Beyond finding the right room temperature for sleep, taking steps like investing in cooler pajamas, and reconsidering your sheets are all great ways to keep your body temperature down, similar to the way our bodies evolved over time. On top of all of these shifts, adding the best cooling comforters to your bed setup is a surefire way to stay cool even as temperatures rise (either from the shift to summer or a radiator on full-blast in the middle of winter). Below, uncover the best cooling comforters that can help keep you chill all night long and finally get the zzz’s you need. Materials While finding a nontoxic or sustainably sourced product isn’t always so simple in the sleep space, the cooling comforter category comes stocked with good options. Although these more eco-friendly options often come at a higher price than synthetic blends, they’re worth the extra cash when it comes to snoozing safely. After all, you spend more than a third of your life in bed, which means you want to be surrounded by materials you can trust. Weigh the pros and cons of each material. Along with linen, the best cooling materials tend to be silk; select cottons, like percale and Supima; and tree fibers, such as bamboo, eucalyptus, and pine. When sourcing these materials responsibly, keep an eye out for certifications, like GOTS organic labels or a Tencel yarn with a closed-loop chemical process. Care Caring for your comforter is important for extending its lifespan, especially considering how expensive they can be. If you’re someone who prefers to throw things in the washing machine over sending them to the dry cleaner, you’ll want to read the care instructions carefully before buying and consider machine-friendly materials, like bamboo Tencel. Sleep trials & returns If you struggle to get comfortable at night, you’ll want to prioritize a brand that offers a generous in-home sleep trial and a solid return or exchange policy. This will help make your life considerably easier if the weight or material of the comforter you choose ends up not working out for your specific needs—especially because quality comforters typically come at a higher price tag. Consider your company So, you sleep hot—but what about your bed buddy? If you share your bed with a partner, a lightweight comforter might not be warm enough for them. A few brands offer an “All-Season” option that can be accommodating for sleepers with different temperature preferences. If the company has a decent exchange policy, it might be a good place to start before going straight to the lightweight model. Cozy Earth’s Bamboo Comforter is an oversize yet lightweight option that’s perfect for folks who sleep in a bigger bed. The extra length ensures even those who run hot can keep their toes tucked under the covers throughout the night. Available in two fill amount options (“standard” or “extra”), the duvet also comes in two breathable material types: bamboo viscose or mulberry silk. Both options come in a reusable duffel bag and are machine washable on gentle (Cozy Earth says to avoid spin cycles and air dry if possible). Regardless of the material selected, the comforter shouldn’t pill or clump with use, but Cozy Earth offers a generous trial period and a 10-year warranty, if you have any issues. Plus, the brand is known for having excellent customer service. What customers say: This comforter has 4.9 out of 5 stars after more than 600 reviews—and it’s also backed by Oprah if that’s a selling point for you! Reviewers say it’s a great breathable option that provides cozy yet cool sleep. One person writes, “The bedding is the most comfortable I’ve ever had. It comes out of the dryer without wrinkles, is neither too hot nor too cold, and is a generous fit on my king-size bed.” On the con side, a few folks warn that because this comforter is oversize it may not fit in all duvet covers. Eco-friendly mattress company Avocado is known for its sustainability efforts, and the brand’s bedding is no exception. This duvet insert uses natural alpaca fibers for a fluffy yet breathable interior. Similar to wool, alpaca fiber is known for being moisture-wicking and good for regulating temperature. The shell is 100% GOTS-certified organic cotton percale, and it’s available in two different weight options: lightweight, which Avocado says is best for warmer months and climates, and all-season, which is thicker and warmer. Hot sleepers will likely prefer the first option, but both include the same temperature-regulating materials. What customers say: This comforter doesn’t have a ton of reviews (just over 60), but a majority of folks give it a positive rating. It gets great comments from hot sleepers and people who live in warmer climates. One reviewer writes, “Nice weight, it really does breathe better than cheaper synthetic duvets. While adding warmth without overheating us ‘warm sleepers.’ Will simply add a blanket for cold weather. Great quality (stitching, etc.) as all items from Avocado.” Beyond making a quality comforter, staying eco-friendly is at the center of everything Buffy does (which definitely pops them near the top of our list). This lightweight comforter uses sustainably sourced eucalyptus Tencel for both the shell and interior fibers, and the entire thing is compostable! It also uses a unique vertical stitching to ensure even fill distribution with loops on every corner to attach to your duvet cover (which Buffy suggests, as this comforter isn’t machine washable). We also love that while the brand focuses on sustainability and quality, this comforter is not a total splurge with prices starting under $200. Plus, Buffy offers a discount if you bundle the Breeze Duvet with the Breeze Comforter to make a set (one for winter; one for summer). What customers say: The Buffy Breeze has more than 6,500 reviews with just under a 5-star rating. Hot sleepers give it excellent reviews for breathability and softness. One reviewer raves, “Wow! This is what dreams are made of! I run hot and am a sweaty sleeper and this thing solves all this. Instead of blasting the AC, I can keep it as is.” A few folks say they wish it was fluffier, but Buffy does have a warmer, cozier option that uses similar materials called the Buffy Cloud. Merino wool is known for its moisture-wicking properties, which is exactly why this pick from Casper is called the “Humidity Fighting Duvet.” Inside the 100% cotton shell is sustainably sourced down and a thin layer of merino wool. Casper says this helps naturally wick away moisture—great news for night sweaters! Another great perk is that the design has many horizontal chambers to better distribute the down and wool throughout the comforter, making it similar in design to your favorite puffy jacket. Based on the time of year that you need to use this cooling pick, it comes in two fills: lightweight and a thicker mid-weight option. Better yet, it’s machine washable! What customers say: One shopper gushes, “I’m amazed at how light this duvet is yet it keeps me warm without sweating like I did with my old duvet. And did I mention how light it is? I move a lot before I go to sleep and while I’m sleeping. The Casper duvet doesn’t make me feel weighed down and restricted like I did with my old cover.” The only con we saw in the reviews was that the crispness of this comforter can be kind of noisy—something to consider if you move around a lot in the night. Brooklinen’s down comforter comes in three different weight options, all of which use the same 100% cotton sateen shell. The lightweight option is—as the name suggests—the lightest and most breathable option of the three and uses recycled down feathers for the fill. If you end up finding it too lightweight, you can exchange within 365 nights for the all-season, which has a little more fluff and uses ethically sourced duck feathers. Each model has baffle box quilting to keep the fill evenly distributed and corner loops for tying into your duvet cover. Just beware that it’s not machine-washable. However, the exterior is treated with ultra-fresh antimicrobials to prevent a stench. What customers say: With over 117,000 reviews and 4.7 out of 5 stars, Brooklinen’s Down Comforter is a hit. One reviewer says, “I look forward to getting into bed with this soft-as-a-cloud comforter! I am VERY choosy when it comes to bedding and have tried many brands. I purchased the lightweight comforter. It is perfect for my husband all year round and perfect for me with a blanket on my side for colder nights.” Note that one potential downside of this comforter (and most down comforters) is that it’s not machine washable and is best shaken out outdoors or sent to the dry cleaner.
