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 70 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.
You can read more about how mattress design affects cooling in our comparison of hybrid and memory foam mattresses. Natural materials like wool and latex often help with cooling, so you might be interested in the best latex or best organic mattresses.
We've tested over 70 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
Side Sleeping7.1Back Sleeping6.8Stomach Sleeping6.7Cooling9.9Longevity7.4Energy Transferred Over 1st Hour:121 kJEnergy Transferred Over 8 Hours:318 kJSee all our test resultsFirmness Level:Medium (45 Pa/mm)Pick if: Sleeping hot is a persistent issue for you and most mattresses aren't cooling enough.
Skip if: You're an average/heavier back or stomach sleeper, or a lighter side sleeper.The 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. This Medium hybrid offers an impressive performance for many side sleepers, while its unusual grid-shaped comfort layer helps it dissipate heat faster than most mattresses. We found it has a very cooling feel when you first get into bed and continues to move heat away from you very efficiently all night, so overall, it's a great option if you want the coolest mattress possible.
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. 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. However, we noticed 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. This design also doesn't provide the best performance for lighter side sleepers, who won't sink into the layers below the grid and won't get much pressure relief.

Best Upper Mid-Range Cooling Mattress
Side Sleeping8.3Back Sleeping8.5Stomach Sleeping8.6Cooling8.9Longevity5.3Energy Transferred Over 1st Hour:71 kJEnergy Transferred Over 8 Hours:198 kJSee all our test resultsFirmness Level:Medium (47 Pa/mm)Pick if: You want a cooling mattress with an enveloping, hugging feel.
Skip if: You want a more durable mattress or strong edge support is a priority.If you need strong cooling but prefer a less expensive choice, you might prefer the Casper Snow. This Medium mattress's memory foam comfort layers are plush and contouring, so you'll feel like you're sleeping 'in' instead of 'on' your mattress. It doesn't have the same exceptional cooling performance as the Purple RestorePlus Hybrid, but unlike many memory foam models, its excellent cooling makes it well-suited for hot sleepers. Cooling features, including heat-conducting aluminum-graphite bands that were visible when we cut open the mattress, help it dissipate heat efficiently overnight, so you won't feel your mattress heating up as you sleep.
This mattress's enveloping feel helps it offer better pressure relief overall, so it's a comfortable option for a range of side sleepers, including people in the lighter weight category. It's also supportive enough for a range of back and stomach sleepers, so it's a great option for combination sleepers or couples with different preferences. However, it's worth noting that some people will feel constricted by its slow-moving comfort layers. Also, it only includes lower-quality foam, so it's not as durable as the previous pick and may show signs of wear sooner.

Best Mid-Range Cooling Mattress
Side Sleeping6.3Back Sleeping6.6Stomach Sleeping6.6Cooling9.7Longevity7.1Energy Transferred Over 1st Hour:109 kJEnergy Transferred Over 8 Hours:218 kJSee all our test resultsFirmness Level:Medium-Firm (51 Pa/mm)Pick if: You're a lighter back/stomach sleeper or a heavier side sleeper and want fantastic cooling at a lower price.
Skip if: You're average-weight, a lighter side sleeper or heavier back/stomach sleeper.If 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. Like that mattress, it's suitable for heavier side sleepers and lighter back/stomach sleepers, although its performance for average-weight side sleepers isn't as good. And, although it's not quite as cooling as the pricier Purple, we measured cooling that's nearly as good. The mattress feels cool when you first get into bed and, unlike many all-foam mattresses, continues to dissipate heat very efficiently overnight, making it 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
Side Sleeping7.7Back Sleeping7.0Stomach Sleeping6.8Cooling8.7Longevity6.1Energy Transferred Over 1st Hour:73 kJEnergy Transferred Over 8 Hours:186 kJSee all our test resultsFirmness Level:Medium-Plush (40 Pa/mm)Pick if: You're a side sleeper and want strong motion isolation and cooling.
Skip if: You're a lighter side sleeper or want strong edge support.If you want a budget-friendly mattress and prefer a more enveloping feel than the Purple Mattress's Gel-Flex grid provides, you might prefer the SweetNight CoolNest Pro. This Medium-Plush mattress's cooling performance isn't as strong as the previous pick's, but it's still excellent, especially for an inexpensive mattress. It feels impressively cool when you first get into bed and does an even better job of cooling overnight, making it a good option for hot sleepers. The sleeping surface lets you sink in and contours around you, giving it an enveloping feel and helping it offer enough pressure relief for most side sleepers.
It's responsive and fairly bouncy, so unlike slower-moving mattresses like the Casper Snow, it doesn't feel overly hugging and won't make you feel stuck in place. Otherwise, it offers excellent motion isolation, so if you sleep with a partner, you won't feel most movements. You may feel larger movements, like someone getting into bed, but they dissipate quickly and are mostly felt near the source, making motion less likely to wake you. However, weak edge support makes the sleeping surface feel a little smaller, and it's not ideal if you want a solid surface for getting in and out of bed. It mostly includes lower-quality foam, so it's not particularly durable. Also, while it's a comfortable option for side sleepers, combination sleepers may find it doesn't offer enough support for back or stomach sleeping.

Best Cheap Cooling Mattress
Side Sleeping7.4Back Sleeping7.1Stomach Sleeping7.1Cooling9.0Longevity5.8Energy Transferred Over 1st Hour:63 kJEnergy Transferred Over 8 Hours:215 kJSee all our test resultsFirmness Level:Medium (43 Pa/mm)Pick if: You're an average-weight side sleeper or a lighter back/stomach sleeper and want to spend as little as possible on a cooling mattress.
Skip if: You want a mattress with very strong cooling when you first get into bed.If you're a hot sleeper looking for an inexpensive cooling mattress, check out the IKEA VALEVÅG. This cheap hybrid mattress doesn't feel as cool as the SweetNight CoolNest Pro, so it's not as ideal if you often feel overheated as you're falling asleep. However, it offers fantastic cooling over eight hours, so it won't get warmer and warmer as you sleep. This Medium mattress doesn't provide quite as much pressure relief as the previous pick, but it's a comfortable option for average-weight side sleepers as well as lighter back and stomach sleepers. However, heavier individuals will fully compress its thin comfort layers and feel uncomfortable pressure from the firm springs, so it's not ideal for people in that weight category.
The mattress's polyfoam comfort layers and pocket coil support layer give it a bouncy, responsive feel, so it feels easy to move around on. Its good motion isolation makes it suitable for couples, although unlike the SweetNight, you'll feel your partner's smaller movements as well as larger ones, and it's not ideal for people who sleep lightly. The edge support us just okay, which makes the sleeping surface feel a little smaller. Also, as you might expect for the price, it only includes lower-quality foam, so it's not a particularly durable option.

Best Latex Mattress For Cooling
Side Sleeping7.7Back Sleeping8.0Stomach Sleeping8.1Cooling9.0Longevity8.1Energy Transferred Over 1st Hour:68 kJEnergy Transferred Over 8 Hours:204 kJSee all our test resultsFirmness Level:Firm (67 Pa/mm)Pick if: You want a durable latex mattress with fantastic cooling.
Skip if: You prefer hugging, pillowy mattresses over springy, responsive ones.If you want a mattress made of natural materials or like the springy, responsive feel of latex, you might prefer the Avocado Green. This latex hybrid doesn't have extra cooling features like the Casper Snow's aluminum-graphite bands, but it's made of natural materials, like latex and wool, that help it dissipate heat efficiently. It offers a fantastic cooling performance for hot sleepers, since it has a refreshing feel when you first get into bed and all night, so you won't feel like the mattress gradually gets warmer as you sleep. The good-quality latex comfort layer will help it resist forming impressions and indentations and maintain its performance for longer.
We tested the firm variant of this mattress, which has impressive support for most people but also allows you to sink in, so it offers good performance for most side and combination sleepers. However, you also have the option of adding a 'Comfort Topper' or 'Luxury Topper', which should help make it more conforming for lighter people, but may also affect its cooling performance. It's also available in 'Medium' or 'Plush' firmness levels.
Notable Mentions
-
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.

Casper Snow Max:
The Casper Snow Max is a high-end mattress that you might prefer to the Purple RestorePlus Hybrid if you're a lighter or average-weight side sleeper. It offers a more enveloping feel and better pressure relief, along with fantastic cooling, although the Purple still dissipates heat much more efficiently.

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 their 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.
What’s the difference between feeling cool at bedtime and staying cool all night?
There are two parts to our cooling test: energy transfer during the first hour you're in bed, and total energy transfer over eight hours. If you want a mattress with a refreshing feel as soon as you get into bed, you can look for a score of at least 8.0 for Energy Transferred Over 1st Hour. Meanwhile, mattresses with a high energy transfer over eight hours maintain a cool feel all night, so that result is particularly important for hot sleepers who usually feel hot later on. If feeling overheated often disturbs your sleep, you'll want a mattress with a score of at least 8.0 for Energy Transferred Over 8 Hours. The most cooling mattresses, like the Purple RestorePlus Hybrid, offer fantastic cooling when you get into bed as well as all night.
All Reviews
The recommendations above are what we believe are the best mattresses for hot sleepers, based on overall performance and, of course, cooling capabilities. We also factor in the price, feedback from our visitors, and availability.
However, choosing a mattress is a personal decision, and many factors, including sleeping position, body type, and preferences, will come into play. If none of these picks are the perfect fit for you, here's a list of all our mattress reviews, sorted by cooling performance, so you can find one that's just right.
