There’s nothing worse than waking up in the middle of the night drenched in sweat. You went to sleep just fine, but your mattress warms up throughout the night. It’s basically torture. In this post, we’re going to run through our hand-selected list of the coolest mattresses on the market. If you sleep especially hot, this post is for you.
There’s a lot to consider with a mattress beyond its airflow or ability to regulate temperature, so we’ll also cover a few other important elements to consider. If you’re just starting your mattress hunt, however, you should check out our Mattress Finder Quiz, which only has a few questions, but will help to narrow your list. For now, though, let’s talk best mattresses for hot sleepers.
The Brooklyn Bedding Aurora is a coil mattress that incorporates various technologies and textiles to actively cool you down at night. For a lot of people, it’s probably going to be too cool, but if you sleep unimaginably hot at night, it’s one of the best beds available today. It does come in three different firmness levels (Soft, Medium, and Firm) and offers plenty of support for heavier individuals.
For the record, the Brooklyn Bedding Freya is very similar to the Aurora and is made in the same facility—so in reality, you can basically take your pick of the two. We chose the Aurora because it’s more popular.
Purple makes four of the most interesting mattresses on the market today. They started with the Original Purple bed that was great for airflow and was pretty darn comfortable, but that lacked support for larger individuals. In 2018, they rolled out the Purple.2, Purple.3, and Purple.4, which still use Hyper-Elastic Polymer (the company’s patented gel-like top layer), but the new models now have a base of coils rather than poly foam.
The new models are heavy, difficult-to-move beds, but they now offer a heck of a lot more support and still have great airflow. The big reason to get a Purple mattress, though, is that you want a nice combination of airflow, responsiveness, pressure relief, and support—you won’t find that with many mattresses beyond those from Purple.
Cocoon Chill by Sealy is a moderately-priced bed that uses phase-change materials in its cover to keep you cool at night. It won’t sleep as cool as the Brooklyn Bedding Aurora, but it also costs less. And one nice thing about Cocoon is that it comes in two different firmness levels, although they do feel very similar and are best for back, stomach, and combo sleepers.
If you’re open to a dense memory foam feel, Cocoon is a pretty darn good option. Plus, it’s a bed-in-a-box mattress that comes with a 100-night trial period and free returns, which is great if you’re not 100% certain what you want in a mattress.
Nature’s Sleep, the company behind GhostBed Luxe, claims that this is the coolest mattress in the world. It is indeed cool to sleep on, but we don’t think it’s the coolest mattress that money can buy. Regardless, if you’re looking for a thick, comfortable, medium-firm, memory foam mattress that sleeps cool at night, GhostBed Luxe is a great option.
One great thing about GhostBed Luxe, though, is that Nature’s Sleep is constantly discounting it, especially during holidays. So, while it looks relatively expensive on paper, they often have specials that make it more palatable.
Allswell is a relatively new brand in the online mattress shopping space, but it’s backed by one of the world’s largest companies, Walmart. But that’s obviously not the reason that Allswell made this list. We put it on the list because it is a firm, supportive mattress that uses cooling textiles in its cover. The bed is cool to the touch and since it’s firm, you will sleep more on the mattress, rather than down in the mattress.
It also happens to be priced very affordably and comes with free shipping and returns, a 100-night trial period, and a 10-year warranty. Here’s what you should take away from this section: the Allswell Luxe Hybrid is supportive, firm, cool, and affordable. If that’s what you’re looking for, you’re in luck.
For the record, a close alternative to the Allswell Luxe Hybrid is the Big Fig mattress, which narrowly missed making it on the list. Still a great bed—especially for heavy people—but we had to cut it off somewhere.
Some people love and some people hate latex mattresses. They are quite different from typical poly foam beds, but we happen to really like them. Latex, in general, is a very durable material that naturally tends to sleep cool at night.
Latex beds are usually pretty expensive given that they’re more costly to manufacture and ship, but Zenhaven really isn’t—it’s actually fairly affordable for a latex bed. Sure, it’s on the higher end for an online mattress, but it’s not expensive by typical retail standards.
Plus, it’s a pretty luxurious mattress that comes with white glove delivery and a 20-year warranty. It also happens to use certain natural and organic materials, which makes Zenhaven a good pick for health-conscious individuals.
We have tested and reviewed dozens of mattresses, ranging from cheap to luxurious, warm to cold, memory foam to innersprings, and everything in between. And one of the areas that we pay particular attention to is temperature regulation. We have a few hot sleepers on our team and they constantly remind us just how important it is to get a mattress that won’t overheat. This is why in all of our mattress reviews we make a point to discuss temperature regulation—just like firmness level, it can make or break the mattress for you. We spend hundreds of hours testing, researching, and thinking about these beds, which is why we feel so confident that the list above will indeed be helpful. We have numerous methods for testing the cooling properties of a mattress, but in the end, it’s a blend of all of these that helps us to discern whether the bed is worth your time. We pay attention to the types of materials that are used and often will pull out our thermometer gun to test surface temperatures and how quickly a bed returns to room temperature. We admit that this is more art than science, but our findings are based on real experiences from real people. We have individuals on staff that are 225 lb and some that are as light as 95 lb; this gives us a great range of perspectives. If, however, you try out a bed that you think deserves to be on this list, please contact us or, in the event that you disagree with our selections, don’t hesitate to reach out, as well. Either way, we’d love to hear your input.
This is an oversimplification, but hopefully it’s helpful. When you sleep at night, your body heat transfers to the mattress via conduction (i.e. heat transferred through touch). The mattress then retains the heat and continues to warm up even more since your body remains around 33°C or 91°F in normal conditions. You continue to transfer heat and it continues to absorb and retain that heat. It’s an endless cycle that only breaks when you move locations or reduce your surface area by switching from, say, your back to your side. There are certain materials that retain heat more than others. Likewise, there are certain materials that dissipate heat more efficiently than others. In this post, we’ll cover it all.
In general, you should be looking for a mattress that either (1) actively cools you down, (2) allows for plenty of airflow, or (3) both. We have included all three types of mattresses in the list above. A bed that active cools you down will incorporate some sort of special textile or material into the cover or top layers of foam. These beds are best for people that sleep truly hot since they seek to cool your body temperature down. A mattress that allows for great airflow either has aerated foams, coils, or a gel-like material with limited surface area. If you’re bed has both, you’re looking at an icy-cold sleeping experience. These should come with a warning label. Here’s a graphic that shows the relative effectiveness of various types of materials.
Keep in mind that there are always exceptions, but for the most part, you can use the graphic as a guide.
This is more or less an explanation of the graphic provided above. I just want to talk in more detail about mattress construction. We’ll go over covers in the next section because those are very important, as well.
Most people largely ignore the cover of their mattress, but it can be a key element in keeping you cool. If you sleep hot, you should be looking for one of two types of covers.
Phase-Change Material — This helps to pull away your body heat and cool you down. This phase-change material is becoming quite popular. It’s effective at keeping you cool and is actually cool to the touch, even when it’s hot out. It’s impressive stuff. You’ll even see it sometimes incorporated into foams.
Breathability — If the cover doesn’t a have magical textile to keep you cool, then it should at least be breathable. That way you can feel the effects of the gel memory foam or latex foam, for example. If the cover is too thick, it can absorb and retain your body heat, which will intern warm you up even more. As an example, if the cover on Purple mattresses wasn’t breathable, then you’d miss out on a lot of the cooling affects of the Hyper-Elastic Polymer. Testing breathability is fairly simple. Lift a portion of the cover off of the mattress and see how thin or thick it is and also how easy it is to blow air through it.
You want to do your best to completely avoid standard memory foam. As you probably well know, memory foam softens as it is exposed to heat and pressure. That’s why you sink into the bed as you sleep. It’s wonderful for pressure relief and support, but can leave you feeling stuck in the mattress. And then the cycle of heat exchange begins. Getting a standard memory foam mattress is the quickest way to start sweating at night. Now, to be fair, there are certain people that absolutely love memory foam, but that’s not what we’re talking about. We’re specifically talking about temperature regulation. And memory foam is the worst at keeping you cool. Cheaper polyurethane foam isn’t the best either, especially when it’s the top layer on a mattress. You’ll usually see this with cheaper mattresses.
In general, a firmer mattress (usually for back sleepers and stomach sleepers) is going to sleep cooler than a softer mattress, simply because you sleep more on the bed rather than in it. We’ve tried plenty of mattresses that we expected to sleep more in the neutral range, but they ended up being warmer because either the cover wasn’t breathable or the mattress was on the softer end. If you need a more plush mattress, look for one that has a phase-change material in the cover. While the bed won’t be especially cool, it also won’t be alarmingly warm.
This is still memory foam. It will feel like memory foam. It will want to heat up like memory foam. Only this time, it has gel infused to cool you down. There are a few types of gel memory foam, but the goal is the same: to keep you cool, despite the fact you’re sleeping on memory foam. A lot of times you’ll see gel memory foam that has speckles (or microbeads) or a slab of gel. The gel basically makes the mattress cool to the touch and increases room for airflow so that heat can be drawn away from the body.
This is the Holy Grail of mattresses for hot sleepers or people with night sweats/hot flashes. If you get a bed that has phase-change materials plus innersprings or pocketed coils, you’re in for an Arctic experience. It will be cool to the touch and get great airflow from the coils. Do not get these beds if you sleep just kind of warm. They’ll be too cool. Do not get them if your girlfriend or wife is petite and runs cold. She will freeze to death. You should only consider these types of mattresses if you absolutely burn up at night.
Not only can your weight affect how hot or cold you sleep at night, but it can also limit or expand the list of mattress from which you can choose. Allow me to explain. If you’re heavier then you likely sleep hotter at night since you have more mass and surface area, among other things. You also will likely need a mattress with a lot more support since the more weight you have the more stress you’ll be putting on the mattress. As such, you should probably look for an extra thick foam mattress or a hybrid mattress with coils. Here’s our pick for the best mattress for heavy people.
