Best overall

This comforter is breathable, cool-to-the-touch, and soft. The Rest Evercool Comforter quickly became a standout favorite during testing. It's one of the coolest comforters I've ever tested — my husband and I never woke up hot or sweating during the latest heat wave when we tested it. Incredibly lightweight, it feels soothingly light and airy, making it a joy to snuggle into with its soft, silky, and smooth nylon and spandex shell.

It's lightweight. It's reversible and comes in a variety of colors, including my personal favorite, aqua blue. Crafted from a blend of natural Tencel and Sorona, an eco-friendly fiber made from renewable, plant-based materials, the Rest comforter offers exceptional breathability and moisture-wicking capabilities. Washing it was a breeze since it's so lightweight, and it retained its shape perfectly without clumping, shrinking, or stretching.

It doesn't collect hair, so it's perfect for pet owners. The added benefits of a 30-night return policy (as long as it's in its original packaging), one-year warranty, Oeko-Tex certification, hypoallergenic properties, and pet friendliness make it even more appealing. I was pleasantly surprised to find no cat hair sticking to it — a bonus feature for pet owners.

But it's not perfect. It is strictly a comforter and does not have loops if you're looking to use a duvet cover, and it can slide easily when paired with silky cooling sheets. As someone who doesn't typically run hot, I woke up feeling chilly at least once. Unlike me, my husband, a hot sleeper, reported waking up feeling comfortably cool throughout our testing period. Overall, though, the Rest Evercool comforter lives up to its promise for hot sleepers, effectively managing sweat and moisture for a truly restful night's sleep.

Best value

Silk & Snow's comforter is puffy and breathable. The Silk & Snow Down Alternative Comforter was a delightful surprise in terms of both comfort and value. Opting for the lightweight version with 175 GSM (grams per square meter), the lower fill is ideal for those who tend to overheat at night. It strikes a perfect balance of cool and cozy. During our tests on warmer nights, it effectively dissipated heat, ensuring we woke up feeling comfortably warm but without any overheating issues.

It's an excellent value. Though I was initially skeptical about its affordability compared to other options, I was pleasantly surprised by its luxurious feel and the quality of its materials. The 100% cotton exterior provides excellent breathability, and the vegan microfiber fill gives it a plush, down-like sensation that is incredibly soft to the touch. It's also available in all-season and winter weights of 375 GSM and 500 GSM, respectively.

It fits perfectly in a duvet cover. It has retained its softness and plushness remarkably well after multiple washes. Practical features like built-in corner loops to keep the duvet insert in place and a handy storage bag added to its functionality. I recommend the Silk & Snow to anyone looking for a cozy, budget-friendly cooling comforter that doesn't compromise on quality.

Fluffiest

Despite its fluff, Slumber Cloud's comforter doesn't overheat. The Slumber Cloud UltraCool Comforter stood out as one of the fuller options, and its filling does wonders for temperature regulation while maintaining a substantial weight that you can feel. Compared to the others we tried, we loved how puffy and easy to maneuver it is. Throughout our testing, neither my husband nor I felt uncomfortably warm — the shell feels cool to the touch and effectively prevents heat buildup, keeping us comfortable all night long.

Both the shell and fill kept me cool. The shell, made of cooling nylon and spandex, not only feels light and fluffy with a beautiful silky soft finish but actively cools as well. The fiberfill impressively manages heat and moisture by absorbing, storing, and releasing it, effectively adapting to temperature changes. It kept us at a comfortable temperature without ever letting us get too hot, ensuring a cozy sleep experience throughout testing.

For something less puffy, check out the lightweight version. The comforter maintains its shape well, even after washing, and features convenient corner loops for securing it inside a duvet cover. While I also tested the thinner lightweight comforter version, I preferred the plushness of the UltraCool, though both were equally effective at temperature control. Overall, besides being a bit pricey, I didn't find many faults with it. I highly recommend the Slumber Cloud comforter for anyone in warmer climates seeking both plush comfort and excellent temperature regulation.

Best down

If you love the feel of down, this comforter is for you. The Lands' End Essential Down Comforter strikes just the right balance between warmth and breathability. Its lower 550 fill power makes all the difference in maintaining a plush feel without trapping heat, making it a good choice for hot summer nights.

It compresses nicely without feeling bulky. I loved the feel, but it might not appeal to those looking for a thicker, more plush comforter — though cooling comforters are generally thinner to minimize heat retention. The cotton sateen shell adds a touch of elegance and reminds me of the cozy luxury found in high-end hotels. We looked forward to snuggling into it every night during testing. What impressed us the most was its ability to stay light and airy despite the down fill.

But it's not the coolest comforter on the list. My husband, the hot sleeper, mentioned getting a tad warm at least once during testing, but he quickly cooled down after briefly uncovering to cool off before covering up again. The comforter features fabric loops for securing in a duvet cover and a handy storage bag. Overall, the Lands' End Essential Down comforter is a great option for those who prefer down fill. The comforter is both lightweight and substantial, making it suitable for warmer weather without overheating.

Best bamboo

Bamboo is one of our favorite materials for cooling bedding. Thanks to its natural breathability, moisture-wicking properties, and temperature control, the Cozy Earth Bamboo Comforter is the top pick for anyone seeking a natural bamboo option that feels cool-to-the-touch. Its luxurious bamboo viscose fabric shell and fill are crafted to naturally regulate temperature.

It's luxurious. Once unpacked from its beautiful canvas bag with leather straps, I was pleasantly surprised by how nicely it fluffed up. It molds around my body without trapping heat, providing a lightweight feel that keeps us cool and dry. Both my husband and I agree — it kept us refreshed, cozy, and feeling like royalty all night long. However, my husband, being the hot sleeper, did mention feeling a bit warm in the morning once during testing on a particularly humid night, though it was far from uncomfortably hot.

It's pricey and difficult to care for. The higher price tag forces me to be more conscientious about care and maintenance. Using a protective duvet cover is a must. Plus, since it's strictly spot or dry clean only, it's crucial not to risk washing it incorrectly if you're investing in this pricier option. Overall, it's an excellent choice for sleepers looking for naturally temperature-regulating bamboo that is responsibly sourced and suitable for year-round use.

Best hypoallergenic

This comforter is refreshing and hypoallergenic. If both allergies and overheating are among your primary concerns, the Sijo AiryWeight Eucalyptus Comforter can be a total game changer. I had one of the most refreshing and comfy sleep experiences using this comforter — even through warmer nights. The Tencel lyocell shell and fill are made from eucalyptus wood pulp, so it really feels super clean and fresh.

Eucalyptus is one of the best materials for hot sleepers. What really impressed me was how cool, silky, and soft it felt against my skin. The eucalyptus fibers are great at absorbing moisture and keeping heat at bay, so we actually stayed dry all night long. The comforter is treated with a silver ion antimicrobial treatment to make it extra clean. Plus, it's certified asthma & allergy friendly and Oeko-Tex approved to ensure that no toxic chemicals are found in the product.

It's pricey, but I think it's worth it. Though it is a bit of an investment, this hypoallergenic, cooling comforter can be worth it for its quality and eco-friendly design. It's a top pick for anyone who wants a high-quality, cooling and hypoallergenic comforter that is also comfy and kind to the environment.

Best lightweight

The Cool+ blanket is silky-smooth and lightweight. I've really come to love Coop's products because they consistently exceed expectations, and its Cool+ blanket is no exception. If you're a hot sleeper looking for a refreshing, cool-to-the-touch option, the Cool+ Blanket is a fantastic choice. Coop's cooling technology disperses more heat than bamboo, silk, or other popular synthetics. The breathable yet super-soft blend of nylon and spandex maintains an optimal temperature, allowing heat to dissipate throughout the night.

It cools quickly and wicks away moisture. I've used this comforter everywhere, from the bed to the couch, and it remains lump-free even after multiple washes. It's light, airy, and silky-smooth, making every night's sleep a delight — and yes, I've continued using it even after testing. The comforter effectively dissipated heat, maintained a comfortable temperature, and cooled down quickly.

It's similar to the Rest Evercool. There was a slight initial odor, which vanished completely after the first wash. Now, it's perfect. It's become one of my top favorites, offering exceptional quality and effectiveness at a fraction of the cost compared to other options. Deciding between this one and the Rest Evercool was tough. The Evercool is our overall pick because it's available in more color options, is hypoallergenic, and pet-friendly. But performance-wise, they come very close, both offering that refreshing, cooling sensation that hot sleepers seek for relief. It also does not have loops to be used with a duvet cover.

How we test cooling comforters

Our testing methodology

I tapped into my experience as a certified sleep science consultant and connected with experts like Nishi Bhopal, MD, a board-certified psychiatrist and sleep specialist, Alex Dimitriu, MD, dual board-certified in psychiatry and sleep medicine, and Chris Winter, MD, a neurologist and sleep specialist to evaluate the top cooling comforters on the market, focusing on these key factors that impact sleep quality:

• Sleep quality testing: I spent 7 consecutive nights personally sleeping with each comforter in a climate ranging from 75 to 90 degrees (during a heat wave), taking notes on comfort and feel, temperature regulation, breathability, heat retention, and cooling capabilities. Additionally, my husband — a natural hot sleeper — joined me in testing the comforters and provided his perspective on how well they performed.
• Materials and certifications: We took note of each comforter's material, looking for the most innovative and effective cooling technologies, and looked for certifications for quality.
• Cleaning: We carefully read and followed care instructions, caring for the comforters multiple times to assess long-term durability. Some comforters in this guide are dry clean only or can be spot-cleaned.
• Shape retention: We dragged the comforters from the bed to the couch and noted any lumps or flattening after washing and sleeping with them. Some, like the Slumber Cloud UltraCool Comforter, require light fluffing after washing.
