We designed the ThermaCool topper with groundbreaking heat-dissipating bands, placed exactly where your body generates the most heat. Experience up to 6.94 °F of cooling, all night long.

Most "cooling" products feel cold, then go back to being hot seconds later. We changed the sleep game with three layers of cooling foam, plus a passive heat removal system (our patented ThermaCool Bands) that remove heat... All. Night. Long.

Feel cool instantly, stay asleep easily.

We designed our mattress topper according to the best research.

Leading sleep research shows that medium-firm mattresses are best for reducing back pain during sleep, with studies citing a 48% reduction in back pain and a 55% improvement in sleep quality.

We've calibrated our mattress topper at the perfect medium firm (8/10), to ensure you have the perfect balance of comfort and support and never wake up with back pain again.

Unlike some $1,000+ cooling toppers that require power and cycle cold water through your bed, ThermaCool uses passive, science-backed cooling materials to regulate temperature naturally - no plugs, pumps, or noise needed.

We're so confident in our mattress topper we offer a 60-night guarantee. If the ThermaCool Mattress Topper doesn't help you manage heat, you can feel confident with our hassle-free returns and shipping program.
