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. The best cooling mattresses feel cool as you fall asleep and dissipate heat efficiently all night, so you don't feel your mattress gradually getting warmer and warmer. Even if you don't consider yourself a hot sleeper, a mattress with strong cooling can help make summer heat waves more comfortable.
While all-foam and particularly memory foam mattresses have a reputation for retaining heat, all types of mattresses can be suitable (or unsuitable) for hot sleepers, depending on their design and specific materials. Cooling performance is the most important factor, but if you often sleep hot, you might also prefer mattresses that aren't too enveloping, as those can increase your perception of heat by making you feel hugged or constricted.
We've tested more than 55 mattresses, 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, and our picks include options that are suitable for a range of weight categories and sleeping positions.

We've recently started testing mattresses. We purchase each unit independently from major retailers, just like you, to keep our reviews free of manufacturer influence. Each mattress undergoes the same tests to measure objective data on characteristics like firmness, cooling, and motion isolation, so you can easily compare 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
Cooling9.9Energy Transferred Over 1st Hour121 kJEnergy Transferred Over 8 Hours318 kJFirmness LevelMedium (45 Pa/mm)Side Sleeping7.1Back Sleeping6.8Stomach Sleeping6.7See all our test resultsLongevity7.4The Purple RestorePlus Hybrid is the best cooling mattress we've tested. If cooling is your top priority, or you can't find a mattress that feels cool enough, it's hard to do better than this mattress, which boasts off-the-charts cooling performance. This Medium mattress works best for lighter back and stomach sleepers, as well as side sleepers in the average and heavier weight categories. This mattress's unusual grid-shaped comfort layer helps it dissipate heat faster than most mattresses. The mattress feels cool when you first get into bed and continues to move heat away from you very efficiently all night, and overall, it's worth considering if you're looking for the best cooling you can get.
It's bouncy and responsive, so it feels easy to move around on, and the grid layer provides high contouring, which cushions pressure points like your arm and shoulder if you're a side sleeper. However, keep in mind that you can feel the grid under the mattress cover, so you should expect it to feel different from most other mattresses with foam or quilted upper layers. Otherwise, its great motion dissipation makes it suitable for sleeping with a partner, and its solid edges let you comfortably sit or sleep on the edge of the bed.

Best Upper Mid-Range Cooling Mattress
Cooling8.6Energy Transferred Over 1st Hour67 kJEnergy Transferred Over 8 Hours187 kJFirmness LevelFirm (60 Pa/mm)Side Sleeping7.4Back Sleeping7.6Stomach Sleeping7.7See all our test resultsLongevity8.3The Saatva Latex Hybrid is a very cooling upper mid-range mattress with better performance for many back and stomach sleepers. While it's not as extremely cooling as the Purple RestorePlus Hybrid, it's still one of the most cooling mattresses we've tested. It's also more versatile, with enough support for most back and stomach sleepers and good pressure relief for average-weight and heavier side sleepers. It's a more conventional mattress than the Purple, without any unusual design quirks or cooling features, and it instead uses breathable materials that help with cooling. Pocket coils allow 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.
While you won't sink into or be enveloped by this mattress, its comfort layers are particularly contouring, which helps it offer good pressure relief despite the firmer feel. Otherwise, it performs well overall. It's very durable, so it resists sagging and permanent indentations for longer. It also offers good motion isolation, although if you sleep lightly with a partner who tosses and turns, other mattresses do a better job of reducing the motion you feel. All in all, though, it's a solid option for lasting cooling.

Best Mid-Range Cooling Mattress
Cooling9.7Energy Transferred Over 1st Hour109 kJEnergy Transferred Over 8 Hours218 kJFirmness LevelMedium-Firm (51 Pa/mm)Side Sleeping6.3Back Sleeping6.6Stomach Sleeping6.6See all our test resultsLongevity7.1If you want the best cooling possible without spending high-end prices, consider the mid-range Purple Mattress. This Medium-Firm mattress has an all-foam design, but its comfort layer is made of the same Gel-Flex grid as the Purple RestorePlus Hybrid's. While it's not the most supportive option, it works well for average-weight and heavier side sleepers, as well as lighter back and stomach sleepers. And, although it's not quite as cooling as the pricier RestorePlus, it comes in a very close second. The mattress feels cooler than the Saatva Latex Hybrid when you first get into bed and, unlike many all-foam mattresses, continues to dissipate heat very efficiently overnight, making a great option for people who often or always sleep hot.
The responsive, bouncy sleeping surface makes it feel easy to move around on, so you won't feel tightly hugged or enveloped, although again, you can feel the outline of the grid under the mattress cover, which requires some getting used to. If you're also worried about your partner's movements disturbing your sleep, it's worth noting that its motion isolation performance is good but not great. Motion dissipates quickly and doesn't travel all over the mattress, but you'll feel most movements briefly.

Best Budget Cooling Mattress
Cooling8.3Energy Transferred Over 1st Hour63 kJEnergy Transferred Over 8 Hours179 kJFirmness LevelMedium-Plush (41 Pa/mm)Side Sleeping7.0Back Sleeping6.8Stomach Sleeping6.7See all our test resultsLongevity8.3If you want a less expensive option and aren't sure you'll like the feel of the Purple Mattress's grid comfort layer, consider the budget-friendly Boring Hybrid. This mattress has a softer Medium-Plush feel and offers great performance for average-weight and heavier side sleepers, as well as lighter back and stomach sleepers. You'll also sink into it more overall than the Purple Mattress, making it a good option if cooling is a concern, but you also prefer plusher, more enveloping mattresses. It's not quite as cooling as the previous picks, but it's still impressively cooling and suitable for hot sleepers. The mattress does a particularly good job of dissipating heat as the night goes on, so it's a good choice if you often wake up later in the night feeling overheated, since it won't gradually get warmer and warmer as you sleep.
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, which will help keep it comfortable and supportive for longer. Also, unlike some of the previous picks, its motion dissipation is excellent, so you won't feel most of your partner's movements, making it a good option for couples.

Best Cheap Cooling Mattress
Cooling8.3Energy Transferred Over 1st Hour59 kJEnergy Transferred Over 8 Hours183 kJFirmness LevelMedium-Firm (54 Pa/mm)Side Sleeping6.7Back Sleeping7.3Stomach Sleeping7.5See all our test resultsLongevity6.0While some cheap mattresses trap a lot of heat, you don't necessarily have to avoid inexpensive options if you're a hot sleeper. The Allswell Hybrid is a lower-end, Medium-Firm mattress that offers great cooling similar to the Boring Hybrid, plus solid overall performance for the price. It's not as comfortable for most side sleepers because of its firmer feel, but its decent support for people in a range of weight categories makes it suitable for most back and stomach sleepers. While it doesn't have breathable latex or a grid-shaped comfort layer that whisks away heat, its straightforward design, with pocket coils for support and relatively thin foam layers, helps it move heat away and keep you cool all night. Some mattresses feel cooler when you first get into bed, but it offers very strong cooling over several hours, so you won't wake up later on boiling hot.
You won't sink into the mattress very far, but a memory foam layer adds some contouring, which helps cushion pressure points like your hips and shoulders when sleeping on your back. It's quite bouncy and responsive, making it easy to change sleeping positions. This mattress also works well for couples, since its excellent motion dissipation means you won't feel most movements, and its very sturdy sides help make it comfortable to sleep near the side of the bed, so you have more room to share.
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 low responsiveness makes 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.

Casper Snow (Canadian Version):
The Casper Snow (Canadian Version) is a high-end hybrid mattress with fantastic cooling. It's still not as cooling as the Purple RestorePlus Hybrid, but it performs better for average-weight and lighter side sleepers. Unlike the U.S. version of the mattress, it has polyfoam upper comfort layers that give it a responsive feel, so you're less likely to feel stuck in place.
See our review -
Tuft and Needle Mint:
The Tuft and Needle Mint is a mid-range mattress that you may prefer to the Purple Mattress if you're a side sleeper, particularly in the lighter weight category. While it's not quite as cooling as that mattress, its performance is good enough to keep hot sleepers comfortable, and it offers much better pressure relief for lighter side sleepers.

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.
