Tossing and turning because it's too hot to fall asleep or waking up overheated in the middle of the night can make even the most comfortable mattress a nightmare. Even if you don't consider yourself a hot sleeper, it's crucial to find a mattress that transfers enough heat away from your body to maintain a comfortable temperature. If you live in a hot climate or often find yourself waking up because of the heat, it's even more important.
Luckily, we've tested more than 40 mattresses using a standardized test bench, and below you'll find our picks for the best cooling mattresses. We've taken into account how well they transfer heat during the first hour after you lie down and throughout the rest of the night, but we've also considered how well the mattress performs overall.
If you're wondering about the wider mattress market, check out our picks for the best mattresses overall. Or, if you need some mattress shopping tips, see our mattress buying guide or our rundown of the different mattress types.
Quick Look
We've recently started testing mattresses. We independently purchase each unit from major retailers, just like you, to keep our reviews free from manufacturer influence. Each mattress goes through the same tests to measure objective data for characteristics like firmness, cooling, and motion isolation, so you can easily compare the results. Since we buy all our mattresses, we can tear them down layer by layer and isolate the mechanical properties of every component: quilted tops, foams, coils, and any special materials.

Best Cooling Mattress
Energy Transferred Over 1st Hour121 kJEnergy Transferred Over 8 Hours318 kJFirmness LevelMedium (45 Pa/mm)Cooling10Longevity7.4Side Sleeping7.2Back Sleeping6.8See all our test resultsStomach Sleeping6.7The Purple RestorePlus Hybrid is the best cooling mattress we've tested. If cooling is your biggest priority, it's hard to do better than this mattress, which boasts an off-the-charts cooling performance. Its 'Gel-Flex Grid' comfort layer, a waffle-shaped layer with a responsive feel, helps dissipate heat, as does its pocket coil support layer. The mattress feels cool when you first get into bed and continues to move heat away from you very efficiently all night, making it a great option for hot sleepers.
This 'Medium' mattress is best suited for lighter back and stomach sleepers. It's also suitable for average-weight and heavier side sleepers, although you might prefer a more supportive mattress. It's bouncy and responsive, so it feels easy to move around on, and its comfort layer provides high contouring, which helps with pressure relief without creating an enveloping feel. Its great motion dissipation makes it a good option for sleeping with a partner, as well.

Best Upper Mid-Range Cooling Mattress
Energy Transferred Over 1st Hour67 kJEnergy Transferred Over 8 Hours187 kJFirmness LevelFirm (60 Pa/mm)Cooling8.6Longevity8.3Side Sleeping7.4Back Sleeping7.6See all our test resultsStomach Sleeping7.7The best mattress for hot sleepers in the upper mid-range is the Saatva Latex Hybrid. This mattress's design helps it provide excellent cooling: a layer of pocket coils allows heat to dissipate more quickly through the support layer, aerated latex improves airflow within the comfort layer, and wool helps regulate temperature and moisture, so you don't wake up sweaty. Together, they keep you cool after you first lie down and provide even more effective cooling through the rest of the night.
This firm mattress offers better support than the Purple RestorePlus Hybrid. It's a good choice for average back and stomach sleepers and offers enough support for heavier back sleepers as well. It's a good option for many side sleepers, although lighter people will need a plusher mattress. It provides good motion isolation, which helps you sleep peacefully with a partner. It's also a very durable mattress, so you can expect it to resist sagging or forming permanent indents for longer than other options. All in all, it's a solid option for lasting cooling.

Best Mid-Range Cooling Mattress

This all-foam mattress's comfort layer is made of the same Gel-Flex material as the Purple RestorePlus Hybrid's. While its foam support layer may hold onto more heat than that mattress's coil layer, it's still an exceptionally cooling mattress. This 'Medium-Firm' mattress offers great support for lighter people, making it a good option for back and stomach sleeping. While it doesn't offer enough pressure relief for lighter side sleepers, it's also a good option for side sleepers in the average and heavier weight categories.
Its responsive, bouncy feel makes it feel easy to move around on, despite its all-foam design. It's also decently durable, since its polyfoam layers are made of good-quality foam. While its motion dissipation isn't great, it still offers a good performance for sleeping with a partner. While it offers good edge support, if you need very sturdy edges for getting in and out of bed, it's not ideal.

Best Budget Cooling Mattress
Energy Transferred Over 1st Hour63 kJEnergy Transferred Over 8 Hours179 kJFirmness LevelMedium-Plush (41 Pa/mm)Cooling8.3Longevity8.3Side Sleeping7.0Back Sleeping6.8See all our test resultsStomach Sleeping6.7If you're looking for a budget-friendly mattress with great cooling, consider the Boring Hybrid mattress. While it doesn't match the Purple Mattress's fantastic cooling, it's cooling enough for hot sleepers. It does a particularly good job of dissipating heat over an eight-hour night, so it's a good choice if you often wake up later in the night feeling overheated. This mattress also stands out for its durability: its foam layers are all made of dense, high-quality foam that should resist showing signs of wear for longer compared with lower-quality foam.
Despite its 'Medium-Plush' feel, it doesn't offer enough pressure relief for lighter side sleepers. However, it's a good option for side sleepers in the average and heavier weight categories. It also offers good support for lighter people, making it a good option for lighter back and stomach sleepers. Its excellent motion dissipation means you won't feel every move your partner makes, and it has very sturdy edges, so you can comfortably sleep or sit on the side of the bed.

Best Cheap Cooling Mattress
Energy Transferred Over 1st Hour56 kJEnergy Transferred Over 8 Hours169 kJFirmness LevelMedium-Firm (53 Pa/mm)Cooling7.8Longevity2.8Side Sleeping6.7Back Sleeping6.8See all our test resultsStomach Sleeping6.8The Beautyrest Silver BRS900 is the best cheap cooling mattress we've tested. This mattress's cooling performance isn't quite good enough for persistently hot sleepers, but unlike some other inexpensive mattresses, it's cooling enough for most people and won't create an issue if you don't generally sleep hot. This 'Medium-Firm' mattress is best for side sleepers in the heavier weight category, and it also offers decent support for lighter back and stomach sleepers.
Its contouring upper comfort layers help with pressure relief, but you won't sink very deeply, so you feel like you're sleeping 'on' and not 'in' it. It's also bouncy and responsive, so it feels easy to move around on. However, its motion dissipation is only decent, so you'll feel most movements all over the mattress, although they dissipate quickly, which makes motion less likely to wake you. Unfortunately, it's not as durable as the previous picks. It uses lower-density and lower-quality foam, which is more prone to forming permanent indentations sooner.
Notable Mentions
-
Casper Snow:
The Casper Snow offers excellent cooling, and unlike the Purple RestorePlus Hybrid, it has a plush enough feel for most side sleepers, including lighter side sleepers. Its slow-moving comfort layers make it more difficult to move around in your sleep, but if you like the feel of memory foam, it's a versatile option for hot sleepers.

Sleep On Latex Pure Green Organic:
The Sleep On Latex Pure Green Organic is an all-latex foam model with an excellent all-around performance. It's not quite as cooling as the Saatva Latex Hybrid, but it still transfers heat away efficiently enough for hot sleepers. However, it's worth noting that it's a very firm mattress, so it's best suited for back and stomach sleepers who prefer a very supportive mattress.

Tuft and Needle Mint:
The Tuft and Needle Mint is an upper mid-range mattress that you may prefer to the Saatva Latex Hybrid if you're a side sleeper, particularly in the lighter weight category. While it's not quite as cooling as the Saatva, its performance is good enough to keep hot sleepers comfortable.

FAQs
What makes a mattress cooling?
While any type of mattress can help keep you cool, hybrids are often (though not always!) the most cooling, thanks to their airy spring support layers. Foam models tend to trap more heat, and memory foam is usually the warmest, whether it's in an all-foam, hybrid, or innerspring design. These mattresses' dense structure and body-hugging feel work against its cooling performance, limiting airflow and trapping heat. To counter this, many manufacturers incorporate cooling features, such as cooling fibers or 'phase change materials' that absorb and release heat.
What materials are more cooling?
Latex foam doesn't hug the body as closely and has an open-cell structure, which makes it more breathable. You'll often find the material paired with wool, which helps regulate temperature by wicking moisture and dissipating excess heat; together, they tend to perform well in terms of cooling. While not every material will work for every sleeper, understanding how each layer affects cooling, comfort, and support can go a long way toward finding a mattress that's right for you.
