. The best memory foam mattress in a box
Quick summary
Nectar is a popular mattress in a box brand and its flagship Nectar Classic Memory Foam is an excellent value bed in a box. The balanced foam feel is ideal for side and back sleepers, but stomach sleepers should consider a firmer mattress such as the Siena (#3). Our testers rated it highly for motion isolation and were impressed by the top cover's moisture-wicking properties.
The Nectar is a medium-firm mattress that leans towards firm, but we found it delivered an excellent balance of softness and support. You ease into the upper foam layer which comfortably cushions the joints, but the dense foams beneath prevent you from sinking too far. While not as marshmallow-y as the Leesa Sapira (#9), this is a good middle ground for most sleepers.
Read what we liked, didn't like, and how to buy it ▼
Nectar's popular five-layer all-foam mattress hits that sweet spot between value and performance. In short, you're getting a superbly comfortable and good-quality mattress for an extremely reasonable price.
Our review: in more detail
We tested this 12" tall, all-foam mattress for two months and loved it. The firmer (we rated it 7.5 out of 10) memory foam offers a fantastic balance of softness and firmness, providing luxury comfort without the feeling of sinking into the mattress. When our reviewers laid down, the mattress contoured to their bodies, providing full, tailored support and helping align their spines, while cushioning pressure points like shoulders and hips.
The high-density foam core provides impressive support, ensuring our testers didn't sink too far into those comfort foams. But it may be a different story for sleepers over 230lbs or those who like to rest on their front. Upgrading to the Nectar Classic Hybrid could help with this; the DreamCloud at the top of our list is also a great choice for sleepers who could benefit from a firmer level of support.
When it comes to sheer value for money, the Nectar is the best memory foam mattress you can buy
The Nectar has decent edge support (for a memory foam) although it can't compare to the all-foam Plank Firm (#5). And there's very little motion transfer, making it a particularly good choice for couples. The quilted cooling cover prevented us from waking up in a sweat, but for chronically hot sleepers, we're inclined to recommend a specialty cooling mattress like the Bear (#7) or the similarly-priced Cocoon Chill (#8).
When it comes to sheer value for money, I think the Nectar is the best memory foam mattress you can buy. Nectar is often compared to Tempur-Pedic, as both brands are known for the body-hugging comfort of their foams. However, Tempur-Pedic mattresses are a splurge, while the Nectar is a bargain for those who want a similar level of cushioned pressure relief without overspending. Nectar is much more generous with its warranty and trial periods than Tempur-Pedic, too.
What we like about it...
✅ A Tempur-like mattress for less: The Nectar isn't the cheapest mattress on this list (that would be its sibling, the Siena, at #3), but at a lower mid-range price point it's an incredible value, especially once you factor in the extras.
✅ A truly balanced bed feel: With a firmness rating between 6.5 and 7 (out of 10), the medium-firm Nectar will appeal to many side and back sleepers who want to comfortably sink into their mattress without sacrificing support.
✅ A dream for couples: Whether you bed share with your partner, kids, or pets, the Nectar's superb motion isolation will leave you largely unbothered by their movements (and vice versa). Plus, the medium-firm feel suits a range of sleep styles.
What we don't like about it
❌ It can sleep warm: While the Nectar sleeps cooler than expected for a full-foam bed, a specialty cooling model like the similarly-priced Cocoon Chill (#8) or the premium Bear (#7) will be a better fit if night sweats keep you up at night.
❌ Less support for heavy people: The Nectar may not provide enough support for heavier bodies. Consider a sturdier hybrid like the DreamCloud (#1), especially if you sleep on your back or front.
❌ Average edge support: Memory foam mattresses often struggle with edge support, but while the Nectar's weaker sides aren't unusual, it might be an issue if you have limited mobility. The Siena (#3) and Plank (#5) are all-foam beds with sturdier perimeters.
Features | In brief | Score |
|---|---|---|
Support and comfort | On the firmer side of medium, with plenty of support and enough contouring for most side and back sleepers. | ★★★★½ |
Pressure relief | Akin to Tempur-Pedic, with ample cushioning for shoulders and hips | ★★★★½ |
Temperature | Surprisingly comfortable for an all-foam bed (we didn't sleep warm), but there are cooler options still. | ★★★★ |
Motion isolation | Among the best mattresses we've tested, as the Nectar does a stellar job of preventing movement from traveling across the surface. | ★★★★½ |
Edge support | Memory foam mattresses aren't usually known for steady edges, although the Nectar's edge support is passable. | ★★★½ |
Build quality | Made well relative to cost, but for best results, allow it to fully expand once you unbox it. Beware that it could take up to 48 hours. | ★★★★ |
When, where and how to buy
You can ignore the MSRP (or Total Value) at Nectar, because these beds are never sold at full price. A queen will typically set you back around $649 during the evergreen Nectar mattress sale. That's considerably cheaper than rivals Casper, Purple and Tempur-Pedic. Add to that a generous one-year trial period to decide whether it's right for you and a lifetime warranty to back up your purchase.
Nectar's sale prices rarely change, even over the major holidays, so we think it's always a good time to buy. The occasional flash sale might net you a discount but these are hard to predict and rarely include queen sizes.
We have sometimes spotted some good deals from third-party retailers, including the Nectar Amazon store. But for the most part, you'll find consistent pricing on the Nectar Classic.
It might be firmer than our testing team were expecting, but the Nectar Classic still has contoured pressure relief that will cradle side sleepers and prevent the dreaded numb arm. I'd also recommend the Nectar Classic for back sleepers, although stomach sleepers should look for a mattress with more support at the hips.

3. The best cheap mattress in a box
Quick summary
The Siena Mattress is the cheapest bed-in-a-box on our list, but performance-wise it holds its own among its higher-priced rivals – including its older sibling, the Nectar, which sits directly above it on this list.
Back and stomach sleepers will enjoy its outstanding support and subtle contouring, while couples and families will appreciate the low level of motion transfer. Side sleepers should look for something softer (like the Nectar), but with decent temperature regulation and strong edge support, the Siena is an impressive all-rounder. At this price, we strongly recommend it for a guest bed or a college dorm.

The Siena Memory Foam Mattress is proof that you don't have to shell out a lot of money for a quality mattress.
Our review: in more detail
When we called the Siena Mattress in for testing, we weren't expecting much. After all, how good can a cheap mattress in a box really be? Very good, is the answer, if it's made by the parent company behind Nectar and DreamCloud, both featured in this guide. Our lead tester was very impressed by how well-made it is considering the cheaper price – a queen regularly goes for $399.
I recommend the Siena Mattress for stomach and back sleepers – it's much firmer than Siena Sleep's rating of 6.5 out of 10 on the firmness scale; we rate it as a 9. That firmness ensures that you'll sleep on top of the mattress in both positions, which prevents your back and spine from dipping out of alignment and causing you lower back pain.
How good can a cheap mattress in a box really be? Very good, is the answer
Of course, that does lead us to recommend side sleepers look elsewhere in this guide (like the Siena's cousin, the Nectar.) The firmness does lend sturdy edge support to the Siena Memory Foam Mattress in a box, meaning you can sleep right up to the edge of your bed to maximize space. You shouldn't have any issues getting in and out of bed, or when sitting on the edge to get dressed.
We were also surprised by how cool the Siena slept, which is unusual for a budget all-foam box bed. However, that could be because you don't sink into the surface, limiting the foam's ability to emit our body heat right back at us. For very hot sleepers, the Cocoon (#8) has better cooling and a similar firm feel. But you'd struggle to improve the motion isolation: the dense Siena memory foams absorb all but the most vigorous of movement.
What we like about it...
✅ It's budget-friendly: At under $500 for the largest size (king), the Siena is a bonafide budget buy if you're not willing or able to splash out the cash for something else – especially if this is meant for temporary or irregular use.
✅ There's little sink for stomach and back sleepers: Granted, there's a break-in period involved, but even after a month of sleeping on the Siena mattress in a box our testers still considered it much firmer than expected with minimal give. Back and stomach sleepers will enjoy this.
✅ Top-notch motion isolation: The all-foam Siena absorbs most movement with ease. Consider this one if you share a bed with a fidgety partner or someone who operates on a different schedule than you do.
What we don't like about it
❌ Lacks deep pressure relief: The Siena's pressure relief is subtle, but that may not be enough for side sleepers or those who need extra cushioning to alleviate back and joint pain. The Nectar (#2) is a softer lower-cost foam mattress.
❌ Not suitable for very hot sleepers: Since we felt like we were sleeping on top of the Siena rather than in it, we hardly broke a sweat. Still, this is an all-foam mattress and won't be as breathable as a hybrid or a specialty cooling model like the Cocoon (#8.)
❌ Questionable durability: While we rated it well on initial durability, it may not have the lasting power of a hybrid like the DreamCloud (#1), which also boasts a lifetime warranty. You'll get 10 years of coverage with the Siena.
Features | In brief | Score |
|---|---|---|
Support and comfort | Our testers found it firmer than advertised, but if you're a back or stomach sleeper, you won't mind this. | ★★★★ |
Pressure relief | Minimal give, which will be a detriment to lighter sleepers and strict side sleepers. | ★★★½ |
Temperature | Despite testing it in the summer, our testers didn't sleep warm on the Siena, but we think the lack of sinkage is a big reason why. | ★★★★ |
Motion isolation | On par with the Nectar as an all-foam bed that doesn't let much movement go beyond the source. | ★★★★½ |
Edge support | The Siena exceeded our expectations here, as we had no issue sitting on the sides of the bed. | ★★★★ |
Build quality | The jury is out on long-term durability, but our testers said it looks and feels more expensive than it actually is. | ★★★★ |
When, where and how to buy
The Siena is excellent value for money and a great cheap bed in a box from a trusted name. It's perpetually discounted and the Siena mattress sales rarely change. Still, at $399 for a queen-sized mattress after discount, we're not complaining. The 180-night trial is also remarkable for this price point, while the 10-year warranty is standard, but still decent.
For the most part, Siena keeps the sale year-round. However, we have spotted some better discounts in recent months, with Black Friday 2024 reducing a queen to $379 direct from Siena — and even cheaper on the Siena Amazon store.
I wasn't expecting much from the Siena Memory Foam Mattress — at less than $400 for a queen, it's a real budget buy. But the Siena bed in a box impressed me with its full-body support and light cushioning. As a stomach sleeper, I'd happily drift off on it. Cheaper all-foam beds tend to have a lot of sag, something the Siena avoids thanks to its firm feel. On the flipside, there's just not enough pressure relief for side sleepers.

4. The best mattress in a box for side sleepers
Quick summary
The Helix Midnight Luxe is our favorite mattress for side sleepers with a plush pillow-top and enhanced lumbar support – elements that translate to a comfy sleep experience for back sleepers, too. As the middle child in the 3-model Helix Midnight lineup, it possesses the best mix of performance, luxury and overall value (but if you're on a tighter budget, the Helix Midnight Core is equally supportive, if not as luxuriously plush.)
As a hybrid, it doesn't provide the profound sink-in sensation of a full-foam bed. if that's what you're after, consider the Nectar at #2. But the Midnight Luxe has upper memory foam layers to offer gentle contouring along the shoulders, hips and knees – key pressure points that affect side sleepers most. The Midnight Luxe also stands out for its minimal motion transfer, making it a good choice for couples and families.
Read what we liked, didn't like, and how to buy it ▼
Designed and crafted for side sleepers, we feel the Helix Midnight Luxe Mattress hits the brief — and proves you can get luxury in a box.
Our review: in more detail
Our lead tester slept on a queen-size Helix Midnight Luxe for seven weeks. Helix rates it a 5-6 (out of 10) on the firmness scale. We think it's a solid 6 out of 10 — a true medium mattress.
The Midnight Luxe's premium pillow-top and ultra-responsive memory foam layers yield incredible pressure relief, while the steel coils (reinforced in the center for alignment) prevent sleepers from sinking too deep. Our lead tester avoided the 'dead hip' she's prone to developing when resting on her side for too long, and her heavier back-sleeping partner also felt comfortable and supported. Combined with top-notch motion isolation, it's an excellent choice for couples with diverse sleep needs (but the Leesa Sapira at #9 might come out on top for two side sleeping bed sharers.)
The premium pillow-top and ultra-responsive memory foam layers yield incredible pressure relief
Although our testers didn't overheat on this mattress, hot sleepers may want to consider an upgrade to the GlacioTex cooling Pillow Top cover for an extra $199 across all mattress sizes. This specialty material is cool to the touch but yields a slick surface that could make dressing your bed a hassle. The Bear Elite in Soft (#7) is another alternative.
There's also an optional ErgoAlign layer ($199) for even more lumbar support, which another one of our testers had the chance to try while visiting 3Z Brands in Arizona (she was a fan). As with the DreamCloud, edge support is passable here – but if edge support is a priority for you due to mobility issues, I recommend the Plank Firm (#5) as a mattress that excels in that area.
What we like about it...
✅ Crafted for dedicated side sleepers: A plush pillow-top and multiple comfort foam layers provide plenty of pressure relief, and the reinforced springs in the middle of the bed keep everything properly aligned.
✅ But comfortable for back sleepers: Like to flip-flop between your side and your back? No problem. The Midnight Luxe's medium-firm bed feel will keep you supported, either way. It also makes bed sharing a fair bit easier.
✅ Eats up movement: Restless partner? Overzealous pet? The Helix Midnight Luxe dampens movement so well, you'll feel like you're sleeping solo.
What we don't like about it
❌ Too plush for stomach sleepers: This side sleeper mattress is back sleeper-friendly, but stomach sleepers won't find it firm enough for their tastes. Side sleepers should check out the Plank Firm (#5) and Helix Dusk Luxe instead.
❌ Middling edge support: The edge support isn't bad here, but we wouldn't call it amazing, either. We think the pillow-top hinders this bed's ability to offer a sturdy perimeter you can confidently sit on, unlike the flat surface of the supportive Plank Firm.
❌ Cheaper alternatives: The Helix Midnight Luxe is a premium mattress, even when it's on sale. The Helix Midnight from the Core range offers similar support for side sleepers, although you'll miss out on the plush pillowtop.
Features | In brief | Score |
|---|---|---|
Support and comfort | Well-balanced for side and back sleeping, with the plush pillow-top adding sink-in softness. | ★★★★ |
Pressure relief | In our experience, no other mattress cushions the shoulders, hips, and knees best whilst side sleeping. | ★★★★½ |
Temperature | The included Tencel cover kept our testers comfy and dry – consider the GlacioTex upgrade if you sleep very hot, though. | ★★★★ |
Motion isolation | In our objective and real-world tests, the Midnight Luxe did an outstanding job of limiting movement. | ★★★★½ |
Edge support | We could comfortably sit on the sides and sleep up against the edge without fear of falling over. | ★★★★ |
Build quality | A durable, beautifully-made mattress that wouldn't look out of place in a luxury hotel. | ★★★★½ |
When, where and how to buy
Regular Helix mattress sales cut between 20% and 25% off, but we've seen as much as 30% off around major holidays. Still, you'll never have to worry about buying this mattress at the list price. A queen has an MSRP of $2,373 but you'll never pay that much — we see it on sale for $1,899 all the time. If you aren't in a rush to buy, it's worth waiting for the 25% discount to kick in, as it comes round several times a year.
You have 100 nights to test it out. Better yet, Helix Luxe mattresses come with a 15-year warranty (versus 10 years for the Classic models). You'll often be able to score a pair of free pillows or a bedding set with purchase, too.
I've listened to multiple side sleeping team members rave about the Helix Midnight Luxe Mattress, praising the luxuriously plushness and balanced feel. With cooling and supportive upgrades available, this mattress can suit a lot of sleepers. But not if you lie o your stomach — try the Helix Dusk Luxe instead.

5. The best firm mattress in a box
Quick summary
If you're looking for the best firm mattress, then they don't come much firmer than this. The Plank Firm Mattress is a double-sided all-foam design (one side is Firm, the other Extra-Firm.) We rated it an eight and nine out of 10, respectively, on the firmness scale, with a lack of sink that means you really lie on top of this mattress.
The upside of this incredibly firm feel is that the Plank offers exceptional support, from head to toe, edge to edge and corner to corner. For stomach sleepers, this ensures the hips are held comfortably aligned with the spine, while back sleepers who prefer a firmer feel will appreciate how it lifts the lower back (for back sleepers who prefer some cushioning, try the Siena at #2.) The lack of sink does mean pressure relief is minimal, with no cushioning for side sleepers.
Read what we liked, didn't like, and how to buy it ▼
The Plank Firm isn't what you'd expect from a memory foam mattress in a box, but it's super-firm results in a super-supportive feel across the body.
Our review: in more detail
We slept on a full size Plank Firm Mattress for over a month, spending more than three weeks on the Extra Firm side and three weeks on the Firm side. At the end of the testing period our panel agreed the Firm side feels like 8 (out of 10) on the firmness scale, while the Extra Firm side is a 9 — that's very close to the firmest a mattress can be.
And the Plank Firm is also exceptionally flat, especially if you switch to the Extra Firm side (compared to the bouncy quilting of the DreamCloud at #1.) There's almost no sink, with minimal quilting providing some pressure relief. We found back sleeping comfortable on both sides, while our front sleepers preferred the Firm feel; the Extra Firm was just a touch too hard on the stomach.
There's no doubt that this is going to be a divisive mattress
Side sleepers will also prefer the Firm feel, although dedicated side sleepers should consider a plusher mattress altogether. Even the Siena at #3 would be better, as it has some squidgy cushioning. But one advantage of the firmness is edge support: the Plank is as strong at the sides as it is at the center. Combined with excellent motion isolation, this is a good choice for co-sleepers who want to use the entire surface of the mattress.
However, the Plank Firm can sleep a little warm and hot sleepers should consider paying to upgrade to the GlacioTex cooling cover. There's no doubt that this is going to be a divisive mattress. Our testers were impressed, but if you're after sink-in coziness, it won't deliver.
What we like about it...
✅ The firmest mattress we've tested: The Plank Firm is the "firmest, flattest" mattress on the market, with two sides offering almost no-sink.
✅ Head-to-toe support: The Plank Firm lifts the body and holds everything — from the head to the tips of your toes — in alignment. You don't have to worry about your lower back sinking and causing discomfort.
✅ Edge support is a exceptional: You can sprawl across the surface of the Plank Firm mattress and never feel like you're going to slide off. It's some of the best edge support we've found in a mattress.
What we don't like about it
❌ Uncomfortable for side sleepers: While the Firm side of the Plank offers a tiny bit of cushioning, this is not a mattress for side sleepers. The Siena (#3) is better for side sleepers who want a firm feel.
❌ You sleep warm: The Plank doesn't have awful heat retention, but it can warm up overnight. For warm sleepers seeking a firmer foam mattress, the Cocoon by Sealy Chill (#8) is superior.
❌ You want a luxury finish: The Plank Firm keeps a simple and streamlined look and the lack of quilting contributes to the firm feel. But if you want a mattress with a more inviting design, consider the DreamCloud (#1).
Features | In brief | Score |
|---|---|---|
Support and comfort | This is very much linked to your sleep style: for back and stomach sleepers, we give it a 4. Side sleepers, 3 out of 5. | ★★★★ |
Pressure relief | It takes a moment to appreciate the pressure relief, but there's enough for back and front sleepers (but not for side sleepers). | ★★★★ |
Temperature | There's some slight heat retention. We recommend hot sleepers upgrade to the GlacioTex cooling cover. | ★★★½ |
Motion isolation | The Extra Firm side has slightly superior motion isolation, but all-round the Plank Firm absorbs movement well. | ★★★★½ |
Edge support | Hard to fault, the Plank Firm is sturdy up to the corners and sides. | ★★★★★ |
Build quality | A solidly-made bed, and the dual-sided flippable design could potentially improve longevity. | ★★★★ |
When, where and how to buy
Plank Firm is owned by Brooklyn Bedding and the 25% off sale is evergreen. The queen has an MSRP of $1,332, but you'll frequently see it on sale for $999. We often see the saving increase to 30% around the major holidays, such as Presidents' Day, Memorial Day and Black Friday. This deal pops up semi-regularly, so if you don't need your new mattress right away, there's an advantage to waiting.
You can choose to upgrade the Plank Firm Mattress with a cooling cover crafted with GlacioTex materials, which will add roughly $100 to the overall price. All sizes of the Plank Firm come with a 120-night trial and a 10-year warranty.
When I first tried the Plank Firm, I though the mattress was way too hard for me to ever drift off comfortably. But once I was used to the incredible firmness, I could appreciate the subtle cushioning and not-so-subtle support. Stomach sleepers and back sleepers will appreciate how the mattress lifts the lower back, while the edge support is outstanding. However, there's almost no cushioning, which spells aches and pains for side sleepers.

6. The best mattress in a box for pressure relief
Quick summary
Purple is a pioneer in the online mattress space, and the Purple Plus is our favorite mattress for sleepers seeking relief from sore joints. Thanks to a combo of the brand's famous GelFlex Grid and multiple foam layers, the Purple Plus is somehow soft and firm in all of the right places.
The Purple's adaptable grid ensures cushioned joint relief and proper support for your spine, no matter how you lay. And thanks to the GelFlex Grid, you're likely to sleep cooler than you would on a comparable all-foam bed. But you may need to adjust to its squishy feel — for a classic foam feel, try the Nectar at #2.
Read what we liked, didn't like, and how to buy it ▼
The GelFlex Grid means the Purple Plus mattress won't appeal to everyone, but if you can put up with a slightly unusual feel, you'll enjoy unique pressure relief.
Our review: in more detail
The premium Purple Plus is a step up from the upper mid-range Purple Original mattress. It boasts an extra three inches of support foam plus a breathable comfort layer that works with the GelFlex Grid to promote airflow.
The targeted support and relief of the Purple Plus stood out to our testers. While the Purple Original has a uniform medium-firm feel (7 out of 10), the Purple Plus felt markedly firmer in the center yet softer at the top and bottom. Our testers rated it a 6 out of 10 along the top and bottom but a 7.5 in the center.
The Purple Plus feels a little like you float on top of the mattress while sinking in slightly.
As a result, our testers felt at ease no matter their sleep position. The extra few inches of support foam prevented us from sinking too low, and the GelFlex Grid softly cradled our shoulders, hips, and knees. The Purple Plus feels a little like you float on top of the mattress while sinking in slightly.Unlike most memory foam mattresses, the Purple Plus doesn't trap heat so you can remain cool, cozy and pain-free.
Co-sleepers will appreciate the high level of motion isolation, as the Purple Plus does an excellent job of dampening movement. On the other hand, edge support isn't on the level of the PlankFirm (#5). It's also not cheap, but it's still a more affordable option than a Tempur-Pedic – especially if you want a pressure-relieving mattress that won't leave you sweaty.
What we like about it...
✅ Targeted support and relief: We don't know how Purple does it, but its GelFlex Grid is soft under the shoulders, hips, and knees yet firmer along your lumbar. This will ease your joint pain while keeping you well-aligned, no matter your sleep position.
✅ Breathable and cool: Another benefit of the Purple GelFlex Grid is the thousands of air holes that prevent heat from getting trapped. As a result, our testers didn't wake up hot and bothered.
✅ Dampens movement: The foam layers in this mattress do a sound job of dampening movement. You'll barely feel your partner when they change positions or get in and out of bed.
What we don't like about it
❌ An unusual feel: The squishy, adaptive sensation of the GelFlex Grid will elicit strong opinions. You'll either love it or despise it. If you fall into the latter camp, try the Nectar (#2) for a similar level of pressure relief.
❌ Weaker at the edges: The Purple Plus scored just above average for edge support in our tests, but if you often sit on your bed or sleep close to the edge, you'll want a mattress that performs much better in this area.
❌ Poor extras for a high price: Relative to a Tempur-Pedic, the Purple Plus is a bargain, but it's a premium mattress in the broader market. The extras aren't anything special, either.
Features | In brief | Score |
|---|---|---|
Support and comfort | Soft and squishy yet supportive; our testers were comfortable in any position. | ★★★★½ |
Pressure relief | The Purple Plus withstands weight well and provides ample contouring along all the pressure points. | ★★★★½ |
Temperature | On par with the best cooling mattresses – pair with Purple sheets for optimal results. | ★★★★★ |
Motion isolation | Despite the buoyant surface, the Purple Plus doesn't let much movement escape beyond the point of contact. | ★★★★½ |
Edge support | Passable, but our testers expected more for a premium mattress such as this. | ★★★½ |
Build quality | The Purple Plus made a good first impression with our testers, but some Purple customers report indentations and sagging over time. | ★★★★ |
When, where and how to buy
The Purple Plus sits at the top of the Purple Essential collection. It's a premium-priced mattress, with a queen retailing for $1,899. You can save during Purple mattress deals, especially during Black Friday. However, Purple sales are hard to predict, so if you see a deal, we recommend snatching it up.
The Purple Plus comes with a 10-year warranty and a 100-night trial. These are standard benefits, but disappointing, considering the price — and the unusual feel. A longer trial period would have been welcome, allowing people ample time to decide if the GelFlex Grid works for them.
There's nothing else quite like the Purple Plus in this guide, with a unique feel courtesy of the GelFlex Grid. This geometric comfort layer bends to the body to create a floating pressure relief that eases joint pain. You really can feel the grid, however, which isn't an aspect everyone enjoys.

7. The best cooling mattress in a box
Quick summary
The Bear Elite Hybrid combines outstanding temperature regulation with excellent pressure relief and lumbar support making it a great mattress for hot sleepers and back pain sufferers. It impressed us enough to place first in our overall ranking of the best cooling mattresses.
The brand's thoughtful use of Celliant fibers in the optional cover offer the exceptional cooling power along with recovery technology to promote overall wellbeing. There are three firmness options to suit every sleep style and bed-sharers will appreciate the low level of motion transfer. It's pricey, however, with the Cocoon by Sealy Chill below a cooling option for tighter budgets (even if it lacks the chilled feel of the Bear.)
Read what we liked, didn't like, and how to buy it ▼
Without the Celliant cover, the Bear Elite Hybrid is a supportive mattress with enough choice to suit most sleepers. Upgrade to the cooling cover, however, and the Bear becomes a dreamy mattress for hot sleepers.
Our review: in more detail
The 5-layer, 14" tall Bear Elite Hybrid is available in three firmness levels (soft, medium, firm) and there's the option to upgrade with a Celliant-infused cover for additional cooling. We tested the medium Bear Elite Hybrid with the Celliant cover upgrade and rated in highly in key areas including support, comfort, motion isolation, edge support and pressure relief alongside temperature control.
We found the medium Elite Hybrid sits at 6 out of 10 on the firmness scale, in line with the brand's rating. There's minimal sinkage which our lead tester found most comfortable for back and stomach sleeping. This model will also suit side sleepers who don't need extra cushioning, although we'd recommend going softer if you like your mattress to have more give (luckily, the Bear Elite comes in a softer feel, but the Helix Midnight Luxe at #4 is another good option.)
For chronically hot sleepers, there's no better mattress-in-a-box we've tested
The Celliant-infused cover is the standout feature of this cooling mattress, a synthetic fiber that converts body heat into infrared energy, which is reflected back into the body to improve thermoregulation. The fiber also wicks away moisture to create a cooler sleep environment. That said, the Bear Elite Hybrid still sleeps cool even without this upgrade thanks to its layers of copper-infused memory foam and breathable coils.
For chronically hot sleepers, there's no better mattress-in-a-box we've tested than the Bear Elite Hybrid. However, if you only need a mild boost in cooling, the Cocoon Chill below may be a better option, especially if you're on a tighter budget.
What we like about it...
✅ Exceptional cooling with the cover: If night sweats and hot flashes regularly prevent you from achieving quality sleep, the cooling prowess of the Bear Elite Hybrid with Celliant-infused cover will do a lot to quell those disturbances.
✅ ...And good cooling without it: While we recommend adding the cover if you're a very hot sleeper, the Bear Elite sleeps neutral without the additional feature.
✅ Different firmness options: The Bear Elite Hybrid is available in three different firmness levels (soft, medium, firm) so you can customize your mattress based on your sleep style and body type.
What we don't like about it
❌ A premium cooling choice: The Bear Elite Hybrid is a premium cooling mattress with a price tag to match. If overheating is an occasional disturbance and not a nightly thing, try the more affordable Cocoon Chill (#8).
❌ Not much cushioning: A lack of soft cushioning is one of the reasons the Bear Elite Hybrid maintains a breathable feel (foams can trap heat), but it does mean this isn't a plush bed. The Leesa Sapira (#9) is cozier, but on the flipside, sleeps warmer.
❌ Weak at the far end of the bed: The only drawback we found in our Bear Elite Hybrid testing was the lack of edge support at the foot of the bed. The DreamCloud (#1) is better or try the Saatva Classic for a hybrid with exceptional edge support.
Features | In brief | Score |
|---|---|---|
Support and comfort | Three firmness levels available and strong lumbar support. | ★★★★ |
Pressure relief | Side sleepers would benefit from the softer model. | ★★★★ |
Temperature | The best cooling mattress we've tried thus far. | ★★★★★ |
Motion isolation | Scored highly in our motion isolation tests and our reviewer didn't feel their partner's movements next to them. | ★★★★½ |
Edge support | Edge support is strong along the sides but lacking at the foot of the bed. | ★★★★ |
Build quality | The mattress has a high-density foam layer to maintain structural integrity and two handles on the side for easy maneuvering. | ★★★★★ |
When, where and how to buy
Among cooling mattresses, the Bear Elite Hybrid is one of the better value options out there, sitting at the upper-mid range to premium pricing bracket after an evergreen discount. It also comes with two free pillows, a 120-night trial, and an unbeatable lifetime warranty.
A queen size has an MSRP of $2,305 without the cooling cover, but the sale knocks it down to $1,614. Add the cover and the price rises to $2,505 MSRP for a queen and $1,754 in the 30% off sale. Bear does sometimes increase the discount to 35% off even 40% off on special occasions. However, this typically only happens during the major sales days, and compared to some other brands these sales are rare.
The Celliant-infused cover transforms the Bear Elite Hybrid from a good cooling mattress to one of the best cooling mattresses around. The clever fiber absorbs heat and reflects it back as infrared energy, for a cooler (and more scientific) sleep feel. Don't think it's all about the cooling, however. Beneath that cover is a supportive mattress with great motion isolation and three firmnesses to suit different sleep needs.

8. The best budget cooling mattress in a box
Quick summary
The Cocoon Chill Memory Foam is another bed-in-a-box that features in our best cooling mattress guide. Made by industry giant Sealy, it has a special, stretch-knit cover that's infused with advanced phase-change material to keep sleepers comfortable — but minus the heavy price tag of its cooling rivals.
As a cheaper all-foam mattress, we weren't expecting much from the Cocoon by Sealy Chill, but it exceeded our low bar and then some. It can't compete with the exceptional cooling of the Bear Elite Hybrid Mattress above, but on the other hand, it's about $1,000 cheaper. Beyond cooling, the medium-firm feel is suitable for most sleep positions, and while there's not much body contouring, the pressure relief is exceptional.
Read what we liked, didn't like, and how to buy it ▼
It's rare for an all-foam mattress in this price bracket actually sleep cool, but the Cocoon by Sealy Chill mattress is an affordable choice for hot sleepers on a budget.
Our review: in more detail
Our testers were amazed by the cooling prowess of the Cocoon Chill, given that this is a boxed foam mattress that sits at the lower end of the price spectrum. While it doesn't have quite the chilling powers of the pricier Bear Elite Hybrid (#7), we still think it did a serviceable job of maintaining a comfortable sleep temperature.
Designed to adapt to your body to provide tailored support all over, this medium-firm mattress has three different foam layers. At 10" deep the Cocoon Chill is a decent height, but bear in mind that its memory foam layer is one inch thinner than the Nectar (#2) so it won't 'hug' your body.
There's no denying you get a lot for your money here
If you're looking for a good side sleeper mattress, chances are you'll love sleeping on it. Likewise, if you're a back or front sleeper, you'll probably find this boxed mattress comfortable, too, but you may be better suited to a firmer option, such as the Cocoon Chill Hybrid or the DreamCloud further up this list.
Overall, we were impressed with the comfort and cooling abilities of the Cocoon Chill and gave it superior marks for motion isolation, as well. There's no denying you get a lot for your money here. It even comes with free sheets and pillows, a practice that rivals Nectar and DreamCloud have since done away with.
What we like about it...
✅ Good cooling on a budget: The Cocoon Chill's cooling cover does a fine job of drawing away body heat. For an all-foam mattress, our testers were surprised at how comfortably they slept.
✅ Some of that memory foam 'hug': You won't find a deep sink here, but the Cocoon Chill does exhibit some of that traditional memory foam 'hug' that'll benefit your pressure points, especially when side sleeping.
✅ Free bedding and pillows: Whether you're buying a new mattress size or simply need to refresh your sheets and pillows, buying the Cocoon Chill will help you save time and money as you'll get those items included for free with purchase.
What we don't like about it
❌ Won't suit very hot sleepers: With the Cocoon Chill, you get what you pay for – and that's not a bad thing. However, there are better (albeit more expensive) options if you deal with severe overheating. For that, I recommend the Bear Elite above or the GhostBed Luxe mattress in our Also Tested section.
❌ Not much body contouring: The comfort foam layers are relatively thin, meaning you won't sink into this mattress. That helps keep things cool, but if you want a cushioned feel, try the Nectar at 2#.
❌ Hit-and-miss edge support: Considering the Cocoon Chill avoids one common pitfall of cheaper all-foam beds, overheating, we had high hopes for the edge support. However, the mattress is weaker at the sides — consider upgrading to the hybrid model or the DreamCloud at #1.
Features | In brief | Score |
|---|---|---|
Support and comfort | Expect to sleep 'on top' of the surface rather than 'in' it – but if you weigh over 230lbs, you'll likely find it too soft. | ★★★★ |
Pressure relief | Our tester noticed some of that classic memory foam feel, but the contouring here is much more subtle. | ★★★★ |
Temperature | As a budget-friendly all-foam mattress, the Cocoon Chill exceeded our expectations. We credit the cover and lack of a deep sink. | ★★★★½ |
Motion isolation | Minimal bounce, and our testers could barely tell there was another body next to them. | ★★★★½ |
Edge support | Decent, but for steadier sides, upgrade to the Cocoon Chill Hybrid. | ★★★ |
Durability | Well-made for its price point, but it'll likely last as long as a standard all-foam mattress. | ★★★★ |
When, where and how to buy
We've been tracking the Cocoon by Sealy Chill mattress sale for a while now and the price hasn't budged. So go ahead and ignore that countdown banner at the top of the brand website — we'll be very surprised when this sale finally comes to an end.
The permanent 35% off sale reduces a queen size Cocoon Chill mattress from $1,079 to $699, and you get a free bedding bundle included. This is a nice perk, particularly if you're looking to refresh your entire mattress setup. You'll also recieve a 100-night trial and a 10-year warranty.
Past-season Cocoon by Sealy Chill memory foam mattresses do pop up from time to time on third-party retailers (such as Walmart.) These beds tend to come with massive discounts, but you do sacrifice the sleep trial and free bedding.
I used to think budget-friendly all-foam cooling mattress was an oxymoron, but the Cocoon by Sealy Chill proves you can enjoy cooler sleep for less. There might not be much body contouring, but our testers were still impressed by the pressure relief. For increased support and an even cooler feel, however, I recommend upgrading to the hybrid model.

9. Best mattress in a box for couples
Quick summary
The Leesa Sapira Hybrid is the brand's best-selling mattress and it impressed our testing team with its five-star motion isolation. Hybrid mattresses tend to be bouncier than their all-foam counterparts, but the Leesa Sapira dampens movement exceptionally well. We recommend it to light sleepers who share a bed with a fidgety partner and want to avoid frequent wake ups.
We're also fans of the high-quality foam layers, which no doubt play a role in the Sapira's excellent motion isolation (and high price.) We found it nestles the body without providing too much sink, with a fast response that keeps you cradled even if you move around. It doesn't offer the value for money of something like the DreamCloud or Nectar that top this guide, but it is GREENGUARD Gold certified.
Read what we liked, didn't like, and how to buy it ▼
For side and back sleepers who like to move around but hate feeling their partner fidget, the Leesa Sapira Hybrid mattress offers the perfect balance of motion isolation and easy movement.
Our review: in more detail
Our testers slept on a queen Leesa Sapira mattress for three weeks. According to Leesa, this bed has a medium to medium-firm feel (6-8 out of 10 on the firmness scale). We think it skews closer to medium, rating it a 6.5. Like the Nectar at #2, our testers liked it most for side and back sleeping.
Despite having some bounce to it, the Sapira doesn't transfer motion to the other side of the bed when you move around. This was evident in our drop tests and real-world experiences. Our tester described it as "an unequivocal thumbs up for co-sleepers, fidgety or not." And despite the exceptional motion isolation, it's easy to move around on the Sapira. That's a win for both the fidgety partner and the person they share with.
An unequivocal thumbs up for co-sleepers, fidgety or not
As for other areas of performance, the Leesa Sapira isn't as breathable as we expected. Despite a cool-touch cover and a layer of coils, our lead tester occasionally slept warm on this bed (for a cooling hybrid, try the Bear Elite Hybrid Mattress at #7) Edge support also isn't on par with other mattresses at this price point, so beware if you're one to sleep with a partner who slowly nudges you toward the edge – perhaps try the Plank Firm (#5) instead, if maximizing the surface area is important to you.
Those demerits aside, we strongly recommend the Leesa Sapira if you're a combi side/back sleeper who wants to spare yourself (or your sleeping companion) from sudden unpleasant wake ups. Plus, it's a well-made bed with high-quality dense foam layers that won't warp right away – that helps justify the cost in my opinion.
What we like about it...
✅ Absorbs pretty much all movement: If you're the type to be jolted awake if your partner ever-so-slightly moves a muscle, the Leesa Sapira will eat those movements right up so you can keep snoozing peacefully.
✅ Suits ombi side/back sleeper: This is a true medium mattress, so side sleepers and most back sleepers will appreciate the balance of relief and support here.
✅ Built with quality materials: Yes, it's expensive (even when it's on sale), but the Leesa Sapira uses high-density foams that won't degrade quickly with nightly use.
What we don't like about it
❌ Can sleep warm: We were underwhelmed with the Leesa Sapira's cooling capabilities — the cool-touch cover only did so much to keep our lead tester comfortable. The similarly-priced Bear Elite Hybrid (#7) is better value for hot sleepers.
❌ Weaker at the edges: You won't want to spread out on this mattress due to weak edge support. The Plank Firm (#5) and Midnight Luxe (#4) are two beds on this list that you'll want to check out if you want to maximize your space.
❌ High price but budget benefits: The Leesa Sapira's extras are painfully average for what you pay. The DreamCloud (#1) offers a year-long trial and a forever warranty for a fraction of the cost.
Features | In brief | Score |
|---|---|---|
Support and comfort | Its medium firmness will provide most ightweight to average weight side sleepers with the support and comfort they need. | ★★★★½ |
Pressure relief | Deeper relief than similar mattresses of this firmness we've tested, but balanced by the taut, responsive surface. | ★★★★½ |
Temperature | A let-down, as the cool-to-the-touch cover did little to save our testers from a SoCal summer. | ★★★½ |
Motion isolation | Yes, it's bouncy, but the Sapira Hybrid still aced our real-world and objective motion isolation tests. | ★★★★★ |
Edge support | The Sapira Hybrid could be steadier here, but we never felt in danger of falling overboard, either. | ★★★½ |
Build quality | We think the high-quality dense layers of foam justify the high cost. | ★★★★½ |
When, where and how to buy
Even after regular discounts, the Leesa Sapira is still a premium-priced mattress. The 20% off sale reduces a queen from $1,999 to $1,500, but we have seen 25% off around peak sales days. There's also a 100-night trial and 10-year warranty – and a free pair of pillows is often included, too.
Leesa mattresses are sold at a range of third-party retailers including Amazon, Home Depot and Target, but they usually follow Leesa's standard sale pricing. Plus, buying directly from the manufacturer is better for hassle-free aftercare. However, we have sometimes spotted better discounts from third-party retailers on rare occasions, such as Amazon Prime Day.
If you share a bed with a fidgeter, you'll know their restless dreams often become your disturbed nights. Our testers found the Leesa Sapira simply eats up movement, meaning light sleepers can share with their partners / kids / pets and still get decent shut-eye. It's not the best value for money mattress in this guide, but the materials are high-quality and the sleep feel is plush.

How we test mattresses in a box
The Tom's Guide mattress review process is editorially independent and not influenced by any third parties. We conduct market research to see which new boxed mattresses are being released, then contact the brands for review samples. Every mattress in this guide has been selected by our editorial team.
Our expert mattress testers sleep on each mattress for at least three weeks, which is roughly how long it takes for your body to get used to a new mattress. However, firmness and comfort are subjective so we also ask a trusted and experienced testing panel.
Our mattress in a box testing panel is made up of people with different sleep needs and body types. This ensures we get a well-rounded view of how a mattress feels and performs for different body types and sleeping positions.
We don't just sleep on these mattresses – we also run a series of tests for an objective look at their motion isolation, pressure relief, and edge support. After analyzing our test data and conducting extensive user review research, we rate each mattress on a 5-point scale.
All of this in-house testing data, plus our user review research, is then used to create a final review score for the mattress in a box. If it's high enough, the bed will be added to this guide of the year's best beds-in-a-box.
These processes enable us to produce accurate, well-balanced, and data-backed mattress reviews to help you easily decide whether the mattress you’re interested in really is the best choice for you. See our mattress methodology for more.

Mattress in a box FAQs
What is a mattress in a box?
A mattress in a box is a memory foam or hybrid mattress that has been machine-compressed into a smaller size, tightly rolled, then packed into a sturdy cardboard box for shipping to your home. Shipping times vary by brand, but you can get a boxed mattress as fast as within two working days.
Once that box arrives at your door, your job is to unbox it. Each mattress in a box is covered in a reinforced plastic cover, and many brands give you a tool to slice through that covering more easily. Once the mattress has been fully unpacked, pop it on your bed base where it will begin to regain its full shape.
While they are the same as regular mattresses once fully decompressed, a mattress in a box takes anywhere from a few hours to a few days to be ready to sleep on. Emma mattresses, for example, are ready to sleep on in a few hours, while Nectar mattresses take up to 72 hours.
You may notice a bit of a smell at first, but this mattress off-gassing is normal. Just open the windows and it should soon pass, leaving you to enjoy your comfy new bed. To care for your new mattress in a box, cover it with one of the best mattress protectors to safeguard against stains.
Casper has been credited with making beds-in-a-box popular since its launch nearly 10 years ago, and now we also have the likes of Purple, Layla, Nectar, Helix and many others.
In terms of warranty, coverage ranges from 10 years to a forever warranty (Nectar and DreamCloud), but we’d advise you to check the small print so that you know what will and won’t be covered. For further guidance, read our feature on how do mattress warranties work.
Are mattresses in a box any good?
Yes, boxed mattresses can be excellent if you pick the right one. We've spoken to experts from the mattress industry to get a definitive answer on if beds that come in a box are good, and the short answer is that the quality of the mattress is much more to do with the specific model than whether it has been compressed or not. There are plenty of fantastic boxed options – such as those included in our ranking – but also plenty of rubbish cheap boxed mattresses that should be avoided.
Boxed mattresses are often delivered quicker and are easier to maneuver, but you'll avoid decompression time and perhaps also off-gassing if you go for a traditional option.
It’s easy to look at the cheaper price tags of some mattresses in a box and dismiss them as being too cheap to be supportive or comfortable, but that simply isn’t the case. My team has spent hundreds of hours sleeping on some of the top boxed mattresses and find them equally as comfortable as traditional mattresses sold in-store.
Do you need a box spring for a mattress in a box?
Many years ago, a box spring was a must for your mattress. These days, it's not a necessity and in a lot of cases, using a box spring with your boxed mattress can void its warranty.
Read more: What is a box spring?
The reason? Modern mattresses are built to be sturdy enough that you can forego a bed base and simply put them on the floor (though we don't totally recommend this). Box springs made sense when thinner innerspring mattresses were the standard, as they provided a boost in support, height, and airflow. Today's memory foam, latex, and hybrid mattresses in a box should be fine with a foundation instead.
Mattress in a box expert buying advice
How to choose the best mattress in a box
With more and more options available for buying a mattress in a box, it’s now easier than ever to find something that suits your sleeping position, body weight and any particular needs you might have when it comes to getting a restful night’s sleep.
Things to look out for when buying a bed-in-a-box online include:
Features – If you need extra features from a mattress to help you sleep, then there’ll be something for you, whether you sleep hot, need more pressure relief, or extra support for backache. Plenty of mattresses now come with innovative tech and eco-friendly materials too, so whatever your concerns, it should be covered.
Firmness – just like standard mattresses, beds in a box come in a variety of firmnesses. If you know you will likely need a firmer mattress for instance, check before you buy to ensure you are getting the most comfortable choice for you.
Trial period and free delivery/returns – many top brands offer mattress trials on their mattresses, giving you the chance to try the mattress out for yourself. It’s always a good idea to take advantage of trial periods, and if you decide the mattress isn’t for you, check that you can get a full refund.
This takes a lot of the stress out of buying a mattress online, especially if the mattress is expensive. Also check if the company offers free returns so there’ll be no surprises if you do need to send the mattress back.
Reviews – online reviews often give you extra information about the mattress, including feedback after a few weeks’ use and a closer assessment of the feel and comfort for different body weights. If you have decided on a boxed mattress, compare a few user reviews on the brand websites with those elsewhere too.
When is the best time to buy a mattress in a box?
There are definitely key periods throughout the year when it’s better to buy a boxed mattress, and chief among these is the Black Friday mattress deals, where prices are at their lowest and discounts are at their highest.
These often roll over into Cyber Monday mattress deals, which is the first Monday immediately following Black Friday, and you may even see some higher discounts on Cyber Monday when brand’s mount last-ditch efforts to attract your custom before Christmas.
Beyond that, the Memorial Day mattress sales in May are another key time to buy a mattress in a box for less than normal, with retailers looking to shift older stock before new ranges arrive in the summer. Labor Day mattress sales in September are also a good time to look, as they feature some of the lowest prices before Black Friday season.
What’s the difference between a mattress in a box and a traditional mattress?
When it comes to making the distinction between a mattress in a box and a traditional mattress, it's all about the packing process. A traditional mattress is delivered flat, but a mattress in a box is compressed with a heavy weight, rolled in plastic, boxed, and delivered to your door. When you open the packaging, the mattress unrolls and expands to its previous shape.
This packaging negates the need for an expensive brick-and-mortar store, and the saving is passed on to the consumer. You can get a great quality bed for less, with regular online mattress sales helping you save further.
