Cooling Mattresses: What Experts and Editors Say About Four Picks

For people whose sleep is often interrupted by feeling too warm, a mattress’s materials and construction may be worth a closer look. The four options selected by Prevention editors and sleep experts vary in feel and material, but each is presented as offering features intended to limit heat buildup. Their descriptions come from expert guidance and editor reviews, not a direct comparison trial of all four mattresses.

Why mattress temperature can matter

Sleep onset is associated with a drop in core body temperature, sleep expert Raj Dasgupta, M.D., has previously explained to Prevention. If you’re uncomfortably warm, settling into sleep may be harder. The source cites a commonly suggested bedroom range of 60 to 67°F, while recognizing that some people can’t set their room to that temperature. A mattress designed to encourage airflow may be one factor to consider alongside the broader sleep environment.

Chelsie Rohrscheib, M.D., a sleep expert and neuroscientist, describes cooling mattresses as products designed to move heat away from the body and reduce heat buildup. Breathable materials can help air circulate and may retain less body heat than some traditional mattress materials. “Cooling” is not a guarantee that a mattress will keep every sleeper comfortable, though: warmth can depend on the person, the bedding and the room, as well as the mattress.

Prevention drew its selections from existing mattress guides covering side, back and stomach sleepers, along with editor reviews of the Leesa Sapira Chill Hybrid, Avocado Organic Green and Saatva Latex Hybrid. The recommendations also reflect input from Dasgupta, Rohrscheib and family medicine physician Scott Nass, M.D. The article does not report a head-to-head test with standardized temperature measurements, so readers should treat the picks as product suggestions informed by reviews and expert comments.

Four options with different materials and feels

Leesa Sapira Chill Hybrid. The editor writing about this mattress and Assistant Editor Jenn Gonick describe it as comfortable and supportive, with a cool-to-the-touch cover. Its GreenFlex Foam sits above zoned springs, a construction the editors say allows airflow through the mattress. The reviewer reports sleeping on it for more than two years without waking drenched in sweat. That is a personal account, rather than evidence that the mattress will prevent night sweats for other people. Prevention has also selected it for guides to mattresses for side, back and stomach sleepers. Those labels reflect editorial recommendations; individual fit can still vary.

Nectar Premier memory foam. Rohrscheib recommends this model as a comparatively affordable choice, describing the brand as offering quality while keeping prices accessible. The Premier pairs a soft, supportive feel with a cool-to-the-touch cover; the source says it is up to 60% cooler than Nectar’s classic version. That comparison is attributed to the product description, and the article gives no test method or independent temperature results. Rohrscheib cautions that memory foam may feel too soft for people seeking firmer support. Its motion control may suit people sharing a bed with a partner who moves during the night, though comfort remains a personal preference.

Avocado Organic Green Mattress. This option uses cotton, organic wool and latex, along with coils. The materials and coil construction are described as promoting airflow, while the wool is said to wick moisture. In her review, Associate Commerce Editor Hannah Jeon says she did not overheat during testing, even with a heater on, a comforter and a heavy weighted blanket. That experience suggests the mattress worked well for her under those conditions; it does not establish how it will feel for every sleeper. The article presents it as a plastic-free alternative for shoppers interested in natural materials.

Saatva Latex Hybrid. Made with natural latex and vented airflow channels, this mattress is described as buoyant and breathable, with a firmer feel. Contributing writer Tina Martinez calls it a strong fit for people looking for firm support, particularly back sleepers. She also warns that, although the company calls it medium-firm, it felt much firmer to her and may not suit people with back or hip pain. That distinction matters: support and temperature are separate considerations, and a mattress that feels cool may still not match someone’s comfort needs.

What to weigh when comparing mattresses

Material labels alone don’t tell the whole story. Rohrscheib advises looking for breathable materials or cooling features such as gels, and says synthetic materials can retain heat and limit airflow. Nass argues that breathability may be more useful to assess than a “cooling” label: innerspring and hybrid designs can allow more airflow than dense foam, while open-cell foam and perforations may help reduce trapped heat compared with conventional memory foam.

Support is another part of the decision. Dasgupta says sleep position affects where the body bears weight and how the spine curves during sleep. He recommends softer mattresses for side sleepers, medium ones for back sleepers and firm ones for stomach sleepers to support alignment. Those are broad suggestions, not a personal assessment; preferences and comfort differ, and the source doesn’t claim that a particular feel will address pain.

A mattress topper is another product category the source suggests considering, but it doesn’t establish how much a topper would change temperature or comfort with any of these mattresses. The practical takeaway is to compare the materials, airflow, firmness and your usual sleep position together. If overheating is persistent or occurs alongside a health condition or treatment, a doctor or pharmacist can help discuss possible factors and suitable next steps.
