Best Amazon Prime Day mattress deals 2025 still live
Prime Day might be over but you can still save on a mattress on Amazon — our expert guide to the deals plus an overview of the July savings.

The Prime Day July 2025 sales event is over! After searching through thousands of Amazon listing to find the most compelling mattress discounts, a clear trend emerged: budget-friendly memory foam beds got even cheaper, with deals like the already affordable Siena mattress dropping to just $149 at Amazon (now back to $199.)
Discounts on past-season mattresses was another common thread and with these offers you could enjoy lower prices on older models of some of the best mattresses we’ve tested, like the Nectar Classic or DreamCloud Hybrid.
It was a well timed sale for anyone looking to spruce up their spare room or preparing to send their kids off to college. Anyone browsing for a luxury mattress, however, was better off shopping elsewhere, with rival sales at Helix and Saatva beating Amazon discounts on premium beds.
And I'm still tracking all the latest mattress discounts from across the web. Head to our mattress sales guide for all the best deals on top-rated beds to browse today.
But with the first four day Prime event over, it's time to reflect on the offers. While I spotted some deals shake up as the days went on, for the most part, the best sleep savings had dropped by day two. As it’s not unusual for sizes to sell out, my advice for next Prime Day is to shop early.
Speaking of next Prime Day, I’m expecting another sale in October. The October 2024 Prime Day event surprised me with savings on mid-range and premium mattresses — I'm hoping for something similar this year, to bridge the mattress deals gap between Labor Day in September and the Black Friday mattress deals bonanza in November.

Amazon Prime Day mattress deals 2025: The 3 best sales
1. Serta Five Star Mattress Tranquility 10" Plush Mattress: twin was $399 now $299.25 at Amazon
This Prime Day offer is still going as a 'Limited Prime deal' so expect the saving to finish soon. Pairing a thick Euro top with a spring base to emulate the design of many mattresses used in hotels, the Serta Tranquility is unlikely to match the 'five star' hotel comfort promised in its name, but we still expect ample pressure relief for side sleepers. And from legacy mattress brand Serta, we predict a high quality build, developed over decades of mattress making. A 10-inch Plush queen is still at its Prime Day price of $374.25 (was $499), so snatch this deal up before it ends.
User score: ★★★★½ (17 reviews)
2. Sealy Dreamlife 10" Foam Mattress: twin was $429 now $300.30 at Amazon
A twin Dreamlife 10" Foam is more expensive than it was during Prime Day... but only by $1. And if you're after a queen size, the 'Limited Prime deal' sale price of $409.14 is the same saving we saw during the big week itself. Made in the US, the Dreamlife mattress comes with a 10-year warranty and all the sleep knowledge Sealy has accrued in over a century making mattresses. Reviews suggest it's on the softer side of medium-firm so we recommend it for side sleepers.
User score: ★★★★½ (68 reviews)
3. EGOHOME 10" Memory Foam Mattress: twin was $137.99 now $129.99 at Amazon
If you need a mattress for a spare room or dorm room, the twin EGOHOME 10" Memory Foam is still at its Prime Day price of $129.99 and as the EGOHOME brand has impressed us with its value for money beds, we predict this is a smart budget choice. The queen size is more expensive than last week — now $189.96 compared to a Prime Day price of $151.32 — but it's still an inexpensive mattress.
User score: ★★★★½ (1,600+ reviews)
The best Amazon mattress sales we saw during Prime Day July 2025
1. Siena Memory Foam Mattress: twin was $199 now $149 at Amazon
The best cheap mattress we've tested, the all-foam Siena has a firm and supportive feel that's ideal for back and stomach sleepers (as well as perfect for your guest room.) In our Siena Memory Foam Mattress review we praised the breathable build — some cheap all-foam beds can sleep uncomfortably hot but the Siena stays neutral even throughout summer heatwaves. Prime members can get a queen for only $278 (was $349) which beats the Black Friday price and matches the mega saving we spotted during Memorial Day. With a 180-night trial and 10-year warranty, this deal is all-round excellent.
2. Zinus 12" Green Tea Memory Foam Mattress: full was $219.99 now $186 at Amazon
Delivering a squishy, body-hugging feel, our Zinus Green Tea Memory Foam Mattress review team agreed this bed is a dreamy choice for side sleepers (we tested the 10" and the 12" is likely even more cushioned.) Like many of the best memory foam mattresses it excels at pressure relief, cushioning the shoulders and hips to prevent aches and pains. We recommend pairing this mattress with your most breathable bedding — it can sleep hot — but at just $194 for a queen (was $229.99), it's a bargain. The best ZInus mattress deal this Prime Day is on the queen but it's an affordable mattress at any size.
3. DreamCloud Luxury Hybrid Mattress: twin was $419 now $319 at DreamCloud
One of the best hybrid mattresses we've tested, in our DreamCloud Mattress review we described it as delivering "affordable luxury" with a medium-firm feel that suits most sleep styles, a breathable build, and an indulgent finish. DreamCloud mattress sales rarely change so this is an unexpected price drop for Prime Day, reducing an older (but still highly rated) version of the DreamCloud to just $549 for a queen (was $665.) And you get a 365-night trial and a lifetime warranty.
4. Casper Sleep Element Mattress: twin was $395 now $276.50 at Amazon
Dropping to the lowest price we've seen this year, the Sleep Element is an affordable memory foam design from Casper, the brand behind some of the best mattresses in a box you can buy online. Like Casper's flagship all-foam mattress, The One, we expect the Sleep Element to deliver firmer support and top-notch motion isolation. Prime members can save 30% on a queen, reducing it to just $416.50 (was $595.) If that doesn't catch your eye, there are plenty more offers in this month's Casper mattress sale.
User score: ★★★★½ (5,800+ reviews)
5. Nectar Classic Memory Foam Mattress: twin was $349 now $296.64 at Amazon
This budget-friendly bed blew away our Nectar Classic Memory Foam Mattress review panel with its supportive build, breathable feel and incredible motion isolation. The medium-firm feel will suit most sleep styles but be aware it doesn't have the squishy, sink-in feel of other all-foam beds (you'll need to upgrade to the Nectar Premier for that.) Nectar mattress sales have a reputation for being predictable so this saving has taken us by surprise — a queen is now only $551.64 (was $649) and comes with a 365-night trial and lifetime warranty,
6. Tuft & Needle Kin 10" Hybrid Mattress: twin was $449 now $345.53 at Amazon
The Kin mattress is an Amazon-exclusive from popular boxed bed brand Tuft & Needle. Made in the US with Greenguard Gold certification, the hybrid uses T&N 'adaptive' foam to create bounce back pressure relief — when you move, the foam moves with you, so you never lose out on comfort. With 27% off a queen is now $585.47 (down from $799), a competitive price for a high quality hybrid.
7. EGOHOME 12" Black Memory Foam Mattress: twin XL was $309.99 now $260.80 at Amazon
We recently had a chance to test this affordable all-foam mattress and after a month of sleeping on it it was decided: this is one of the best mattresses on Amazon under $400 for a queen. The lead tester in our EGOHOME Black Memory Foam Mattress review team is a lightweight side sleeper who struggles to find a bed with enough pressure relief but the EGOHOME was just right, the slow moving foams contouring to the shoulder to prevent body aches. At $311.99 for a queen (was $429.99) is back down to one of the lowest prices we've seen year but act fast, as EGOHOME deals are typically short lived.
8. Ethical Mattress Co Latex Hybrid Mattress: twin was $698 now $558 at Amazon
If you want to make your sleep a little greener, this is the deal for you — 20% off the Ethical Mattress Co Latex Hybrid mattress reduces a queen from $998 to $798.40 at Amazon. The best organic mattresses typically use latex foams to create a bouncy and responsive feel with natural cooling. There aren't many latex mattresses on Amazon so this is an unexpected chance to save.
User score: ★★★★½ (74 reviews)
9. Signature Design by Ashley Chime 12" Mattress: twin was $368.99 now $204.05 at Amazon
Regularly making appearances in the Amazon best seller list, the Chime mattress by Ashley is a low-price hybrid. Hybrid mattresses are typically more expensive than their all-foam alternatives but if you want to avoid the body-hugging feel of memory foam, this is a bouncier alternative that won't break the bank. At this price point it probably lacks longevity but with over 20,000 positive reviews it's likely to be a good short term solution for sleep comfort. And with a queen only $237.02 (was $349.99) for Prime members, it's one of the best priced hybrids you can buy today.
User score: ★★★★½ (29,000+ reviews)
10. Best Price 8" Mattress: twin was $146.99 now $89 at Amazon
For shoppers on very tight budgets, this saving from Best Price mattress is almost impossible to beat. At just $89 for an 8" thick twin size mattress, it's ideal for spare rooms, giving your guests a comfy place to sleep — and you can use the money you save to finish the set up with one of the best pillows. The bad news is there's no deal on the 8" queen size but you can get a 10" queen for just $151.99 (was $219.99.)
User score: ★★★★½ (30,000+ reviews)
11. Sleep innovations Marley Hybrid 10" Mattress: twin was $319.99 now $231.18 at Amazon
Cheap mattresses often struggle to maintain support across the mattress but the Marley by Sleep Innovations features a foam edge railing to keep the support sturdy right up to the perimeter. Reviews note it's best for side sleepers, with some customers finding it softens with use — so if it feels too firm at first, give it some time to break in. For Prime Day a queen has been dropped to just $310.65 down from $429.99, which is the lowest price we've seen so far this year.
User score: ★★★★½ (1,000+ reviews)
12. ESHINE Adjustable Bed Frame + 14" Hybrid Mattress: twin XL was $799.99 now $639.99 at Amazon
This Prime Day the best Amazon deals are primarily on cheap mattresses but if you're looking to indulge in your sleep set up there are still savings to browse. Like this deal from ESHINE, which pairs an adjustable bed base with a 14" hybrid mattress. Adjustable bed frames are recommended for those who frequently experience aches and pains, as zero gravity positioning can help reduce pressure on the body. For Prime Day a queen set is down to the lowest price we've seen at just $865.60 (was $1,086) for the set.
User score: ★★★★½ (900+ reviews)
13. Siena Essential 8" Memory Foam Mattress: twin was $148 now $119 at Amazon
Supporting both your sleep and your wallet, the 8" Siena mattress uses the same high quality foams you'll find in the Siena Original (topping this guide as our favorite Prime Day deal), just on a smaller scale. We recommend it for teens and children primarily, but it's also among our favorite mattresses for a college student. And with a queen only $179 (was $279), you'll have room left in the budget for more than just ramen.
User score: ★★★★½ (600+ reviews)
14. Cool Gel Chill Memory Foam Mattress: full was $429.99 now $399.99 at Amazon
You don't need to be a Prime member to take advantage of this sale, which is good news for anyone struggling to sleep in the recent heatwaves. The Cool Gel Chill mattress uses heat-wicking foams to keep you comfortable throughout the night, even when the summer heat is sabotaging your sleep. This mid-range model might not be as chill as the best cooling mattresses we've tested but at just $474.99 for a queen (was $569.99), it's a low cost solution to night sweats.
User score: ★★★★½ (54,000+ reviews)
15. Nectar Memory Foam Mattress: twin was $349 now $282 at Amazon
An older version of the Nectar Classic Memory Foam Mattress above, this version delivers the same exceptional blend of support and cushioning — you can see why we love it in our Nectar Mattress review. If you want better durability and a higher quality finish, go for the new option above. But if you want the best value for money, this model is only $451.06 for a queen (was $649) and comes with a 365-night trial and lifetime warranty.
16. Casper Original Mattress: twin was $895 now $611.50 at Amazon
It's since been replaced by The One mattress in the main Casper line-up but the Original mattress is still around to buy and still a good choice for side sleepers. It impressed us with its body-contouring comfort in our Casper Original mattress review and while you'll pay $1,295 for a queen at the Casper website, this massive Prime deal gets you a queen for $891.50. Plus, you'll get a 100-night sleep trial and free returns.
Today's top mattress deals you wouldn't find on Amazon
Not a Prime member? That doesn't mean you can't invest in your sleep during Prime Day. With many mattress brands and retailers running rival sales (including budget bed favorites like Walmart) there was still ample chance to save. Here are six of the biggest competitor deals we spotted during Prime Day...
1. Saatva Classic Mattress: twin was $1,399 now $1,099 at Saatva
Our Saatva Classic Mattress review team gave this handcrafted mattress full marks in all areas, praising the luxury support, full-body pressure relief and breathable feel. It's available in three firmness levels (soft, medium-firm, firm) and two heights (11.5 inches or 14.5 inches), and this customization gives it a wide appeal — it suits almost every sleep style. You can save $300 on all sizes of the Classic right now by following our links, reducing a queen to $1,799 (was $2,099.) We did spot it for $1,699 in the recent 4th of July sales but we think it will be a while before that deal and returns — and this is an excellent price on a mattress that "revolutionized" our lead testers sleep. Plus, you get a full year's trial, lifetime warranty and free white glove delivery.
2. Helix Midnight Luxe: twin was $1,436 now $1,048.28 at Helix
Named the best mattress for side sleepers by our experienced testing team, the Helix Midnight Luxe offers plush comfort and an indulgent feel. In fact, the lead tester in our Helix Midnight Luxe mattress review has been singing its praises for over a year. In the current Helix mattress sale you can save 27% on the Midnight Luxe using code TOMS27, a big step up from the 20% off sale we're more used to seeing at Helix. A queen is currently $1,751.03 (was $2,398.66) and comes with a 100-night trial and a lifetime warranty.
3. DreamCloud Classic Hybrid Mattress: twin was $419 now $356 at DreamCloud
DreamCloud mattress sales are fairly predictable so we're surprised to see the brand taking on Prime Day with an extra 15% off affordable luxury mattresses. This reduces a queen size DreamCloud Classic Hybrid to $594 (was $699) which is the lowest price we've seen this year. While we haven't had a chance to test this new model, we predict it delivers the same crowd-pleasing comfort we observed in our DreamCloud mattress review — and you have a 365-night trial to test it out, plus a lifetime warranty.
4. Nectar Premier Memory Foam Mattress: twin was 549 now $467 at Nectar
If you're looking for the classic memory foam experience — deep soothing hug, sink-in comfort — that's just what you'll get with the Nectar Premier. One of the best mattresses for side sleepers, it uses high quality foams to relieve pressure where your body pushes against the bed. We described it as "indulgent" in our Nectar Premier Memory Foam Mattress review. With an extra 15% off in a Prime-rivaling sale, a queen is reduced from $949 to $807 and it comes with a 365-night trial and forever warranty.
5. CopperFlex Pro Hybrid Mattress: twin was $932 now $652.40 at Brooklyn Bedding
The CopperFlex mattress promises a luxury feel for shoppers on a mid-range budget and our CopperFlex Pro Hybrid Mattress review team agreed it achieved just that, impressing us with its thick cushioning, cooler surface and enticingly luxurious look. A queen hybrid is currently $932.40 (was $1,332) and is a good choice for anyone who wants a cooling mattress but is working with a tighter budget. A lifetime warranty and 120-night trial are included.
6. Tempur-Pedic Tempur-Adapt Mattress: twin long was $1,699 now $1,189.30 at Tempur-Pedic
Our Tempur-Pedic Tempur-Adapt mattress review team were skeptical this bed could deliver the 'legendary pressure relief' it promised — and they were proved wrong. Pairing the intense cushioning of Tempur Material foam with a supportive base, we love this mattress for back sleeping and it's also great at relieving aches and pains (but be aware, it can sleep hot.) 30% off is an unusually big saving on this premium mattress, reducing a queen to $1,539.30 (was $2,199.) However, while a 10-year warranty is included, there's no sleep trial.
July's Amazon Prime Day mattress deals 2025: FAQs
What is Prime Overnight and can it be used on mattresses?
Prime members have access to Amazon’s speediest delivery service for less, including free two-day delivery on eligible items and access to next day, overnight and even same day delivery in select areas. This fast shipping applies to a number of categories on Amazon and can potentially include mattresses — although these bulky items often have a longer delivery time.
Mattresses sold on Amazon will typically have increased delivery times compared to other products, as the size and weight of each mattress complicates the shipping process.
However, in most cases, you will still receive your mattress within a few days of ordering.
When ordering your mattress on Amazon, look for the estimated delivery time to best understand when your new bed is likely to arrive. We advise unboxing your mattress soon after delivery, so it’s recommended you’re around when your parcel arrives.
July vs October Prime Day mattress deals: Which are better?
The Amazon Prime Day July 2025 sales offered major discounts on budget-friendly beds, a trend we also spotted during Prime Day July 2024. This included some of the lowest prices we'd seen all year on beds such as the Casper Sleep Elements and the Siena Memory Foam Mattress.
That's well-timed for the back to school sales — if you needed a mattress for a college dorm room, there were plenty to find in the Prime Day sales that wouldn't break a student budget.
In the October 2024 Prime Day sales, the mattress deals looked a little different. For a start, we saw bigger savings on mid-range and premium beds, such as Leesa mattresses.
October is often a quiet time for mattress sales, sitting between the Labor Day deals in September and the influx of Black Friday offers in November.
So the October Prime Day mattress deals were well placed for anyone who wanted to invest in their sleep and couldn't wait until November.
We're predicting another Prime Day event in October 2025 so we'll be keeping a close eye on the deals to see if these trends continue — or if the fall sale will once again be a budget bed bonanza.
Is Amazon Prime Day a good time to buy a mattress?
Amazon Prime Day has always been a good time to save on tech but until recently, it's been a footnote in the mattress sales calendar. However, as the Amazon mattress line-up has expanded to include more beds for every budget, the Prime Day mattress sales have also grown in interest.
While Prime Day still can't compete with the deep discounts of Memorial Day and Black Friday — typically the two biggest mattress deals events — the deals are getting better and the offers more expansive.
And as a sidenote, many mattress brands and retailers are also running rival sales to compete with Prime Day. Meaning even those without a Prime membership should start thinking of Prime Day when trying to save on a new bed.
How do I return a mattress to Amazon?
The Amazon mattress returns process can be complex and largely depends on which mattress you have purchased. You can find more information in our explainer on how to return a mattress to Amazon but here's a quick rundown:
Most mattresses sold on Amazon have a 30-100 day return policy, allowing you to return and refund your bed if you're unhappy with the purchase. To do so, contact the Amazon Returns Center to arrange a pick-up.
However, there's a catch: the Amazon returns policy applies to mattresses in their original condition. In other words, still in the box.
If you've opened your mattress only to find it doesn't meet your needs, you can often still return it. However, the return window is typically under 30 days and you're unlikely to claim a full refund.
But to make things more confusing, some brands selling mattresses on Amazon do offer a sleep trial. During this at-home testing period if you decide the mattress isn't right for you, you can return it for a refund. The average sleep trial lasts 100 nights and you will typically need to contact the manufacturer, rather than Amazon, to claim your refund.
So depending on your mattress, the returns policy can change significantly. We recommend closely reading the terms and conditions before making your purchase, to fully understand your rights.
Which mattresses does Amazon sell?
Amazon used to be the land of cheap and cheerful mattresses but that's changed in recent years. The best mattresses on Amazon now include models from some of our top-rated brands, including Helix, Nectar and DreamCloud.
But you can still find plenty of budget mattresses on Amazon, with the bed best sellers often sitting at a lower price point.
Amazon also sells its own range of mattresses and several brands offer 'Amazon exclusive' mattresses. For example, the Kin mattress by Tuft & Needle can only be found on Amazon
