9 Best Cooling Mattresses for Hot Sleepers

If you overheat at night, chances are your sleep quality isn't great. In fact, it's nearly impossible to have a restful sleep if you're dealing with night sweats. The good news is that whether you suffer from hot flashes or are sweating in warm temperatures, cooling mattresses – along with other cooling bedding like sheets, pillows and blankets – can help you comfortably catch some ZZZs.

The Good Housekeeping Institute's Textiles Lab reviews mattresses of all kinds — from foam boxed mattresses to organic mattresses to hybrid mattresses and more — by evaluating aspects like the materials, features and brand's policies in our Lab, then sending the mattresses to product experts and testers to try out in real life. We also survey our consumer tester panel to get in-depth feedback on the beds they already own. Based on our latest survey, we thoroughly reviewed responses from over 10,000 mattress owners before making our recommendations.

You can learn more about how we evaluate mattresses and find expert shopping tips at the bottom of this article. We most recently updated this article in April 2022 to provide more testing specifications and shopping tips, and continue to stand behind these recommendations. Based on our team of fiber scientist's evaluations and panel feedback, here are the best cooling mattresses to sleep on:

Tempur-Pedic

This innovative mattress uses unique phase change technology that's been tested to keep you feeling up to eight degrees cooler all night instead of just feeling cool to the touch. It's expensive, but on top of the impressive cooling features, this mattress has the high-quality foam that Tempur-Pedic is famous for. For a slightly lower-priced version, the brand also has the ProBreeze mattress that gets up to three degrees cooler instead of eight.

What it's made of: A machine washable outer cover, a layer of phase-change material that absorbs heat to help you feel cool, comfort foam with additional phase-change material and pressure-relieving foam with ventilation for breathability.

Tester notes: Testers told us it feels noticeably cooler and they don't feel their partners moving like they do on other foam mattresses. One told us it still feels new after years of using it, while another raved, "We have slept so well since getting it."

Though it doesn't have as much of a cooling effect as the Tempur-Pedic pick, this foam mattress is a total steal and has features to prevent overheating that can cause night sweats. It has charcoal and gel embedded to help draw heat away from your body and the foam has open cells that make it more breathable. It's a mattress-in-a-box so you can order online and set it up at your convenience without scheduling a delivery.

What it's made of: A soft and stretchy outer cover with two layers of foam. The top has softer cushioning foam for pressure relief and comfort, while the bottom has firmer foam for support.

Tester notes: The majority of our panel told us that they're able maintain a comfortable body temperature while sleeping on their Tuft & Needle mattresses. They also gave it high scores in other areas, like ease of ordering, set up, comfort and support. The main callout is that there isn't as much edge support, meaning it may sag when you sit on the side of the mattress.

This model from Casper is an ideal mattress for side sleepers because it keeps your spine aligned.

For an added cost, you can opt for the Wave Hybrid mattress, which has coils for even better support and more breathability.

What it's made of: From a cooling perspective, it has several layers of foam that vary in density, including its signature AirScape foam that has holes for breathability and a built-in layer of cooling gel.

Tester notes: Testers enjoyed the pressure relief and cradling comfort when lying on this mattress. Though it's a medium firm rating, some said they were surprised that it was softer than expected — which may actually be a benefit for side sleepers.

This foam mattress comes with cooling cover that works through an app on your smart phone. You set your preferred temperature setting for each side of the bed (it can heat up, too!) and water runs from a hub – i.e. a unit next to your bed – to create the cooling effect. You can schedule when to turn the temperature settings on and off, plus the cover has built-in sleep tracking capabilities.

What it's made of: Inside there are five layers of foam ranging from comfort foam on top to support foam on the bottom.

Tester notes: Our pros were impressed by the high-tech features that make it stand out from other cooling mattresses. The downside was the mattress itself felt fairly soft and didn't have good edge support, but you can purchase just the cover if you want to use it over a different 10- or 11-inch mattress.

• Firmness level: Medium
• Sizes: Full, Queen, King, California King

Tester notes: Reviewers have told us they love sleeping on the mattress and find it to be comfortable. They especially liked how well it conforms to their bodies. Though many didn't notice any strong cooling effects, most users told us they maintained a comfortable body temperature.
