I love the fluffy feel of a plush comforter, but also want a comfortable body temperature all night long. Luckily, cooling comforters are designed to trap less heat, and many even use specialized cooling technology, which is game-changing for users experiencing night sweats or menopausal hot flashes. What's the best cooling comforter? Our top-tested pick is the REST Evercool Cooling Comforter. With an immediate cool-to-the-touch feel, this comforter easily wicked away moisture in Lab tests and was a favorite among hot sleeper testers. For a more affordable buy, the Elegear ArcChill 3.0 Cooling Comforter is a great value at around $60 for similarly cool fabric with a lightweight fill. The Good Housekeeping Institute Textiles Lab has tested over 70 different comforters to find the best picks for your coolest sleep yet. We regularly test bedding of all kinds from down comforters to duvet inserts. In the Lab, we evaluate design and construction and vet all cooling claims and technologies. We also send cooling styles to consumer testers who identify as hot sleepers to evaluate real-world performance. Cover material: Nylon, spandex | Fill material: Down alternative (Sorona polyester and Tencel lyocell) | Cooling features: Moisture-wicking and cool-to-the-touch cover, lightweight fill Amongst all the cooling comforters we tested, this cooling comforter from Rest reigned supreme. A game-changer for sweaty sleepers, it actually feels icy cold to the touch. Its silky-smooth performance fabric aced our moisture-wicking evaluations in the Lab, easily wicking away a sweat-like solution and showed no signs of wear after laundering. We appreciated its thin, lightweight feel, which helps prevent overheating and keeps you cool and dry. Still, it might feel too thin for some; it's thinner than your typical all-season comforter despite the smooth feel. TESTING NOTES: Our testers gave it perfect scores for keeping them at a comfortable body temperatures. One even described it as "soft and cool (almost icy even)," and said, "it provided much-needed relief in hot weather." 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!” READ OUR FULL REVIEW: Rest Evercool Cooling Comforter Cover material: Nylon/spandex and polyester | Fill material: Down alternative polyester | Cooling features: Moisture-wicking and cool-to-the-touch cover (one-side), lightweight fill This lightweight, double-sided comforter is designed for year-round use (aside from an extra cold winter). It has a smooth, cool-to-the-touch side which quickly wicked away night sweats in our tests and a buttery soft, brushed back, which helps provide added warmth during chilly nights in the spring or fall. This pick is meant to be used on its own (without a duvet cover), but you can pick between a few solid colors. And while you can launder it in a washing machine, make sure to hang it to dry in the shade. TESTING NOTES: It was a hit amongst our testers for its cool, smooth outer fabric. One said, "As a menopausal woman, feeling the coolness of the comforter when a hot flash occurs was so welcoming and relieving." Others liked how light it felt. One user shared, " I love how soft and light it is...not heavy or bulky, which I love." Note that the brand recommends moving the comforter around to maintain its cool feel or using a fan, which not all testers loved; some found it disruptive and wished the cooling properties lasted longer. Cover material: 89% Cooling nylon, 11% spandex jersey | Fill material: Outlast-infused down-alternative fiberfill | Cooling features: Outlast temperature-regulating technology, moisture-wicking cover 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 nylon and spandex jersey cover has a silky feel for an extra cooling feel — though some testers said it felt too slippery. TESTING NOTES: 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. RELATED: The Best Cooling Pajamas Cover material: Lyocell | Fill material: Down-alternative lyocell | Cooling features: Moisture-wicking and cool-to-the-touch cover, lightweight fill 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 sustainable 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. TESTING NOTES: 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 feel, one tester said this comforter was "significantly cooler than my down duvet." Another said, "The comforter feels very quality, luxe and hotel-like." The brand offers a generous free trial period that allows you to try the Buffy for seven nights before buying. READ OUR FULL REVIEW: Buffy Comforter Cover material: 100% organic cotton | Fill material: 70% down and 30% wool | Cooling features: Temperature-regulating fill 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 for year-round use. While down is known for its ability to trap warmth, wool stands out for its natural temperature-regulating qualities. It uses baffle-box construction and has convenient corner loops, which help keep it in place in a duvet cover. Plus, it's machine washable! TESTING NOTES: 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. RELATED: The Best Duvet Inserts Cover material: 100% extra-long staple cotton | Fill material: Microfiber | Cooling features: Lightweight and super-lightweight options If you want a fluffy comforter but have a down sensitivity, opt for a down-alternative pick instead. This top-tested style from Crane & 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. TESTING NOTES: 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." One called it perfect for pet owners and shared, "I thought I would have to wash it sooner because we have a dog that sleeps on top of the comforter, but there is no evidence that we even have a dog." Still, some testers experienced a bit of a crinkling noise when using it without a duvet cover. RELATED: The Best Down Alternative Comforters Cover material: Cotton | Fill material: Wool | Cooling features: Natural temperature-regulating properties of wool 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 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. TESTING NOTES: This comforter received high marks for helping testers maintain a stable body temperature. 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, but users didn't mind that in our tests. Many even shared that they liked the weight. Cover material: 80% polyester and 20% 37.5 performance polyester | Fill material: Down alternative: 80% polyester and 20% 37.5 performance polyester | Cooling features: 37.5 cooling technology in both the cover and fill 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. 37.5 technology absorbs heat to help to prevent night sweats from occurring. It's also generously sized, which is a key concern for users in our tests, for a more substantial, luxurious feel and has corner loops for pairing with a duvet cover. TESTING NOTES: While we're still in the process of testing this comforter, we're impressed by how lofty it felt compared to our other picks. One pregnant tester also shared that she slept cooler under this comforter than other comforters she's owned. Note that this pick uses box stitching (not baffle-box construction) so fill may shift a bit during use. Cover material: 100% cotton | Fill material: Down | Cooling features: Lightweight fill If you like the classic fluffy feel of real down but run hot, look for a lightweight style with a lower fill power. This pick from Brooklinen comes in three different fill options, so you can choose the right one for you. The lightest fill has a 650 fill power for an airy feel. It uses baffle-box construction, which helps keep the fill in place and also comes with a generous year-long return period. Note that this pick is recommended spot-clean and dry clean only. TESTING NOTES: In our tests, this comforter felt airier and lighter than others we tested, with less loft to trap hot air than typical heavy styles. Our testers agreed: One said, "it feels like I’m sleeping under a very light cloud." Another user, who tried the All-Season version, remarked, "It felt so plush and like being wrapped in a cloud! I couldn’t believe how lightweight it was, unlike some down comforters that can be heavy." If you prefer to use one comforter year-round, the All-Season model earned high scores from our testers for keeping them at a comfortable body temperature. RELATED: The Best Down Comforters When Good Housekeeping Institute textile pros evaluate cooling comforters, we test them in the Lab and have consumer testers try them at home 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 (pictured here) in our 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 who identify as hot sleepers to get feedback on comfort, temperature regulation, the ease of putting it into a duvet cover and more. Our latest comforter tests have included nearly 70 different styles and consisted of over 400 Lab and consumer tests. Using all of this data, we found the cooling comforters that are worth investing in. 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 be lightweight and have excellent breathability. They may also 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. ✔️ Lightweight fill material: ✔️ Cool-to-the-touch cover: If you sweat when you sleep, look for a comforter cover with a breathable feel and moisture-wicking capabilities. Tencel lyocell and synthetic materials like nylon wick away moisture easily for a cooler feel. Covers with cooling technologies like 37.5 and Outlast can help regulate your body temperature too. Cotton has a soft, natural feel that is popular in bedding, but it absorbs moisture, so it can feel sweaty for hot sleepers. ✔️ 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 no longer applicable. 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 tree fibers. What type of comforter is best to keep you cool? The coolest comforter will utilize cooling technology like 37.5 or Outlast, use moisture-wicking materials in the cover and be thin and lightweight. Comforters can have a cooling effect with both down and down-alternative fills as long as they're not too thick. Do cooling comforters really work? Yes! Cooling comforters can help make your bed feel cooler at night, especially if you're replacing a thick, high-fill power comforter. However, cooling comforters aren't miracle workers and if you're sleeping in a super hot environment or suffer from hot flashes, it may not be a complete solution. How do I keep the cool effect when using a duvet cover? Pairing your cooling comforter with a cooling duvet cover is a great way to enhance its cooling benefits. Opt for lightweight, moisture wicking materials. A great choice is the Buffy Breeze Duvet Cover, which is made with moisture wicking Tencel and it's a Good Housekeeping Seal holder.
