best cooling comforters

A typical, thick comforter may quickly lead to overheating, especially for hot sleepers. But there's nothing quite like wrapping up in a cozy blanket, no matter the temperature outside. That's why a cooling comforter is ideal for the summer months, but can also be used year-round by hot sleepers looking for relief.

The best cooling comforters for hot sleepers are designed to trap less heat, and many use specialized cooling technology — and you can even continue to use your favorite duvet cover with many of them!

The Good Housekeeping Institute Textiles Lab regularly tests comforters of all kinds, including down comforters, down alternative picks and beyond. In the Lab, GH fiber scientists evaluate each comforter's construction to ensure it is built to last and vet all cooling claims and technologies. We test comforters every year, and this year we tested 28 different styles, putting them through over 220 in-Lab and at-home tests. To find the best buys, we analyze thousands of data points from many years of comforter testing.

Whether you're going through menopause and experiencing hot flashes, or you're just someone who experiences night sweats, these are the comforters that will allow you to sleep more deeply by keeping you cool at night. Keep reading past our top picks to learn more about how we test comforters and expert cooling comforter shopping tips.

Pros
  • Outlast temperature-regulating technology
  • Down alternative
  • Regular or light fill weight
Cons
  • Cotton cover offers less cooling effect than a synthetic cover

This cooling comforter from Slumbercloud uses Outlast technology, which stores and releases your body heat to help keep you at a comfy temperature all night long. Testers especially appreciated its super thin height that's "just the right amount of fluff for hot summer nights," according to one tester. The 100% cotton sateen cover has a soft natural feel but offers less of a cooling benefit than a synthetic fabric would. If you want even more of a cooling effect, we also recommend the brand's UltraCool Comforter which only uses synthetic materials — a favorite among extremely hot sleepers. We love that this brand offers a 60-night trial, so there’s no harm in testing it out!

Pros
  • Budget-friendly
  • Lightweight down alternative
  • Box stitch design to keep fill in place
Cons
  • Not as moisture-wicking as other picks

The affordable lightweight comforter from Linenspa is an undeniable deal. Its down alternative fill boasts a 300 fill power, meaning it's super lightweight compared to most comforters that have over 600 fill power. The box stitch design helps keep the fill in place, and there are eight built-in corner ties to keep it secure inside your duvet cover. Keep in mind this comforter doesn't feature any specific cooling or moisture-wicking technologies but is very lightweight for a more comfortable feel in the summer. With a whopping 122,000 reviews on Amazon, this comforter is wildly popular!

Pros
  • Cool to the touch feel
  • Showed no signs of wear after laundering
  • Aced moisture-wicking testing in our Lab
Cons
  • Some testers found it too thin

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, and we appreciated its very thin, lightweight feel. One tester raved 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." Another said, "I no longer wake up drenched in sweat!” Note that this comforter is very thin compared to an all-season comforter.

Pros
  • Sustainable materials
  • Lightweight and breathable
  • Generous free trial period
Cons
  • Slides around in a duvet cover, according to testers

Buffy — famous for its original Cloud Comforter — released the cooling Breeze Comforter just for hot sleepers. This down alternative comforter is lightweight and breathable, and testers loved the silky soft feel of the lyocell cover that also helps keep you cooler. 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 it feels "very soft and comfortable, with and without a duvet cover."

Pros
  • Organic materials
  • Innovative blend of down and wool
  • Machine washable
Cons
  • Only two size options

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. 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." We especially appreciate its baffle box construction and convenient corner loops that keep it in place in a duvet cover. Note that this pick isn't available in Twin sizing.

Pros
  • 37.5 temperature-regulating technology in fill and fabric
  • Soft and fluffy
  • Convenient corner loops for duvet cover
Cons
  • Box quilting doesn't prevent shifting

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. 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.

Pros
  • Fluffy feel of real down
  • Merino wool layer wicks moisture
  • Lightweight
Cons
  • Pricey

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

Pros
  • Temperature regulating wool material
  • Cotton cover
  • Hot sleeper testers gave this pick high marks for
Cons
  • Thinner feel

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 gamechanger 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. It is actually 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. Woolroom's collection also includes a wool pillow and a mattress pad, which were popular among testers too.

Pros
  • Fluffy down alternative fill
  • Three fill lofts available
  • "Luxurious," according to testers
Cons
  • Testers did note that it made a bit of noise

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. 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.

How we test the best cooling comforters

line break

When Good Housekeeping textile pros evaluate cooling comforters, we test them in the Lab and have consumer testers try them out to give feedback on the comforters' temperature regulation capabilities. GH analysts look at each comforter hands-on to rate the construction and materials used. Then, we wash it according to its care label to evaluate any noticeable shrinkage or changes in appearance. The moisture management tester in the Lab places a small drop of sweat-like solution on the fabric and times how long it takes for the liquid to dissipate and into how large of an area, giving a score for the fabric's moisture-wicking abilities.

We also send comforters to hundreds of consumer testers to get feedback on comfort, temperature regulation, ease of putting in a duvet cover and more. Our last comforter test included 28 different styles and consisted of over 220 Lab and consumer tests. Using all of this data, we found the cooling comforters that are worth investing in.

How to choose the best cooling comforter

When it comes to cooling claims, there isn't a ton of regulation about what brands can say. Our fiber scientists see many products that promise to "stop night sweats or hot flashes," but these claims are largely unsubstantiated.

Cooling comforters should have excellent breathability and be lightweight, and may feature specific cooling technologies or moisture-wicking fabrics. If you're looking to stay cooler but still use a comforter, here's what you should look for:

✔️ Cooling technologies: The most common cooling technologies we see in bedding are Outlast and 37.5. Outlast stores and releases your body heat using "phase change material." (The brand describes it like ice melting to cool a drink.) 37.5 is triggered by humidity and wicks away sweat before it forms. These materials are your best bet if you're looking for the ultimate cooling comforter.

✔️ Lightweight down: Nothing is as fluffy as real down because the down clusters trap in air, but unfortunately for sweaty sleepers, this means they trap in heat as well. If you want to buy real down, opt for a lower fill power (a.k.a. the amount of space the down takes up). Anything with 600 fill or less is ideal for summer months because there's less air and therefore less heat being trapped. You can also find lightweight down alternative options.

✔️ Breathable and moisture-wicking features: If you sweat when you sleep, look for bedding with breathable designs and moisture-wicking capabilities. Some brands use merino wool, which has inherent wicking capabilities, while others may use a special construction that helps sweat spread and out and dry quickly. These types of features will help keep you dry, stopping night sweats in its track.

✔️ Be wary of "natural" claims: Some brands claim bedding is "naturally" cooling because it's made with "bamboo" or "eucalyptus" fibers. These types of fibers are actually "regenerated cellulose" fibers known as rayon or lyocell, meaning the wood pulp from different plants is dissolved in a chemical solvent before being pushed through an extruder to form fibers. (Check out Tencel for a more sustainable option.) These plants have been chemically altered to become fibers, so any inherent cooling benefit from the plant itself is actually no longer valid. Bottom line: These materials may still help keep you cool if they're lightweight and moisture-wicking, but it's not because they're "bamboo" or other so-called natural tree fibers.

✔️ Thickness: The thicker the comforter, the warmer it is, so a thinner comforter will help keep you cooler. However, it can be a tough balance to find a comforter that feels fluffy and luxurious without overheating. If you hate a thin comforter, we recommend all-season comforters with other cooling features for the best of both worlds.

Can you use a cooling comforter year-round or just in the summer?

dog

While cooling comforters are not as plush as all-season or heavyweight comforters, many people opt to use the same comforter for the whole year. Cooling comforters are thinner, so they're easy to pair with your favorite blanket or quilt to keep you cozy when the temperature drops. Many of the featured comforters here are also available in thicker styles, but if you live in an area with extremely cold winters, you may want to switch out your cooling comforter for a warmer option in the coldest months.
