If you're after Amazon Prime Day mattress deals, you're too late. But don't let that get you down; while Amazon Prime Day deals have been great for all sorts of items, in terms of impressive mattress discounts it's all been a bit limited.

Over the past couple of days we've seen a few really good deals from sleep brands such as Casper and Tempur-Pedic in the US, while Simba and Emma came up with the goods in the UK. But while Prime Day's done and dusted, mattress sales are an ongoing thing and there are still plenty of opportunities to save on a new bed.

Below you'll find the top deals we spotted over the Prime Day period, although the chances of the listed discounts still being available are slim, at least on Amazon; most prices will have reverted to normal levels more or less on the stroke of midnight in your part of the world. If you're buying one of the best mattresses direct from the manufacturer, though, you'll likely find the discounted price is still live, or at least something pretty close to it.

So, whether you’re looking for a great memory foam mattress, the best hybrid mattress, or simply the best mattress on Amazon, there are still plenty of opportunities to save money.

This year's Prime Day mattress deals

US Prime Day mattress deals - Amazon

1. Casper Element Mattress: $395 $296.25 at AmazonSave up to $199 -

1. Casper Element Mattress: was $395 now from $296.25 at Amazon
Save up to $199 - You can't easily buy the Element direct from Casper any more, but its cheapest memory foam mattress is still available on Amazon, and it has 25% off right now. Despite its low price, the Casper Element packs in the same AirScape cooling tech found in its more expensive siblings. A queen size is discounted to $446.23 (was $595), and it’s a good choice for restless sleepers who usually struggle to get comfortable in bed.

2. Casper Original mattress: $895 $626.50 at Amazon
Lowest price

2. Casper Original mattress: was $895 now from $626.50 at Amazon
Lowest price
- Now's the time to head to Amazon if you're after a Casper mattress; unlike the Element above, the Original is on sale at Casper right now, with a 20% discount. At Amazon, however, there's a whole 30% off the Original, bringing the price of this high-end all-foam mattress down to $906.50 in a queen size (at Casper it'll cost you $1,036). We've rarely seen the price of the Original this low, so get on this one before Amazon Prime Day deals come to an end.

3. Tempur-Adapt + Cooling Topper: $499 $237 at Amazon
Save big on a queen

3. Tempur-Adapt + Cooling Topper: was $499 now from $237 at Amazon
Save big on a queen
- We've just spotted an epic deal on the most advanced version of the popular (but expensive) Tempur-Adapt topper. The Tempur-Adapt + Cooling has a washable cooling cover that promises to keep you up to 8° cooler, and it's an $80 upgrade that brings the price up to $415.20 on the Tempur site, and that's with a discount applied. However there's 52% off the queen size on Amazon for Prime Day, so it'll cost you just $237.49. And yes, we know, at Tempur you get a free pillow and sleep mask included, but get this: you can buy a topper + pillow bundle for $374.19 at Amazon, which is still $41 cheaper. (We'd just go for the option without the pillow).

4. Zinus Green Tea 12” Mattress: $219 $209 at Amazon

4. Zinus Green Tea 12” Mattress: was $219 now from $209 at Amazon
The Zinus Green Tea Memory Foam mattress is a popular option on Amazon, and Prime Day is the perfect option to get the best price on it. It uses three layers of foam to support and cradle your body, relieving pressure on your back and hips. The infusion of green tea keeps the entire mattress fresher and cleaner. Right now a 12-inch queen size will cost you $329.

5. Nectar Mattress: $499 $359 at Nectar SleepSave up to $699 -

5. Nectar Mattress: was $499 now from $359 at Nectar Sleep
Save up to $699 - The Nectar Mattress is on sale at Amazon, and at the same price too, and while we used to advise buying at Nectar because you'd a set of free bedding included, that's no longer an option. Instead you'll get a discount on a bedding set, and if you already have your own bedding then you're probably not really interested in that anyway. As a matter of course, however, we'd suggest buying from the manufacturer, but wherever you buy you'll get 365-night trial and forever warranty. Bear in mind though that you may be able to save more with Nectar coupon codes.

6. DreamCloud Mattress: $799 $599 at DreamCloudSave up to $880 -

6. DreamCloud Mattress: was $799 now from $599 at DreamCloud
Save up to $880 - In terms of price there's no real difference between buying DreamCloud's luxury hybrid mattress from Amazon and buying it direct from DreamCloud. They're both selling at identical prices, so a queen size will cost you $799 wherever you buy. However! Amazon says that this price is an 11% discount, while at DreamCloud that's a massive 40% off, which has us just a little confused. We’d recommend the DreamCloud over the Nectar Mattress if you sleep hot and have back pain. You’ll get a 365-night trial on this one too and a forever warranty. It’s superb value for a premium hybrid; get all the facts in our DreamCloud mattress review.

7. Lucid 10 Inch Hybrid Mattress with Bamboo: $289.99 $160.65 at AmazonSave up to $40 -

7. Lucid 10 Inch Hybrid Mattress with Bamboo: was $289.99 now from $160.65 at Amazon
Save up to $40 - This is a good Prime Day mattress deal if you experience night sweats, hot flashes (flushes) or overheating during sleep and need a mattress that not only cools, but wicks away moisture too. Lucid’s 10” Hybrid ticks all of those boxes thanks to a combination of bamboo, charcoal and aloe vera-infused memory foam to naturally absorb sweat, body oils and odors. As a medium-firm mattress, it will suit most body types and sleep positions too. The twin size is currently reduced by 45%, and the queen is 15% off at $365.49, which is a decent price for 10” hybrid made with some natural materials, and it may come down for Prime Day.

8. Nod by Tuft & Needle Mattress: $349 $279.20 at AmazonSave up to $120

8. Nod by Tuft & Needle Mattress: was $349 now from $279.20 at Amazon
Save up to $120 - Shopping the Prime Day mattress deals for a cheap bed to upgrade your guest room? For occasional use you can’t go wrong with Tuft & Needle’s basic bed-in-a-box, The Nod. It’s made from CertiPUR-US toxin-free foams and comes with a 10-year warranty, which is generous for a cheap mattress, and there's 20% off the 8-inch model for Prime Day. A queen size is $100 off at $399.20, making it very competitively priced if you want a slimmer memory foam bed than the Zinus 12”. Because it’s slimmer it will feel firmer, making it a good pick for back and stomach sleepers in particular.

9. Linenspa 10 Inch Hybrid Mattress: $199.99 £148.79 at Amazon
Up to 29% off

9. Linenspa 10 Inch Hybrid Mattress: was $199.99 now from £148.79 at Amazon
Up to 29% off
- Linenspa's 10-inch hybrid is one of the best cheap mattresses around, and there are some great discounts to be had on Prime Day. The biggest saving is 34% off a full size, while there's 25% off a queen size, bringing the price down to $239.99. It's a good option if you're on a tight budget, or if you're looking for a kid's bed or something to furnish a spare room; our review of the 8-inch Linenspa Memory Foam Hybrid mattress can put you in the picture.

10. Casper Waterproof Mattress Protector: $89 $62.30 at Amazon
Beat Casper's discount

10. Casper Waterproof Mattress Protector: was $89 now from $62.30 at Amazon
Beat Casper's discount
- It always pays to get one of the best mattress protectors to go with a new bed, and this waterproof protector is in the Prime Day sales at a lower price than you'll pay at Casper. There's 30% off for Prime Day, while on the Casper site you'll only get 20% off; that means this breathable and waterproof protector made with bamboo fabric can be yours in a queen size for just $69.30, down from $99.

11. Linenspa 2 Inch Memory Foam Mattress Topper: $39.99 $27.99 at Amazon
30% off all sizes

11. Linenspa 2 Inch Memory Foam Mattress Topper: was $39.99 now from $27.99 at Amazon
30% off all sizes
- For an easy and affordable way to give an old mattress a new lease of life, this gel-infused memory foam topper from Linenspa is a cheap but effective solution. It's as basic as they come: a two-inch sheet of foam without even a cover, so you'll need to pair it with a mattress protector or similar, but at $41.99 for a queen size it's the cheapest we've seen it for a very long time, and phenomenal value.

12. Casper Down Pillow: $139 $111.20 at Amazon
Best pillow, best price

12. Casper Down Pillow: was $139 now from $111.20 at Amazon
Best pillow, best price
- We rate the Casper Down Pillow as the best pillow you can buy right now, and if you buy it at Amazon during Prime Day you'll beat Casper's own pricing. There's 20% off the Down Pillow at Casper, but if you choose a king size two pack at Amazon you'll get 26% taken off. That drops the price from $322 to $237.50, and while you may feel that's a lot for a pair of pillows, we think it's a very fair price for two fluffy and supportive pillows that are suitable for all sleeping positions.

US Prime Day mattress deals - non-Amazon

1. Saatva Classic Mattress:  $895 at SaatvaUp to $350 off 

1. Saatva Classic Mattress: was $1,095 now from $895 at Saatva
Up to $350 off - Saatva's not on Amazon but it's running its own Prime Day event, with between $200 and $500 off when you spend over $1,000. It's pretty standard in terms of Saatva sales, and it means you can buy the Saatva Classic in a queen size for $1,695, which has been the average price for the Classic so far this year. You'll get a 1-year trial, lifetime warranty, and complimentary white glove delivery. Check out our Saatva Classic mattress review to learn why we rate this one so highly.

2. Cocoon by Sealy Chill Mattress: $619 $374 at Cocoon by SealySave up to $764

2. Cocoon by Sealy Chill Mattress: was $619 now from $374 at Cocoon by Sealy
Save up to $764 - If you have a bit more budget and want a cooler bed, we’d recommend the Cocoon by Sealy Chill Memory Foam Mattress. You won’t find a better Prime Day deal on this than the brand’s own offer - $699 for a queen size cooling mattress, and you get $179 worth of free cooling bedding ($199 worth with larger sizes). Even better, use the EXTRA25 code to knock $25 off at the checkout; that way a queen is just $674. The Chill sports a cover made from phase change material that constantly seeks out and dissipates heat so that it doesn’t pool beneath you. 

3. Helix Midnight Mattress: $936 $702.40 at Helix
Lowest price ever

3. Helix Midnight Mattress: was $936 now from $702.40 at Helix
Lowest price ever
- This mid-market hybrid is on the softer side, making it a great choice for side sleepers who need pressure relief on their shoulder and hips. In our Helix Midnight review, we were also impressed with this mattress' temperature regulation properties and ability to isolate motion (so you won't be disturbed by a partner moving around). Buy one in the current Helix mattress sale and you'll get 25% off; this means you'll get a queen for $999, which is the cheapest we've ever seen it for, with two free pillows along with a 100-night trial and a 10-year limited warranty. 

4. Avocado Latex Mattress: 2,399$1,679 at Avocado

4. Avocado Latex Mattress: was $2,399 now from $1,679 at Avocado
Latex mattresses don't come cheap but if you want an eco-friendly alternative to memory foam that has a lot more bounce, this is an option worth grabbing. Avocado is clearing stock of its Latex Mattress with a 30% discount, which is as good as it gets with this particular brand. This hand-crafted organic mattress is great for comfort and motion isolation, with just the right amount of bounce. It's on sale for $2,099 in a queen size, but you'd better move fast as once it's gone, it's gone.

UK Prime Day mattress deals - Amazon

1. Simba Hybrid Pro: £1,599 £879.45 at Simba
Simba sale-beating price

1. Simba Hybrid Pro: was £1,599 now from £879.45 at Simba
Simba sale-beating price
- You'll find the Simba Hybrid Pro second in our UK best mattress roundup, and right now it's actually cheaper to buy it from Amazon than direct from Simba. The current Simba sale takes 40% off the Hybrid Pro, but for Prime Day, there's a sweet 40% off at Amazon, bringing the price of a double (the single appears to be sold out) down to £879.45 (you'll pay £959.40 at Simba). We should point out that there's no mention of a free mattress protector like you get when you buy from Simba, and also that this is an older version of the Hybrid Pro with a Simbatex foam base, while the version on sale at Simba has a new sprung base that makes it less heavy and more environmentally-friendly. It's still a solid buy, though, but don't hang about; Amazon claims that there are only 12 doubles left in stock.

2. Emma Original mattress: £446.47 £339.50 at Emma
Up to 30% off

2. Emma Original mattress: was £446.47 now from £339.50 at Emma
Up to 30% off
- It's not often that we can say this, but if you want the lowest price for the Emma Original today then you're best off at Amazon (at least if you want a double size or bigger).Today's Prime Day pricing beats Emma hands-down: a double for £339.50 is £39.70 cheaper, a king size is £78 less at £350.20, while a super king is a whole 20p cheaper at £499. These are (mostly) excellent prices on a leading memory foam mattress that delivers a gentle body-hug and is comfortable and supportive in most sleeping positions. Best of all you'll get the same 200-night trial and 10-year warranty that you'd get buying at Emma.

3. Simba Hybrid Mattress: £799 £439.45 at Amazon
Cheaper than at Simba

3. Simba Hybrid Mattress: was £799 now from £439.45 at Amazon
Cheaper than at Simba
- There's 40% off the Simba Hybrid when you buy direct, but at Amazon you'll find a Prime Day deal that takes 45% off, which means a double will cost you £593.45, which is over £50 cheaper than Simba's price. That's great value for its standard hybrid; as with the the Hybrid Pro above we should point out  that it's an older version with a foam base rather than a sprung core, but for this price we'd probably overlook that factor.

4. Zinus Green Tea Memory Foam mattress: £219.99 £212.55 at Amazon
Up to 8% off

4. Zinus Green Tea Memory Foam mattress: was £219.99 now from £212.55 at Amazon
Up to 8% off
- If you absolutely insist on going to Amazon to find a Prime Day mattress deal, we'd suggest you take a look at this reliable foam option from Zinus. Its Green Tea Memory Foam mattress scrapes into our US best mattress guide as a budget option, and we think it's a good choice if you need a bed for a spare room. It features 6cm of green tea-infused memory foam and a seven-zoned support system, and if you choose a double size there's 8% off, bringing the price down to £277.26.

2. REM-Fit 500 Ortho Hybrid mattress:  £439.45 at REM-Fit45% off + free pillows

Where to find 2023’s best Prime Day mattress deals

As you can see from the above offers, Amazon isn’t always the place to shop if you want the best Prime Day mattress deals. Manufacturers are very generous with the free gifts they offer, and that can really increase your value for money. 

Dedicated mattress retailers such as Mattress Firm are also more agile during big sales events and can undercut even Amazon on certain brands - especially past season stock. 

Prime Day is also a good time to save on the best pillows for all sleepers, as well as the best mattress protectors for safeguarding your bed from spills, stains and germs.
