Best Cooling Mattress of 2024

Our CNET Sleep editors have hundreds of mattress testing hours on their resumes; they know the beds that shine and the beds that are underwhelming. With so many to test and so few spots on our list, we aren’t able to showcase every quality cooling mattress. We do want to give a few more beds the honorable mention they deserve. 

Purple mattress: The original Purple mattress uses a Hyper-Elastic Gel Polymer grid that has a ton of air pockets. It’s one of the best materials for not retaining heat. We rate it around a medium or five out of 10 on the firmness scale. 

Loom & Leaf mattress: With two firmness levels that sit toward the firm end of the spectrum (medium-firm and firm) and a special cooling gel layer, Loom & Leaf is a great mattress to help with temperature regulation. You sit more on top of the mattress rather than inside, and the cooling gel is actually effective. 

WinkBeds EcoCloud mattress: WinkBeds doesn’t actively cool you, but it’s made with a breathable, non-heat-retaining latex foam material and pocketed coils. This allows for increased airflow, breathability and comfort. Not to mention, latex beds are hypoallergenic and antimicrobial.

Nectar Premier/Premier Copper mattress: These are Nectar’s premium mattresses, made with cooling gel foam inside and a cooling cover that helps wick away moisture. The Copper model takes it a step further with added copper fibers that help absorb heat from your body and disperse it throughout the bed. They’re rated around a six to seven on the firmness scale, so you don’t sink into the foam as much. 

Saatva mattress: Saatva is a pillow-top mattress that contains breathable materials and offers firm profiles that help you rest more comfortably at night if you’re a hot sleeper. It’s a luxury mattress available in two different heights and three different firmness levels. That means it can accommodate all body types and most sleeping positions unless you’re a strict side sleeper who wants a plush and fluffy mattress.
