The 10 Best Cooling Mattresses for Hot Sleepers (2026)
Nothing ruins a great night of sleep faster than getting too hot. We slept on a myriad of cooling mattresses to find which ones drew the heat away best.
The 10 Best Cooling Mattresses for Hot Sleepers (2026)
Waking up sweaty and hot can be caused by various factors, including sleeping conditions, stress, excessive blankets, unsuitable pajamas, and even consuming spicy foods before bedtime. Hot nights can lead to sleepless nights. A study from the Journal of Physiological Anthropology reveals that heat exposure increases wakefulness and reduces deep sleep and REM sleep time.
To combat this issue, cooling mattresses are designed to regulate body temperature by utilizing materials that optimize airflow and remove heat from the body during sleep.
A team of testers, including the reporter and colleagues, evaluated numerous cooling mattresses for at least a week in their homes to identify which ones best alleviate heat. In addition to this comprehensive review, readers are encouraged to explore other sleep-related guides, such as the Best Mattresses, Best Organic Mattresses, Best Hybrid Mattresses, and Best Bed Sheets.
The updated guide for 2026 has been thoroughly revised, featuring new mattress recommendations from Bedgear, Helix, Brooklyn Bedding, Birch, Sijo, and Nectar. The links and prices have also been updated accordingly. This guide is particularly popular, offering a medium-firm hybrid mattress that combines the advantages of foam and coils.
The mattress consists of six layers, with the plush cushion top followed by cooling gel foam layers to regulate body temperature and dissipate heat. Several denser foams provide support underneath.
The mattress features individually wrapped coils at the bottom, strategically zoned to offer firmer support in areas requiring extra assistance, such as the lower spine, to prevent back pain. The mattress comes with a Tencel cover—a semi-synthetic fiber derived from eucalyptus—that promotes airflow and temperature regulation. Additionally, there are two optional cooling covers available: the GlacioTex Cooling Cover ($199) and a combination of the GlacioTex Cooling Cover and CoolForce Layer ($399).
The CoolForce Layer, made from Helix's heat-conductive fabric, draws heat away from the mattress surface, allegedly keeping the user 4 degrees cooler for over 12 hours while sleeping.
