The 10 Best Cooling Mattresses for Hot Sleepers (2026)
It happens to the best of us: You wake up in the middle of the night, clammy and soaked in sweat. If you’re a hot sleeper, a cooling mattress may be for you. Waking up sweaty and hot can be caused by several factors, like sleeping conditions, stress, excessive blankets, the wrong pajamas, and even eating spicy foods before bed. Hot nights can also equate to sleepless nights. According to a study from the Journal of Physiological Anthropology, heat exposure increases wakefulness and decreases time spent in deep sleep and REM sleep.
A cooling mattress is built specifically to help regulate your body temperature by being made of materials that optimize airflow and draw heat away from your body as you sleep. I (and some of my sweatiest colleagues) tested a myriad of cooling mattresses for at least a week each in our homes—to determine which worked best to beat the heat.

Updated August 2026: We've overhauled this guide with new picks from Bedgear, Helix, Brooklyn Bedding, Birch, Sijo, and Nectar. We've also updated links and prices.
This is a crowd-pleaser—a medium-firm hybrid mattress that uses six layers to offer all the benefits of both foam and coils. Below the plush cushion top, there are layers of cooling gel foam to regulate body temperature and disperse heat, and then below are several denser foams for support. Individually wrapped coils on the bottom are zoned so that you have firmer coils in areas like your lower spine that need more support to prevent back pain.
The Midnight Luxe comes with a Tencel cover—a semi-synthetic fiber made from eucalyptus—that helps to circulate airflow and regulate temperature. Plus, there's an optional GlacioTex Cooling Cover ($199) or a combination of the GlacioTex Cooling Cover and CoolForce Layer ($399) that uses enhanced cooling technology. Made from Helix's heat-conductive fabric, it draws heat away from the surface of the mattress. The CoolForce Layer is directly on top of the mattress, designed to pull heat away from the body. The company claims it keeps you 4 degrees cooler for over 12 hours while sleeping.
Helix Midnight Luxe ranges from $1,436 for a twin mattress to $2,924 for a California King.
I haven’t been the biggest fan of hybrid mattresses in the past. I’m a lifelong fussy sleeper and insomniac, and my body prefers soft and sinking, not firm and bouncy—the last hybrid I tested left me feeling like I was sleeping in the backseat of a ’79 Buick. However, the older I get, the more I’m accepting that sinking memory foam is not my friend. It makes it harder to move around at night, and as a stomach sleeper, it provides zero support for my spine. I tested the Aurora Luxe in Soft with the optional pillow top, and it’s the first hybrid I’ve ever tried that I actually like. The pillow top provides the memory-foam feel my body craves while the 8-inch zoned coils give solid support.
Despite arriving tightly compressed in a box, the Aurora Luxe eventually puffed up to an impressive 14.5 inches, and the silky navy blue cover lends a high end aesthetic. Hybrids run cooler in general due to the open-spring design, and the Aurora Luxe’s pillow top contains ThermoPhase “cooling foam.” Though, to be frank, this did not feel overtly cooling to either my husband or me during our three-week test. (The deep dimples on the top, however, do create some extra airflow.) Luckily, Brooklyn Bedding offers a 120-night trial, so you can decide for yourself (returns do cost $99). The Aurora Luxe tends to run firm, so though it comes in Soft, Medium, and Firm, the Soft is more of a medium-firm. I’d only recommend Medium or Firm if you’re looking for firm-firm. —Kat Merck
