Mattresses in a box are known for their convenience — the mattress you want, on your bed frame, without leaving the house (or dealing with pushy sales people.) And in 2026 the boxed bed market is bigger than ever, so there's more choice for shoppers of every sleep need.

The bad news is that not all boxed beds are created equal. To be honest, some are more comfortable left in the packaging. That's where we come in. Our expert team has spent hundreds of hours testing over 130 beds to find the best mattresses you can buy online. The beds below have been vacuum sealed, rolled and then put through the paces in our Sleep Lab and they still impressed.

How we test mattresses in a box

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.

Our mattress methodology consists of seven robust tests conducted in our Sleep Lab to capture objective data on the areas of a mattress that most affect your sleep comfort: pressure relief, temperature regulation, motion isolation and edge support. We also sleep on a mattress for at least three weeks and receive feedback from an expert testing panel. Finally we assess value for money and user scores before feeding data into our bespoke scoring system to create an overall review score. See all our mattress reviews here.

The DreamCloud Classic Hybrid Mattress takes the top spot because it delivers exceptional comfort in a convenient and affordable package — just what we expect from a mattress in a box. One of the best hybrid mattresses we've tested, the mid-range price undersells the quality of this bed, particularly when you consider the "outstanding performance" our expert testing team noted.

DreamCloud Classic Hybrid review scores

Temperature regulation: 4/5
Pressure relief: 4/5
Motion isolation: 3.5/5
Edge support: 4/5

During our mattress review process the DreamCloud Classic earned high marks across the board. With 4/5 stars for pressure relief, the DreamCloud was most popular with the side sleepers in our testing panel, as the quilted top contours to the body to alleviate sore shoulders. The temperature regulation is also excellent (4/5) and the "airy design" prevents excess heat from getting trapped. co-sleepers, you might notice some disruption — our tests found large movements bounced across the bed — but good edge support (4/5) means you can lie far away from your partner as they toss and turn.

While we think the DreamCloud Classic delivers a touch of luxury, for true indulgence you might want to upgrade to the DreamCloud Ultra Hybrid (although it's over double the price.) And for those seeking a more eco-friendly build, consider the Awara Natural Hybrid, made with latex foams. You'll struggle to get a better value hybrid but the Allswell is an option for shoppers on a budget — if you don't mind sacrificing some support and a lot of cushioning.

The DreamCloud isn't perfect but it's as close as we think you'll get in this price range; excellent for side sleepers, supportive for back sleepers, and breathable all-over. No wonder we gave it full marks for value for money, as it goes above and beyond the mid-range price tag. And in the permanent DreamCloud mattress sale, it's always a good time to buy — a queen is around $699.

Best budget mattress in a box

Going above and beyond what we expect from a cheap mattress, the Siena delivers incredible support at under $300 for a queen

Specifications

Type of mattress: Memory foam
Height: 10"
Available sizes: Twin, twin XL, full, queen, king, Cal king, split king
Price range: Budget
Best for: Back sleepers, stomach sleepers, shoppers looking to save
Who should avoid: Lightweight side sleepers

Reasons to buy

+
Impressive full-body support
+
Comfy for back and stomach sleepers
+
Sturdy at the edges for full use of the sleep surface
+
Minimal heat build-up
+
Absorbs movement from a restless partner
+
Fantastic value for money

Reasons to avoid

-
Likely lacks durability
-
Too firm for most side sleepers

Siena’s Signature Mattress is a boxed bed highlight, a low cost mattress that still delivers when it comes to comfort and support. Our testing team was (pleasantly) surprised by its performance in our Sleep Lab, although for an all-foam bed, you don't get much body contouring. However, you do get an exceptional amount of support, particularly for a mattress under $300.

Siena Signature review scores

Temperature regulation: 3.3/5
Pressure relief: 3.76/5
Motion isolation: 4.6/5
Edge support: 4/5

We put every mattress through the same testing process, from the cut-price Siena to the luxury Saatva; so the Siena held its own against some stiff competition. Particularly when it comes to motion isolation — it simply eats up movement from even fidgety co-sleepers. Edge support is also impressive (4/5), with the sturdy build supporting you right up the perimeter. In fact, the support all-over is exceptional, although pressure relief suffers from a lack of contouring (side sleepers, watch out.) And while 3.3/5 for temperature control indicates some heat build-up, it's a good score for a cheap foam bed.

If you have the money to invest in durability and you still prioritize firmness, the Plank Firm should offer a longer lasting build. The Nectar Classic is another good alternative, for those who want support in the master bedroom. But if you want to keep to a low budget but enjoy a softer feel, try the Zinus Green Tea Mattress.

We know budgets can be tight nowadays and if you’re looking to upgrade your sleep without breaking the bank, you’ll struggle to do better than the Siena. This firm feel means it does best suit back and stomach sleepers but combination sleepers should appreciate the touch of pressure relief. And it's always on sale, so you can shop now with confidence (a 180-night trial doesn't hurt either.)

Best memory foam mattress in a box

Classic memory foam cushioning, rolled up and sent to your door

Specifications

Type of mattress: Memory foam
Height: 13"
Available sizes: Twin, twin XL, full, queen, king, Cal king, split king
Price range: Mid-range
Best for: Side sleepers, aching joints
Who should avoid: Stomach sleepers, back sleepers looking for firm support

Reasons to buy

+
Soothing body contouring
+
Ideal for side sleepers with aching shoulders
+
Eats up disruptive movement
+
Doesn't trap body heat
+
Luxury foam feel under $1,000 for a queen

Reasons to avoid

-
Too soft for most stomach sleepers and some back sleepers

Most people expect a memory foam mattress to have a full-body 'hug' and that's what the Nectar Premier delivers; which is why we've awarded it the title of best all-foam boxed bed. It's at the higher-end of the mid-range category but we think the indulgent foam feel earns it that price tag, as does what our lead tester describes as "shoulder-soothing comfort for side sleepers and a body-hugging softness without the typical heat build-up."

Nectar Premier Memory Foam review scores

Temperature regulation: 3.5/5
Pressure relief: 3.24/5
Motion isolation: 4/5
Edge support: 4/5

Whether a hybrid or all-foam, every bed we test goes through the same mattress methodology. However, we do expect memory foam beds to perform better when it comes to motion isolation, something the Nectar Premier delivers (4/5.) The foams are slow moving which allows them to absorb vibrations and deliver that classic foam 'hug' to ease aches and pains. There's perhaps too much hug and not enough support, particularly at the lower back, but despite that we were surprised at how sturdy the sides were when getting in and out of bed. The temperature regulation is also strong (3.5/5), although very hot sleepers might notice excess heat lingers for a bit.

We've tested the best memory foam mattresses you can buy online and if you want a foam hug on a budget, try the Zinus Green Tea Memory Foam. It doesn't have the durability of the Nectar Premier, but it's exceptional cushioning on a budget. Alternatively, the Nectar Classic has a firmer feel but it's a great all-rounder for back and stomach sleepers looking to spend less. Or if you want to splash out, the Tempur-Pedic Tempur-Adapt mattress has everything you expect from a foam bed (but it's around double the price)

The Nectar Premier is a side sleeper mattress through and through. We had mixed results from back sleepers, although a 365-night trial means you have time to test it out (stomach sleepers, go for the Siena or Plank.) For a feel similar to Tempur Material but under $1,000 for a queen in the permanent Nectar mattress sale, the Nectar Premier offers good value, particularly as the high-quality build means we expect it to last upwards of seven years.

Best cooling mattress in a box

This mattress kicks out excess heat all night long, making it a dream for chronic hot sleepers

Specifications

Type of mattress: Hybrid
Height: 14"
Available sizes: Twin, twin XL, full, queen, king, Cal king, split king
Price range: Premium
Best for: Hot sleepers, side sleepers
Who should avoid: Those with need strong edge support

Reasons to buy

+
Ideal for chronic hot sleepers
+
Active cooling offloads excess heat
+
Multiple firmness options
+
Cushioned top soothes aches and pains
+
Easy to move around on

Reasons to avoid

-
Lacks support at the edges
-
You pay extra for all the cooling features
-
Bouncy feel might disturb light sleepers

Night sweats and overheating disrupt your circadian rhythm, which in turn disrupts your sleep. — the best cooling mattresses aim to kick out excess warmth so you can rest undisturbed. From our testing, there's no better boxed bed for cooling than the Bear Elite. A hybrid mattress packed with cooling tech, our lab testing shows it simply offloads heat to keep you dreaming comfortably.

Bear Elite Hybrid review scores

Temperature regulation: 5/5
Pressure relief: 4.6/5
Motion isolation: 3.2/5
Edge support: 2.5/5

Temperature regulation is a key part of out mattress testing process and the Bear Elite earned full marks here. It absorbs heat and then quickly chucks it out, ensuring you aren't bothered by lingering warmth. Of course, that's not enough to earn a place in this guide and the Bear Elite also delivers exceptional pressure relief courtesy of deep cushioning (and it comes in three firmness levels, to appeal to all sleepers.) The motion isolation is okay but heavy movement will likely disrupt light sleepers. Unfortunately, edge support is a weak point — our testers found themselves slipping off the sides.

Dedicated cooling mattresses are pricey but if you're looking for a breathable design on a tighter budget, we were impressed with the DreamCloud Classic and the Brooklyn Bedding CopperFlex Pro Hybrid (both under $1,000 for a queen.) For luxurious cooling, the Brooklyn Bedding ThermoBalance LX Elite is an indulgent choice, as is the Saatva Classic (although this one is delivered flat, instead of boxed.)

The Bear Elite Hybrid is ideal for chronic hot sleepers; those who frequently find their snooze cut short by overheating. The pressure relief of the Medium model we tested is also exceptional for side sleepers, although the Helix Midnight Luxe is better overall for side sleepers who don't sleep warm. A queen is typically around $1,485 in the standard Bear 30% off sale but if you can wait for a major holiday, Bear's biggest discount nets you 40% off.

Best mattress in a box for side sleepers

A perfect balance of cushioning and support to keep side sleepers happy all night long

Specifications

Type of mattress: Hybrid
Height: 13.5"
Available sizes: Twin, twin XL, full, queen, king, Cal king, short queen, RV king
Price range: Premium
Best for: Side sleepers, back sleepers
Who should avoid: Stomach sleepers, combination sleepers who like to move around

Reasons to buy

+
Incredible cushioning so no achy shoulders
+
Breathable
+
Holds the spine straight and supported
+
Comfortable for back and side sleepers
+
A good choice for couples

Reasons to avoid

-
Plush top means you might feel 'stuck' in the foams
-
Slight bounce might disturb light sleepers

We've got a lot of side sleepers on our testing team and it's the Helix Midnight Luxe mattress that impressed them the most, earning the title of best mattress for side sleepers. The Midnight Luxe proves that boxed mattresses can be just as luxurious as their traditional counterparts (and just as pricey), as a deep indulgent pillow top makes this bed a side sleepers dream.

Helix Midnight Luxe review scores

Temperature regulation: 4/5
Pressure relief: 4.5/5
Motion isolation: 3.5/5
Edge support: 4/5

Pressure relief is a must for side sleepers and our tests show the Helix Midnight Luxe mattress nails it. It's soft at the shoulders and hips but with an underlying support that also holds your spine straight, making it a winner for most back sleepers, as well. However, some of our team did feel 'stuck' in the plush top. Outside of pressure relief, the Helix impressed across the board, with a breathable feel (4/5) and sturdy edge support (4/5.) Light sleepers might notice some disruptive movement but our lead tester frequently shared the Midnight Luxe with two kids plus a cat, and she still loved it.

As it's built using high-quality materials to suit a specific type of sleeper, we think the Helix Midnight Luxe is good value for money (4/5.) However, side sleepers looking for a more affordable option should consider the DreamCloud Classic. And if the motion transfer is a deal-breaker, the Nectar Premier delivers side sleeper comfort without the bounce.

It's not just side sleepers who'll get on with the Helix Midnight Luxe; most back sleepers on our testing team loved it too. Overall, it's a strong all-rounder but the luxury price tag puts it behind our number one choice, the DreamCloud. If you're looking to save, Helix mattress sales are regular and it's worth waiting for 25% off —it's particularly prevalent around holidays.

Best firm mattress in a box

You wont get a firmer bed in a box — the support is next level but side sleepers will hate it

Specifications

Type of mattress: All-foam
Height: 10"
Available sizes: Twin, twin XL, full, queen, king, Cal king, split king, split Cal king, short full, short queen, short king, Olympic queen, RV king
Price range: Mid-range
Best for: Stomach sleepers, back sleepers
Who should avoid: Side sleepers

Reasons to buy

+
Non-stop full-body support to hold your spine straight
+
Excellent for stomach sleepers
+
Unusual double-sided design
+
Great edge-to-edge support
+
Fantastic motion isolation
+
950lbs weight capacity

Reasons to avoid

-
No handles for flipping
-
Can sleep warm
-
'Dead' feel won't appeal to everyone
-
Too firm for side sleepers

Mattresses in a box encompass every type of bed, including the uber-firm (and undoubtedly divisive) Plank Firm mattress. This is an all-foam bed like no other (at least, there's not many like it), a flippable design that's firm on one side and extra firm on the other. Our testers agreed this sturdy build results in incredible full-body support and at $999 for a queen in the sale, it's a competitive price for a niche design.

Plank Firm review scores

Temperature regulation: 3.5/5
Pressure relief: 3.5/5
Motion isolation: 4.5/5
Edge support: 5/5

It's a tale of two halves when it comes to pressure relief on the Plank. For side sleepers, it's far too hard for comfort. For back and stomach sleepers, the flat and unyielding design keeps the lumbar lifted and aligned to prevent back ache. This super-firm feel also results in next-level edge support; you could park a car on the sides. The foams have a 'deadened' feel which won't appeal to everyone but they do create exceptional motion isolation. However, the temperature regulation is a let down; our tester found themselves kicking off the covers many nights on the Plank Firm.

There aren't many beds like the Plank Firm around but the Siena mattress is a budget-friendly alternative for back and stomach sleepers. The Nectar Classic also offers firm support for less, although both options come without the Plank Firm's flippable USP. And we've touched on the deadened feel of the Plank (essentially, when you move the mattress stays completely still) so if you're after a bed with some bounce, consider the hybrid Helix Dawn mattress.

The Plank isn't a crowd-pleaser — side sleepers should stay away — but it's one of the best mattresses for stomach sleepers we've tested and the non-stop support helps reduce strain on the spine. It's also a design you won't come across elsewhere and if you're looking for support, we think it's worth the $999 price tag for a queen in the sale. You'll usually snag 25% off at Plank but look out for 30% off around the holidays.

Best mattress in a box for back and hip pain

Avoid waking up with aches and pains thanks to the targeted support for all types of sleepers

Specifications

Type of mattress: Hybrid
Height: 13.5"
Available sizes: Twin, twin XL, full, queen, king, Cal king
Price range: Premium
Best for: Sleepers with back pain
Who should avoid: Chronic hot sleepers

Reasons to buy

+
Zoned support to reduce back pain
+
Strong edges make it easy to get in and out of bed
+
Comes in three firmness levels
+
Plus option for those over 250lbs

Reasons to avoid

-
Not suitable for chronic hot sleepers

If you wake up with more aches and pains than before you went to sleep, you probably aren't getting the support you need from your mattress. But a boxed bed can help. The best mattresses for back pain aren't the realm of traditional or specialized beds, as the WinkBed mattress — a luxury hybrid mattress with integrated lumbar support — proved to our testers.

WinkBed review scores

Temperature regulation: 4/5
Pressure relief: 4/5
Motion isolation: 4.5/5
Edge support: 4.5/5

During our testing process one feature of the WinkBed stood out: edge support. The sturdy sides allow you to push against the mattress when getting in and out of bed, so there's no extra strain on your back. Overall, pressure relief impressed and with three firmness levels to choose from as well as a Plus model for sleepers over 250lbs, there's a WinkBed for nearly everyone — our tester recommends the Luxury Firm for back and side sleepers. The motion isolation also impressed, meaning sudden movements shouldn't cause a jolt but while our tester agreed the mattress was breathable, she didn't think the Frost Cooling cover upgrade was worth the money.

While the Luxury Firm feel is the most popular from WinkBed, dedicated side sleepers might want to opt for the Softer feel — or go for the Helix Midnight Luxe, which is quite literally made for you and offers excellent back support. The Bear Elite Hybrid is another good alternative, for those who need a cooler sleep space. Mattresses for back pain do tend to come with a high price tag but if you're after an affordable alternative, the DreamCloud is your best bet.

The dedicated support features of the WinkBed makes it a winner for soothing aches and pains, and the Plus option means it suits a type of sleeper even some of our top rated beds don't cater too. At $1,799 for a queen in the year-round sale we do think there are some luxury mattresses that deliver more for the money (the Saatva Classic, for one) but we do expect durable support if you're willing to invest.

Best organic mattress in a box

All the responsive pressure relief of a latex mattress on a mid-range budget

Specifications

Type of mattress: Latex hybrid
Height: 10"
Available sizes: Twin, twin XL, full, queen, king, Cal king, split king
Price range: Mid-range
Best for: Side sleepers, hot sleepers, eco-shoppers
Who should avoid: Light sleepers who are easily woken by movement

Reasons to buy

+
Responsive feel cradles the shoulders and hips
+
Strong edge support for full use of the sleep surface
+
Affordable eco-friendly build
+
Made with organic latex and cotton

Reasons to avoid

Light sleepers might find it bouncy

We told you boxed beds cover every type of mattress and that includes eco-friendly favorites like the Awara Natural Hybrid. Swapping traditional memory foam for organic latex and wool, at just $799 for a queen the Awara is one of the most affordable latex beds on the market. But our testers found it can hold its own against even pricier competitors, thanks to a responsive cushioned feel that side sleepers should love.

Awara Classic Hybrid review scores

Temperature regulation: 4/5
Pressure relief: 5/5
Motion isolation: 3/5
Edge support: 4/5

Over years of mattress testing, we've often noted that latex beds have a firmer feel than memory foam mattresses. The Awara bucks this trend. Yes, it's still a mattress you lie on top of but the responsive design means it moves around the body to cradle the shoulders and hips, making it suitable for side sleepers. The supportive overall is excellent, including at the perimeter, so our bed sharing lead tester could sleep right up the side. And you're unlikely to overheat, as we've found latex is a naturally breathable foam. But while the motion isolation is good. light sleepers are likely to notice some disruption from a partner moving.

The Awara's organic build does contribute to a slightly higher price tag so if you don't mind ditching the latex, the DreamCloud Classic delivers a better all-round performance for less. But if eco-materials are your top priority, the Avocado Green is a stand-out organic mattress. Or for something plusher, the Naturepedic Concerto Pillowtop is one of the best organic beds we've tested for side sleepers.

Eco-friendly shoppers often struggle to find a quality organic latex mattress on a budget but at just $799 for a queen year-round, the Awara shows greener shopping doesn't have to break the bank. And it doesn't skimp on performance, with a responsive and cushioned feel that will suit side and back sleepers. Light sleepers might find the bouncier feel disruptive (a softer foam hybrid will be a better alternative) but for most couples its as good for your sleep as it is the planet.

Plush foams make it hard to change position

Standing 15 inches tall and with a dense, plush pillow top, the DreamCloud Ultra Hybrid is so luxurious even the fussiest princess wouldn't notice if you hid a whole bag of peas underneath. This is true indulgence in a mattress and the "marshmallow-y" soft feel makes it perfect for side sleepers. At $1,999 for a queen it's most certainly an investment but it might be worth it if you want to recreate the feel of a 5-star luxury hotel mattress at home.

DreamCloud Ultra Hybrid review scores

Temperature regulation: 3.5/5
Pressure relief: 3.5/5
Motion isolation: 3/5
Edge support: 3.5/5

Some mattresses perform in all areas of testing to earn a place among our favorites while others deliver in one stand-out metric. The DreamCloud Ultra Hybrid is the latter. Our lead tester described the pressure relief as "sensational", with a true body-hugging feel that will impress side sleepers. However, you are swallowed by the mattress; that makes it hard to change position and if you do move, anyone else in the bed is likely to feel some disruption. But despite this close foam 'hug', it earned 3.5/5 for temperature regulation, meaning most can avoid sweaty nights. The edge support is decent (3.5/5) but with such a tall build those with limited mobility might struggle to get on and off.

For side sleepers looking to indulge without feeling like they're lying on a melting marshmallow, we recommend the Helix Midnight Luxe mattress. Conversely, for even more squishy softness, try the DreamCloud Luxe Memory Foam or the Helix Sunset Luxe. And while we found the temperature regulation decent, hot sleepers should opt for the superior cooling of the Bear Elite Hybrid or the Brooklyn Bedding ThermoBalance LX Elite.

The DreamCloud Ultra Hybrid delivers a luxurious feel to side sleepers and back sleepers. But the impressive height and plush foams are both its best feature and biggest disadvantages — it's a hard bed to move around on and to get in and of. And at $1,999 for a queen, we think there are better value luxury beds out these. However, we spend roughly one-third of our lives in bed and if you want to enjoy that time in gooey comfort, this might be worth the indulgence.

The Bear Elite Hybrid sleeps cooler

The mattress in a box market is expansive which is why you can now find a bed to suit every sleep style; for those with hip and joint pain who find warm nights are making their aches worse, the ThermoBalance LX Elite from Brooklyn Bedding is the mattress for you. It's luxurious (and expensive — a queen is $2,239.30 in the best of the Brooklyn Bedding sales) but packed full of specialist features and latex foams to enhance the sleep experience.

DreamCloud Classic Hybrid review scores

Temperature regulation: 4/5
Pressure relief: 4/5
Motion isolation: 3.5/5
Edge support: 4/5

The ThermoBalance LX Elite features 'triple cooling technology' and our tester found the mattress remained comfortably neutral even during an unseasonably warm spring (4/5); that means you're unlikely to exacerbate pains by kicking the covers off in a sweat. The sturdy edges (5/5) will also benefit aching joints, as you can push against the mattress without losing support. On that note, our lead tester is a marathon runner who needs a bed to ease strain at the hips, something the ThermoBalance LX Elite excels at (and it comes in three firmness levels, to suit every sleep need.) However, while the sink-in foams absorb most disruptive movement, they also make changing position a touch difficult.

We were impressed at how efficiently the ThermoBalance LX Elite wicks away night sweats but our lead tester has also slept on the Bear Elite Hybrid and found it cooler. However, if cooling doesn't matter to you and it's sore-spot soothing pressure relief you want, consider the Tempur-Pedic Tempur-Adapt mattress. And for those on a tighter budget, Brooklyn Bedding's CopperFlex collection delivers luxury-looking comfort for less.

Night sweats and hip pain are a one-two punch of snooze disruptors and a particularly common sleep complaint of perimenopausal and menopausal women. With pressure relieving foams, three firmness levels, good cooling and strong edge support, the ThermoBalance LX Elite offers an all-round solution. However, it's a pricey investment — 30% off sales that appear around the holidays are your best chance to save.

Recent updates

While the DreamCloud retains its position as our favorite mattress in a box, it's luxurious upgrade the DreamCloud Ultra Hybrid is a new entry at number 9, as it the Brooklyn Bedding ThermoBalance LX Elite at 10. After recent retesting, the Awara has replaced the Avocado Green as our favorite organic mattress in a box.

Brooklyn Bedding CopperFlex (twin): was $599 now $419.30 at Brooklyn Bedding

The CopperFlex Mattress from Brooklyn Bedding can't quite reach the luxury heights of the ThermoBalance LX Elite from the same brand but it still delivers cooler comfort while soothing aching joints. For a more indulgent feel on a budget, consider the CopperFlex Pro Hybrid Mattress.

DreamCloud  Luxe Memory Foam (twin)
DreamCloud Luxe Memory Foam (twin): $1,199 at DreamCloud

Expect plush, cloud-like comfort from DreamCloud's Luxe Memory Foam mattress, making it dreamy for side sleepers — although hot sleepers should stick with the Bear Elite Hybrid. At $1,599 for a queen it's perhaps not the best value mattress around but it does deliver marshmallow cushioning.

Our DreamCloud Luxe Memory Foam mattress review:
User score: ★★★★½ (1,200+ reviews)

Helix Sunset Luxe (twin)
Helix Sunset Luxe (twin): was $1,492 now $1,089 at Helix Sleep

As a softer alternative to the Midnight Luxe above, the Sunset Luxe doesn't have quite the same crowd appeal (it's less comfortable for back sleepers, for a start.) However for side sleepers who want even more body contouring, it's the superior choice. The best time to shop is the 25% off sale, but use code TOMS27 for a better discount and nab a queen for $1824 (was $2,498.)

Our Helix Sunset Luxe mattress review: ★★★★
User score: ★★★★½ (1,300+ reviews)

Cocoon by Sealy Chill (twin)
Cocoon by Sealy Chill (twin): was $539 now $349 at Cocoon By Sealy

An all-foam mattress at the low-end of the budget price bracket? The Cocoon by Sealy Chill shouldn't deliver the temperature regulation it does but this affordable memory foam bed goes against expectations to keep you cool. Deals vary but use code COCOON35 to snag the best price and a queen for $597 (was $919.)

Our Cocoon by Sealy Chill Mattress review:
User score: ★★★★½ (8,700+ reviews)

Nectar Classic Memory Foam (twin)
Nectar Classic Memory Foam (twin): $349 at Nectar Sleep

Firmer and more affordable than the Nectar Premier, Nectar's entry-level all-foam Classic mattress is a durable alternative to the Siena Signature. At $649 for a queen in Nectar's permanent sale it's excellent value for money but it doesn't deliver the sink-in foam experience of its pricier upgrade.

Our Nectar Classic Memory Foam Mattress review:
User score: ★★★★½

Zinus Green Tea Memory Foam (twin)
Zinus Green Tea Memory Foam (twin): was $212 now $170.99 at Amazon

For side sleepers, the Zinus offers oodles of pressure relief on a budget, although it does suffer from weak edges and a tendency to trap heat. But you might be able to overlook those faults if you can score a good deal: a queen is often around $230 on Amazon but on rare occasions, you can find it for under $200.

How we test mattresses in a box

The Tom's Guide mattress review process is editorially independent and not influenced by 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 mattress testing process is conducted in two parts: lab testing and an at-home sleep experience. This allows us to collect both objective and subjective feedback, to ensure our reviews are accurate and fair.

We test each mattress for key performance indicators. As well as comfort, support, and pressure relief, we test temperature regulation, motion isolatio,n and edge support.

For our temperature regulation tests, we deploy a thermal imaging camera to closely measure temperature changes. First, we ensure the temperature of the Sleep Lab is between 65 and 70°F, which is the best temperature for sleep. Using the thermal imaging camera, we then take a temperature reading at the four corners of the mattress, the center of the bed, and a designated hot spot (roughly where the middle of our tester will be).

Our tester then lies on the mattress for 15 minutes; every minute we take the same six measurements to monitor the MTI (Maximum Temperature Increase). The tester then leaves the mattress, and we again monitor for 15 minutes to determine how quickly the bed sheds heat.

To test for motion isolation, we use a drop test: a 5kg slam ball is dropped from 24 inches above the mattress onto one side of the bed, while an accelerometer on the other side measures the Initial Impact Absorption (IIA — initial force of the movement) and Motion Decay Speed (MDS — how long it takes the movement to stop.) We repeat the test 10 times and take an average.

We also conduct lab-based tests using members of our team to complete a series of low, medium, and high force movements (such as changing position) on the mattress, while another team member lies next to them and records what they feel.

Our edge support lab tests are two-fold, combining weight tests (placing 25kg at the side and foot of the bed to measure sinkage and response time) with the 'roll-off' test: how far can we get to the edge of the bed before we fall?

Comfort is subjective, but to objectively understand pressure relief and support we place a series of weights (10kg and 25kg) in designated 'sleeping areas' on the mattress. Using a laser pen we measure the initial sink of the weight, the sinkage after 5 minutes, and the recovery time. We also use our laser pen to measure spinal alignment — after 10 minutes lying on the mattress, is our testers spine still aligned?

Alongside lab testing, each mattress is taken home and slept on by a member of our sleep team for a period of at least three weeks. As well as providing valuable insight into comfort and support, our testers offer feedback on temperature regulation, motion isolation and edge support.

And to better understand the overall appeal of the mattress, we ask secondary testers with different body types and sleep needs to try the mattress and complete a feedback survey.

We also consider value for money: what are you getting for the price and does the cost match the mattress? Finally, we analyze customer reviews and brand claims, using this information to direct further testing.

We score all key criteria out of 5, based on a scoring rubric combining subjective and objective data. These scores are then added together to give a total score out of 5 for each mattress.

Beds in a box come in a variety of builds, feels and price points. This rigorous testing helps us better understand each mattress comparatively and objectively, to ensure we only recommend the best.

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.

How to unbox a mattress in a box

Unboxing a mattress is relatively easy although we recommend asking for a helping hand, particularly if you've ordered a full size or above.

The first thing to do is prepare your bed frame. In other words, remove your old mattress and bedding to make room for a new one. Next, take the rolled mattress out of its box. Open the box using scissors rather than a box cutter, to avoid damaging your mattress.

Then place the rolled mattress in its packaging onto your bed frame. Using scissors, carefully cut away the top layer of packaging, avoiding damaging the mattress within.

Unfold the mattress onto the bed frame, taking care to ensure it's the right way up and facing the right direction. Once you're happy with the placement, cut away the rest of the packaging carefully, using scissors.

However, mattresses can be quite enthusiastic to get out of the packaging: if your bed starts expanding before you've got it in place, don't panic. Simply adjust the placement once the mattress has finished the initial expansion.

Finally, remove the packaging and watch as the mattress expands. While this seems like a quick process (most mattresses immediately spring up), it can take up to 72 hours for the mattress to fully expand. Check the instructions to understand just how long you need to wait before sleeping on your new bed.

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.
