“Our body temperatures fluctuate during the day, falling around 10 p.m., signaling your brain that it is time to sleep,” says Dr. Long. “So, anything that facilitates or mimics your body’s natural nighttime drop in temperature will help you sleep—this includes choosing breathable bedding pieces that help regulate your body temperature.” To find the best cooling comforters, we researched a variety of picks, keeping in mind the shell material,  fill material, and care instructions. We also consulted Dr. Daria Long and Susan Lazor, associate product merchant at The Company Store, and Susan Wojewoda, president at Scandia Home, for additional insight. Overall, we chose the Buffy Breeze Comforter as the best cooling comforter. In addition to being made from breathable, eco-friendly eucalyptus, it also has a unique weave that keeps the fill from clumping and can be used with or without a duvet cover. Here are the best cooling comforters. Keep in Mind: The comforter is dry clean only, so it’s not as low maintenance as some other options. The comforter comes in three sizes, each of which has loops on each corner to help keep it in place when using it with a duvet cover.  It also has a unique wave-stitch technology that keeps the fill materials in place so that your fill doesn’t end up unevenly distributed or in clumps.  While it can be used on its own, you can add a more decorative duvet cover for an additional cost. Buffy has a generous return policy, giving all buyers a seven-day trial period to decide if they are happy with the comforter before buying it. Once you buy it, you’ll still have up to 100 days to get a full refund if you’re unsatisfied. It does have to be dry cleaned, however, so keep in mind that’ll add an additional cost each time you want to clean it. Price at time of publish: $279 Fill Material: Tencel lyocell | Shell Material: Tencel lyocell | Washing Instructions: Dry clean only Keep in Mind: This profile is relatively thin, so it may not be the best option if you prefer a fluffier comforter. The blanket is offered in three sizes and is machine washable, so it’s easy to keep in good shape. Plus, the shell contains lyocell fibers that are breathable and help to absorb excess moisture, so you stay cooler while you sleep. The blanket is offered in white and while it can be used on its own, you can also use it with one of Ikea’s duvet covers for extra protection and longevity. Plus, you can return opened products to Ikea within 180 days for a full refund. Price at time of Publish: $47 Fill Material: Polyester and viscose | Shell Material: Lyocell and cotton | Washing Instructions: Machine wash Keep in Mind: You have to use a duvet cover to validate the brand’s extended warranty. The two fill options are 100% viscose made from bamboo or 100% mulberry silk, each of which is cooling and breathable. The shell is also made from bamboo fiber, which is soft, moisture-wicking, and great for temperature regulation. While the comforter also has a slim, non-bulky profile, it has an option for adding extra fill in in case you want something a little fluffier. To keep the cooling comforter in good shape, you can either spot clean, dry clean, or machine wash on the rinse cycle only. To prevent the filling from clumping, the brand also recommends using 2-3 dryer balls as well. It’s also worth noting that while it can certainly be used on its own, it must be used with a duvet cover to validate the brand’s extended warranty. Although the comforter is an investment, you’ll rest easy knowing you don’t have to commit to it right away. In fact, Cozy Earth offers a 100 days guarantee so you can try it out for over three months before deciding if you want to keep it. Price at time of publish: $399 Fill Material: Bamboo or silk | Shell Material: Viscose bamboo | Washing Instructions: Spot clean, dry clean, or machine wash on rinse cycle only Keep in Mind: The comforter is designed to be used without a duvet, so it may not be for you if you don’t want a colorful comforter. While this cooling comforter may feel like silk, it’s way lower maintenance—you can just throw it in the washing machine, no dry cleaning needed.  It’s also pill and snag-resistant, so you don’t have to worry about it looking worn after a few months of use, which is especially important considering it’s meant to be used without a duvet cover. The cooling comforter is filled with a hypoallergenic filling called Sorona, so it’s a great choice for those with allergies. Not only is it breathable and quick-drying, but Sorona is also made partially from plants making it more sustainable than some other fills.  Plus, no harsh chemical or allergen additives are used to make the comforter, making it ideal for people with sensitive skin. The comforter is reversible, so you can switch between two shades of blue or gray, depending on which color you choose. Just keep in mind that it’s only offered in two color options and isn’t meant to be used with a duvet cover, so it may not match every bedroom style. The brand does offer free shipping, a 30-day sleep trial, and free returns, however, so you can try it out in your space. Price at time of publish: $199 Fill Material: Evercool | Shell Material: Sorona | Washing Instructions: Machine wash Keep in Mind: It’s more expensive than other options on the market. Plus, the king size is only offered in one weight. The blanket is offered in three sizes, each of which is a different weight. Part of what makes this pick one of the best cooling comforters is that glass microbead fill is centered instead of edge to edge, so you’ll get the weight where you really need it. The glass microbead fill is secured via tight quilting, so you don’t have any unwanted bunching or pooling.  Depending on the size, there are also 10-12 tie loops to attach a duvet cover easily. Unlike some other picks, the blanket is machine washable and can be dried on low heat, so it’s fairly low maintenance. If you’re not sure what size and weight are best for you, however, Baloo offers a quiz to help you choose, as well as easy returns. Price at time of publish: $279 Fill Material: Cotton | Shell Materials: Cotton | Washing Instructions: Machine wash Keep in Mind: It’s only offered in two sizes, so it may not work for every bedroom. Dry cleaning is also recommended, so it’s more high-maintenance than other picks. The cooling comforter is made with a lyocell-based fabric called Outlast in the lining that traps the heat to cool you off but then releases it when you cool down so that you always are at that just-right temperature.  The outer layer of the comforter is made from cotton, with a down-proof finish, so you don’t get all those pesky feathers poking you in the middle of the night. To secure the duck down in position, the Slumber Cloud Down Comforter has 12-inch quilt boxing. The detail also happens to give it a more polished look, so you can use it without a duvet should you choose to use it without a duvet cover. This 10-pound comforter is an ideal weight for year-round use, so you won’t have to worry about switching out comforters or blankets when the seasons change. Price at time of publish: $279 Fill Materials: Duck down | Shell Materials: Cotton | Washing Instructions: Spot clean or dry clean Keep in Mind: A duvet cover is recommended to extend the life of this comforter.

It’s filled with bamboo lyocell and made with a bamboo shell as well. The shell features a breathable weave that contributes to the overall cooling factor and it’s also hypoallergenic, so it’s a great pick for those with sensitive skin. It’s worth noting that the comforter is a bit more expensive than other picks and it’s recommended you dry clean the comforter, which adds an additional cost. However, Ettitude offers a 30-night sleep trial, so you can try it out and see if it’s the best cooling comforter for your bedroom.

What to Know About Cooling Comforters Before Shopping

Fill Material

There are a few key points to consider when it comes to filling materials for cooling comforters. First,  do you want a natural or synthetic material? Down is a natural, incredibly soft, and fluffy material but often not the best option for those who want an extreme cooling option since it can be more insulating than other materials, despite being breathable.  It can also be an issue for allergy sufferers. Cotton and wool are also good options for temperature regulation and breathability while being more affordable than down. Silk will provide that soft and airy fill but at a much higher price point.  Synthetic materials like polyester or rayon will be much more budget-friendly than down and can work as down alternatives to mimic the fluffiness of feathers.

Shell Material

To choose the best cooling comforter for you, it’s also important to look at the shell material, as that contributes to how cool it will be. “Breathable comforter shell materials include both conventional and organic cotton,” says Lazor. “Other breathable alternatives are blends that include rayon made from bamboo and Tencel Lyocell, made from eucalyptus.”

Washing Instructions

Instructions for cleaning vary depending on the cooling comforter and its material. Before you purchase a cooling comforter, consider if you’re willing to dry clean it as it’ll take more time and make for an additional cost. Otherwise, there are many machine washable picks that are lower maintenance.

Your Questions, Answered

Are duvets cooler than comforters?

Duvets are just an insert and cover combined, while a comforter is just one piece. In terms of cooling capabilities, the style of the comforter isn’t what’s going to make a difference in your sleep, according to Lazor. “Duvets (duvet inserts) and comforters are basically the same,” Lazor says. “One is not cooler than the other; rather their warmth level depends on the weight you choose.”

Do down comforters keep you cool?

While down comforters can keep you cool and are generally breathable, it’s important to look for options with a lower fill power, especially for warmer months. “Down, a natural by-product from geese or ducks, has insulating properties,” says Wojewoda. “Down is comprised of clusters, and the larger the clusters, the warmer the down. Fill power is the industry’s metric for measuring the insulating properties of down. The higher the fill power, the larger the clusters; the larger the cluster, the more warmth it will provide.”
