The Best Cooling Mattresses for Hot Sleepers

It's hard to find a mattress as breathable as one from Purple. Unlike memory foam which doesn't have much ventilation, this pick uses a unique, grid-shaped elastic top layer that is airy yet still supportive. Purple's GelFlex Grid has a one-of-a-kind texture with a squishy quality that feels both responsive and pressure-relieving, making it great for anyone who wants to try something new.

How it cools: While it doesn't have extra cooling technology, the breathable construction helps prevent overheating caused by lying directly on foam. The squishy grid also lies directly under your body for optimal ventilation.

Tester notes: Our testers and panelists highlighted how it felt noticeably cooler than other beds they've slept on. A few even called it "too cool" in the winter. The unique texture won over many, including one user who told us, "It's 'springy' and conforms to my body while still being supportive."

Some testers also appreciated how the bouncy layer had good motion isolation, and others said it feels like a perfect balance of soft and firm. Still, several reviewers found that the delivery took longer than they expected.

This foam mattress is a total steal and has built-in features to help prevent overheating at night. It's ideal for those who like the contouring feel of a memory foam bed without getting too hot or stuffy at night. While it may feel as cool as pricier models, it offers a good level of cooling for the price.

The boxed configuration is also convenient, meaning you can order it online and set it up once you're ready, without needing to schedule a delivery.

How it cools: The breathable open-cell foam is embedded with graphite and gel to help draw away heat from your body.

Tester notes: The majority of our panel told us they were able to maintain a comfortable body temperature while sleeping on their Tuft & Needle mattresses. One hot sleeper shared, "I have insomnia, and I have slept better on this mattress than any other mattress." Others also highlighted the easy setup and how their partners couldn't feel them move around in bed. The main call-out is that there isn't as much edge support, meaning it may sag when you sit on the side of the mattress.

Not only does this cooling mattress have more than 35,000 five-star reviews on Amazon, but it's also a fraction of the cost of other mattresses on our list. Plus, it arrives at your house within days of ordering and there are several heights to choose from (ranging between 6 inches to 12 inches).

How it cools: There's a layer of gel-infused memory foam at the top, which helps draw heat away from your body and its open-cell structure makes it more breathable.

Tester notes: Users found it to be comfortable to sleep on and said it didn't cause any overheating. One even reported experiencing less back pain and another called the bed "easy to order, not expensive, easy to set up [and] just as comfortable and good-quality as expensive mattresses."

Our most recent tester for this model also gave it a perfect score when we asked if they stayed at a comfortable temperature throughout the night. Though it didn't fully take shape after opening in our review, and it doesn't feel as luxurious as pricier models, it's still a great option if you're hoping to spend less and shop on Amazon.

Casper's Snow Mattress adds advanced cooling technology to a classic foam hybrid. It's got the cushiony, pressure-relieving feel you'd expect, with a versatile medium firmness. Plus, if you're a side sleeper, this pick isn't too firm to help keep your spine aligned.

How it cools: Featuring a cool-to-the-touch cover, Phase Change Material (PCM), cooling gel and HeatDelete bands over pocketed coils, it's designed to pull away excess heat from your body, but still has the textbook cradling feel of memory foam.

Tester notes: Casper recently re-launched its entire mattress line-up, and our consumer testers for this updated model have been happy so far. "It's soft enough, yet provides great support and conforms to my rapidly aging body," noted one tester. "Even after a workout, walk or yard work, I don't feel as stiff and sore getting out of bed as I have in the past." Others called Casper's cooling features "extremely noticeable" and noted huge differences in their sleep quality.

Though it has a medium firmness rating, some said they were surprised that it was softer than expected — which may actually be a benefit for side sleepers.

While most cooling mattresses simply feel cool to the touch, this innovative mattress uses unique Phase Change Technology that's been tested to keep you feeling up to 10 degrees cooler than usual all night. It's expensive, but if you're willing to invest in a top-quality mattress with proven cooling capabilities, the LuxeBreeze is one of the best. Plus, it's made with Tempur-Pedic's famous high-quality foam.

The brand also offers the ProBreeze mattress, which keeps you up to 5 degrees cooler instead of 10 at a lower price.

How it cools: Under its cool-to-the-touch cover, various layers are designed to absorb, diffuse and disperse heat, thanks to its Phase Change Technology. The popular medium hybrid option also adds coils for more breathability.

Tester notes: The brand recently re-engineered this mattress, upgrading from an 8-degree cooler sleep to a 10-degree cooler sleep, and it's proven more than exceptional in our tests. Testers praised the noticeably cold feel and how they don't feel their partners moving as they do on other foam mattresses. Our most recent tester shared, "I’m not overheating throughout the night as often (if ever!), which used to happen pretty frequently [on my old mattress]."

Most soft mattresses use memory foam, which is known to retain heat, but this one is designed to pull heat away from your body. It has a cool-to-the-touch cover (that our testers loved) along with excellent pressure relief and cushiony comfort. The Euro-top provides a nice touch that lives up to the 'Luxe' name.

How it cools: Under the cool-to-the-touch cover, the mattress uses layers of foam infused with Phase Change Material (PCM) over breathable coils for added air flow.

Tester notes: Many hybrid beds claim to sleep cool, but this one proved noticeably cooler over time compared to similar models, according to our testers and panelists. "The cooling technology is far better than our old mattress," said one user.

Others also commented on the plush feel. One Textiles Lab analyst described her medium version as having "a cloud-like feel that relieves pressure around my shoulders and hips, so I’m not just lying on top of the mattress." Note that this model ran a bit soft in our evaluations and the pillow-top will cost extra.

If you prefer the feel of a traditional mattress instead of a bed-in-a-box, Saatva gives you the quality of in-store models with the convenience of online shopping. The Classic Mattress is one of the best we've tested, featuring excellent support, especially around the edges. The brand also offers free white glove delivery and removal along with a 365-day sleep trial — just remember, you'll have to pay a $99 pick-up fee if you decide to return it.

How it cools: It doesn't have any added cooling features like the other mattresses in our round-up, but it's made with coils that are inherently more breathable than all-foam styles.

Tester notes: Our consumer panel has consistently given Saatva top ratings for comfort, support and overall sleep quality. Most, including several GH staffers, found that they sleep at a comfortable temperature throughout the night.

In addition, they loved its superior edge support, which has impressed our experts, and said it makes it easier to get in and out of bed. Beyond that, the brand stands out for its top-notch customer service, surprising some users with near-instant attention compared to the all-too-common long wait times many expect.

For hot sleepers, cooling technology and inherent breathability are musts when it comes to shopping for a mattress, especially one made with foam. Serta's Arctic Collection is engineered to pull away excess heat from your body without compromising on comfort and comes in hybrid and all-foam variations. The contouring memory foam also cradles pressure points.

How it cools: The brand's Reactex technology uses phase change material and gel within the top foam layers to pull away your body heat and transfer it deep within the mattress. The hybrid version also comes with breathable coils.

Tester notes: While this one comes with limited feedback compared to some of our other picks, those who own it swear by it. One tester even commented, "I haven’t woken up with night sweats since sleeping on it."

It's also earned especially high scores for comfort, temperature regulation and support, with reviewers stating they experienced a noticeable improvement in their sleep quality. Just note that while the brand offers free shipping, the mattress comes already expanded, and setup is extra.

For those who suffer from pain in their shoulders, hips or lower back, maintaining neutral spinal alignment while sleeping is very beneficial. Nolah's mattresses offer everything you'll need to do just that, from pressure relief and support to a medium level of firmness. This specific model earned dozens of positive reviews from our testers and panelists, who swore it made all the difference for their back and hip pain.

How it cools: The brand's AirFoam differs from memory foam because it uses open-cell structures to maximize ventilation. This means that the foam is inherently more breathable than memory foam with perforations.

Tester notes: Multiple users who've suffered from joint pain told us this bed notably eased their discomfort. One owner praised the model for its comfort, and shared that it "offers back support while still cradling pressure points."

Plus, while foam is known for trapping heat, our reviewers told us this one sleeps surprisingly cool compared to others they've owned. Note that the 10-inch height may be too low for those with mobility issues, depending on the height of your bed frame.

Sleep Number beds are famous for their air-filled chambers that let you pick your perfect firmness level so you can get comfortable whether you're a side, stomach or back sleeper. This is especially helpful if you aren't sure what level of firmness is right for you, as you can change it as you please to find 'your number,' or if you have a different preference than your partner.

How it cools: This model features foam that's infused with ceramic, which draws heat away from your body, on top of adjustable air chambers.

Tester notes: Users were impressed with their sleep quality as well as being able to control their firmness level. And though Sleep Number beds are pricey, reviewers on our panel said they were worth the cost. One of our experts even said, "I was really impressed with how it learned and reacted to my body. It didn't feel gimmicky, seemed really intelligent and actually worked."

Keep in mind that all Sleep Number mattresses need to be paired with a matching base, ranging from simple bed frames to adjustable bases.
