Whether it’s hot summers or hot flashes, the best cooling mattresses will offer unparalleled temperature regulation, helping to keep you comfortably cool all night long. While all of the best mattresses will offer a certain degree of temperature regulation, we have rounded up the mattresses that boast the very latest in specialised cooling technology. 

There’s more than one way to provide outstanding temperature regulation, whether it’s by harnessing the naturally cooling properties of organic materials, or thanks to the inclusion of cutting-edge cooling technology. But which method is best? As a team of certified sleep specialists and mattress testing experts, we are well placed to cut through brands’ lofty cooling claims and help guide you towards the best cooling mattress for you. 

Specialist beds that deliver on their promises to dissipate heat and keep sleepers comfortably cool throughout the night will often command a higher price tag. However, we have carefully considered price as well as performance when compiling this guide. Of course, timing your purchase to coincide with mattress sales and major holidays — like the Memorial Day mattress sales in May — will help you buy your mattress at the best price. But first, here are our top recommendations for this year's best cooling mattresses, as selected by our mattress testers…

Price bracket: Premium
Materials: memory foam, natural latex, foam and innersprings

Reasons to avoid

Might be too firm for lighter bodies
-
Middling edge support

The Casper Wave Hybrid Snow has been discontinued in a huge brand relaunch and has been replaced with a new cooling mattress, the Snow Max Hybrid mattress. We’re in the process of reviewing the Snow Wave Hybrid to see if its new cooling credentials stand up to the original. In the meantime, there's still time to buy the Casper Wave Hybrid Snow in a massive 50% off clearance sale.

The best cooling mattress for most people is the Casper Wave Hybrid Snow. As Casper’s premium mattress, this is a bed that comes packed with cutting edge cooling technology as well as exceptional support. Contouring foam and springs combined with phase-changing, cool-to-the-touch QuickCool cover make the Casper Wave Hybrid Snow a dependable choice for particularly hot sleepers who want to keep cool without compromising on support.

The Casper Wave Hybrid Snow is crafted from six cooling layers; the top three layers aid temperature regulation, with the QuickCool Cover on top that's infused with phase-change material. Next, there's a thin layer of breathable, perforated foam coated in cooling gel, followed by another layer of perforated foam, this time with six heat-wicking bands spaced horizontally across the mattress to pull heat away from your body. 

This is a mattress that combines temperature regulation with outstanding pressure relief, so next up is a memory foam layer which is divided into three zones to provide pressure relief to your shoulders, waist and lower back, and help align your spine. This, along with its 7 out of 10 rating for firmness, makes it a dependable choice for neck and back pain sufferers as well as hot sleepers. 

There’s also low motion transfer, which is great news for couples and restless sleepers — so what are the drawbacks? It only comes in a medium firm. For this price, we would have liked to have seen more customizable firmness options so that it could appeal to a wide range of sleeping styles. Also, as a premium product, it comes at a premium price (an evergreen 30% off sale means that prices start at $2,166.50 for a Twin XL). However, we think the Casper Wave Hybrid Snow a worthwhile investment for those blighted by both back pain and overheating at night.

The Casper Wave Hybrid Snow offers specialist cooling technology and formerly sat at the top of Casper's impressive sleep suite. It has been replaced by the new Snow Max Hybrid mattress in a new brand relaunch, but you can still buy the Casper Wave Hybrid Snow in a huge 50% off clearance sale (for now). This means you can pick up a queen size Wave Hybrid Snow for just $1,753 (was $3,595). It's an incredible price for a specialist cooling mattress - but you'll have to be quick, this sale can't last forever.

Too firm for side sleepers

The 12-inch high Cocoon by Sealy Chill is a reliable cooling mattress with impressive features for the lower price. It's available as an all-foam model and a hybrid – we tested the all-foam version, but as a rule hybrids will always sleep that bit cooler than even the best memory foam mattresses, because the springs create an extra bit of space for air to circulate.

The Cocoon Chill magic begins with a cover designed to remain cool to the touch during sleep. Beneath this are two layers of the brand’s Phase Change Material pressure-relieving memory foam, designed to dissipates body heat while adapting to your unique body shape and supporting your spine in various sleeping positions. It also provides a little of that 'sink-in' feeling but with that all-important spinal support. 

In our tests, we found the Chill comfortable for most sleepers in most positions, although be aware if you're heavier in weight, you might sink through the memory foam layer and find it a bit too firm. The Cocoon Chill cooling mattress has a core layer made up of eight-inch pocketed coils, which will give this model a slightly bouncier feel. There are firmer coils around the perimeter to bolster the edges, meaning you can make use of every inch of your bed space.

The cooling here is excellent for the price. Our reviewers found the Chill to be noticeably better at regulating temperature than any other mid-range foam mattress they'd tested, and one of the most consistently cool mattresses they'd slept on. Note, however, that spending a bit more will yield better chilling features – if you have a slightly bigger budget, a good upgrade would be the Nectar Premier Copper at #5.

Too soft for stomach/back sleepers

The extra features in Nectar's Premier Copper mattress are designed for hot sleepers looking for an effective cooling mattress with a more affordable price. At 14" deep, the Premier Copper delivers big on comfort as well as temperature-regulation. In our tests, the polyethylene-and-copper blend cover and 4" top layer of gel memory foam infused with phase change materials did a great job of wicking away sweat and body heat and regulating sleep temperature, keeping our sleepers comfortably cool during the testing period. We found the top cover was cool to the touch, although not as dramatically so as the pricier GhostBed (#4) or Casper (#8). 

Rated a 6 out of 10 on the firmness scale, the Nectar's Premier Copper cooling mattress is best suited to side sleepers. The surface adapts nicely to the contours of the body in this position, especially around the shoulders and head, reducing pressure and keeping the spine comfortably aligned. Stomach and back sleepers will likely find it a little unsupportive though, and would be better with something firmer. 

The Premier Copper is more of an investment than the uber-popular original model (read about that in our Nectar mattress review), Note too that this mattress is the only model in our ranking to come with a full 365-night trial, which means you can try it out in every season before committing to keeping it. There's a forever warranty for added peace of mind, too.

Best cooling mattress for joint pain

Height: 9.25"
Trial: 100 nights
Warranty: 10 years
Price bracket: Mid / upper-mid
Materials: GelFlex grid, foams

Reasons to buy

Breathable, with effective cooling

Relieves pressure on the back 
+
Isolates motion well

Reasons to avoid

-
Edge support could be stronger
-
Relatively thin

For something a little different, check out the Purple Original. Like all of this brand's beds, the original features a layer of 'GelFlex Grid'. This stretchy gel grid sits at the top of the mattress, and will contour to your shape for custom support. Thanks to the open structure, it won't trap body heat – which is an issue with many foams. In our review, we found the grid was temperature-neutral, and worked to ensure the mattress stayed at a cool, comfortable temperature all night long.

There's a slightly unusual sleep feel here: the grid feels squishy when pressed, but firm when you're lying down on it, with extra support seeming to concentrate exactly where it's needed, under the back and legs. It's much more responsive than traditional memory foam, too, and will spring back into shape immediately when pressure is removed. We found it super comfortable in all positions, but especially so for side and back sleeping.

This mattress excels when it comes to pressure relief (our testers describe it as giving a kind of floating sensation), and we rank it amongst the best mattress in a box models around for anyone with hip or back pain.  The grid cushions the joints comfortably, while still offering the support required to keep everything aligned properly. Do note that it's the thinnest option in our list though, clocking in under 10". That will make changing the sheets easier, but you won't get the same luxe feeling as a chunkier option. 

Price-wise, we're in the upper-mid price bracket here, but how much you'll pay does depend on when you buy. The best Purple mattress sales and deals knock $200 or more off, but it's hard to predict when they'll appear. The Nectar model at #5 sits in a similar price bracket, if you prefer the sink-in feel of traditional memory foam.
