REST® Evercool® Cooling Comforter Blanket for Hot Sleepers, King/Cali King

The REST Evercool Cooling Comforter is the premium option for hot sleepers. The king/Cal king size costs about $249 and has 4.3 stars from about 4,100 Amazon reviews.

What you're paying for

Two things set it apart from cheaper cooling comforters. The shell is REST's own knitted cooling fabric, which the brand says is lab rated cooler to the touch than silk. And the fill is a blend of Sorona and Tencel rather than plain polyester. Tencel is a lyocell fiber that handles moisture well, which matters if you sweat at night.

REST says it's lightweight and breathable enough to use year-round, and that you don't need a flat sheet with it. It's machine washable and dryer safe, and the brand says the fabric resists snags, pilling and pet hair. REST also lists Good Housekeeping bedding awards from 2023 through 2026.

Who it's for

• Hot sleepers who want one comforter to leave on the bed most of the year
• People dealing with hot flashes, which REST specifically mentions
• Anyone who has tried cheap cooling blankets and wants something more substantial

Who should skip it

Anyone on a budget. You can get most of the summer benefit from a $50 Elegear cooling blanket. And if you sleep in a cold room in winter, test whether it's warm enough before cutting your other bedding.

If night sweats are heavy and new, or come with other symptoms, see a doctor. Bedding can make you more comfortable, but it won't treat the cause.

Alternatives

The Cozy Bliss cooling comforter gives you a cooling shell and some loft for about $76 in full/queen. Our best comforter for hot sleepers guide compares fills and weights, and why you can't sleep when it's hot explains why heat ruins sleep in the first place.

A comforter is only one layer. If your mattress is memory foam, a cooling mattress topper or pad deals with the heat coming from below.
