The Best Cooling Comforters, Tested by Bedding Experts

A game-changer for sweaty sleepers, this cooling comforter from REST actually feels cold to the touch. Its silky smooth performance fabric aced our moisture-wicking evaluations in our Lab, easily wicking away a sweat-like solution. We appreciated its thin, lightweight feel to prevent overheating to help keep you cool and dry. Note that this comforter is very thin compared to an all-season comforter.

The REST comforter received perfect scores from testers for maintaining a comfortable body temperature, and one tester shared that it "feels soft and cool (almost icy even), providing much-needed relief in hot weather and wicking away any night sweats for a restful sleep." It's especially great for anyone experiencing menopause or pregnancy hot flashes. One tester reported, "I am pregnant and having a cooling comforter was amazing." Another said, "I no longer wake up drenched in sweat!”

This affordable lightweight comforter from Linenspa is an undeniable deal. Its down alternative fill boasts a 300 gsm weight, meaning it's super lightweight compared to traditional comforters which tend to be much thicker. The box stitch design helps keep the fill in place, but it doesn't keep the fill as secure as baffle box construction which can be seen on many of our other featured comforters.

It's available in six colors, and you can use this comforter with a duvet cover or without — there are eight built-in corner ties to keep it secure inside your duvet cover. Keep in mind that this comforter doesn't feature specific cooling or moisture-wicking technologies but is very lightweight for a more comfortable feel in the summer. With a whopping 128,000 reviews on Amazon, this comforter is wildly popular.

Featuring Outlast technology, which stores and releases your body heat to help keep you at a comfy temperature all night long, this comforter from Slumber Cloud provides the ultimate cooling effect. It's lightweight with a 300 gsm down alternative fill, and the cover is a nylon and spandex jersey with a silky feel for an extra cooling effect — though some testers said it felt too slippery.

While some cooling comforters are super thin, this comforter still feels substantial. "I love how plush it is with a cooling effect," said one tester. "Most cooling comforters tend to be flatter but I found this one had some cushion to it." Another tester who suffers from hot flashes reported, "It really did help keep me from getting overheated at night." One tester shared that it became her new favorite comforter and said, "I was worried it'd feel paper thin and that I'd need to layer more blankets on top to feel comfy, but it offers a great thickness that feels both lightweight and cozy." Multiple testers also loved how easy this comforter was to launder, saying it dried quicker than their other comforters.

Buffy — famous for its original Cloud Comforter — released a cooling Breeze Comforter just for hot sleepers. This down alternative comforter is lightweight and breathable, and testers loved the silky soft feel of the Tencel lyocell cover that also helps keep you cooler; it has an immediate cooling effect and it wicks away moisture to keep you dry, even if you suffer from night sweats.

The silky feel did mean it was prone to sliding around on testers' beds or inside a duvet cover. One tester shared, "The comforter is lightweight and fluffy. It’s perfect for summer nights or hot sleepers," and they said it feels "very soft and comfortable, with and without a duvet cover." Loving its cooling effects, one tester said this comforter was "significantly cooler than my down duvet." Another adds, "The comforter feels very quality, luxe and hotel-like."

While some comforters can be paired with a duvet cover or used as-is, this pick from Birch is specifically designed as a duvet insert. It's made with a mix of down and wool for a fluffy feel that's great year-round. We especially appreciate its baffle box construction and convenient corner loops that keep it in place in a duvet cover.

One tester loved its cooling effects, saying, "I am a hot sleeper but the comforter never felt too hot and my husband is a cool sleeper and was comfortable all night." Another tester reported, "It looks great on my bed, it's cool-feeling but also keeps you comfortable." Praising the cover material, one tester called it "soft and smooth to the touch." Note that this pick isn't available in Twin sizing.

Get the fluffy feel of real down without overheating with this pick from the brand famous for its mattress in a box. Casper's duvet is a down comforter designed for the summer months. It has a layer of merino wool to help wick away moisture as you sleep to help prevent you from getting too hot. It comes in two thicknesses, and the lightweight option is especially great for hot sleepers. While we haven't tested this specific style in the Lab yet, we are constantly impressed with Casper products for their quality and innovation.

If you want a fluffy comforter but have a down sensitivity, opt for a down alternative pick instead. This top-tested style from Crane and Canopy is available in three weights: all-season, lightweight and super lightweight, which is ideal for hot sleepers. It is constructed with baffle boxes, which help keep the fill evenly distributed and prevent clumping. With edge piping, it's chic enough to use without a duvet cover, but it also has corner loops to keep a cover secure.

Testers loved that the fill stayed evenly distributed, noting that it didn't shift, clump or poke through the smooth cotton cover. Calling it "luxurious" and "fancy," one tester said, "It's light enough that it doesn’t make you sweat but yet you feel snug under it." Some testers experienced a bit of a crinkling noise when using it without a duvet cover.

Many are surprised to learn that wool is actually great for sweaty sleepers. It has natural temperature-regulating properties to help keep you at a more comfortable body temperature. This Woolroom comforter was a game-changer for many of our hot sleeper testers. One tester shared, "I am a very hot sleeper — I usually wake up in the middle of the night sweating but this is the first comforter in so long that I haven't sweat in my sleep with." She even added, "It is a miracle because I have tried so many." It's on the thinner side, so it's not ideal if you want a super fluffy feel.

This comforter uses organic materials and is GOTS-certified, meaning the entire process of producing the wool fill and cotton cover follows strict organic guidelines. The outer cotton cover is undyed, which is why it's only available in one shade. Woolroom's collection also includes a wool pillow and a mattress pad, which were popular among testers too.

For ultimate cooling, this comforter from Pottery Barn uses 37.5 technology — designed to prevent overheating while you sleep — in the fill and the outer fabric. Made with a mix of polyester and 37.5 performance polyester, this comforter is designed for ultimate temperature regulation. 37.5 technology absorbs heat to help to prevent night sweats from occurring. The convenient corner loops make it easy to use a duvet cover too. This pick uses box stitching (not baffle box construction) so fill may shift a bit during use. Although we haven't tested this exact style yet, we have tested many bedding products from Pottery Barn and continue to be impressed by the brand's excellent home offerings.
