The Best Cooling Comforters

The Luxome ClimaSense Comforters proprietary fill dissipates body heat effectively while also providing insulation for cold weather. The standout feature of the Luxome ClimaSense Comforter is its proprietary polyester fill that’s engineered to adapt to the sleeper’s body temperature throughout the night. Encased in a cotton-polyester blend cover, the comforter is available in full/queen and king/California king sizes. 

The Luxome comforter is thick and fluffy yet breathable, and our testers noted that its cotton and polyester cover feels smooth to the touch. The proprietary polyester fill is designed to respond to humidity and body temperature changes, preventing hot sleepers from overheating while still warming cool sleepers.

Thanks to its superb temperature regulation, the Luxome ClimaSense Comforter is a great choice for hot sleepers who want a cover with a thick, fluffy loft. The comforter is oversized to ensure full coverage for couples, and its baffle box design creates separate compartments for the fill to promote shape retention.  Luxome offers free shipping in the contiguous U.S. and a 30-night sleep trial. The company recommends spot-cleaning, as the comforter cannot be cleaned in a normal washing machine.

The Rest Duvet’s Evercool Comforters design is particularly well suited to extremely hot or humid environments, and people who need help cooling down at night. The Evercool Cooling Comforter from Rest Duvet earns its name thanks to a proprietary shell fabric engineered for temperature and moisture control. Evercool consists of 90% nylon and 10% spandex, so the material is exceptionally stretchy and durable. Down alternative fill made of Tencel and plant-based Sorona fibers provides additional cooling, as well as some welcome softness.

Evercool fabric feels cool to the touch at all times. Thanks to the stretch-nylon fabrication, the shell is also strong and elastic with excellent shape retention. Synthetic down alternative fill makes the comforter light and plush without triggering symptoms for people who are allergic to real down or using animal-based materials. A thin profile also means excessive heat buildup shouldn’t be a problem — but on the flipside, the comforter may not provide adequate insulation during chillier times of the year. You can choose from three solid colors and two dual-tone palettes.

The comforter’s shell and fill are composed of materials that provide next-level cooling.   Another thing our team enjoyed about the Evercool is its low-profile design — it’s slimmer and lighter than most competing comforters, and this helps ensure consistent thermoregulation in hot and humid conditions. The material is also remarkably stretchy, so the comforter should retain its shape wash after wash. That said, larger sizes may be too big for your household washing machine.

The Cozy Earth Bamboo Comforter is made from bamboo-derived viscose, this thin comforter is both comfortable and durable. Our testers noted that its lightweight design provides cozy warmth while preventing overheating. Both the cover and fill of the Cozy Earth Bamboo Comforter are made of viscose derived from bamboo. The construction takes full advantage of the material’s extra soft breathability and natural temperature regulation. Featuring a thinner loft than many down and down alternative fills, the comforter is available in twin, queen/full, and king sizes. For an added cost, buyers can opt for additional fill.

The bamboo-derived viscose cover feels sleek and cool, allowing for abundant airflow. While the Cozy Earth Bamboo Comforter’s profile is thinner than many down comforters, our testers described it as one of the fluffiest they’ve tried. Also, its temperature regulation makes it versatile and able to accommodate different types of sleepers year-round. 

The Cozy Earth Bamboo Comforter delivers silky comfort, first-rate cooling, and enough adaptability for a wide range of weather. For people in colder climates, Cozy Earth offers an extra-filling option for more warmth. The comforter includes free shipping throughout the U.S., a 100-night sleep trial, and a 10-year limited warranty. Cozy Earth recommends spot-cleaning and dry-cleaning over machine-washing.

The aptly named UltraCool is packed with Clima Dry fibers that feel cool to the touch and dissipate heat from your body, resulting in comfortable sleep any night of the year. The Slumber Cloud UltraCool Comforter nicely toes the line between cooling and coziness, creating a covering that feels comfortable throughout the year. Our team enjoyed the UltraCool for its plush fill and sleek, quilted shell — both components contribute to the comforter’s thermoregulating properties, but also ensure coziness during colder times of the year.

Clima Dry down alternative fibers create a plush, lofty feel akin to real down, but without triggering allergies or using animal-based products. A soft and stretchy shell encases the comforter, with diamond-shaped baffles to evenly distribute the fill. Weighing more than 7 pounds and measuring 1.5 inches, the UltraCool is fairly heavy and thick for a cooling comforter.

Our team was greatly impressed with the UltraCool’s temperature-regulating properties. The Clima Dry fill produces bursts of cooling that can significantly improve your comfort if you’re a hot sleeper. The shell also adds breathability and moisture control to the design, as well as durability and shape retention — the stretch-nylon fabrication holds up very well over time.

Filled with a proprietary fiber that’s engineered to regulate temperature, the Sijo TempTune Comforter is designed to help sleepers maintain an ideal body temperature regardless of climate. The breathable Tencel and nylon cover wicks moisture, making it an excellent choice for sleepers prone to night sweats. In the Sijo TempTune Comforter, proprietary CLIMA fibers, polyester, and Tencel combine to create a unique fill that regulates temperature well enough for year-round use. Available in full/queen and king/California king sizes, this soft and lightweight model is a comforter for all seasons.

Overall, the Sijo TempTune Comforter closely mimics the fluffy loft of down. However, when body temperature changes, the fill absorbs or disperses heat. The moisture-wicking Tencel and nylon shell feels sturdy yet soft and cool to the touch.

The standout feature of the Sijo TempTune Comforter is its proprietary CLIMA fibers, which are designed to keep the sleeper’s body temperature between 82 and 89 degrees Fahrenheit — the ideal sleeping temperature, according to Sijo. It works for mild summers thanks to its lightweight feel and cooling properties, but because of its ability to store and release heat, it performs well in the cold too.  The comforter includes a seven-night sleep trial and free shipping in the U.S. Sijo recommends spot-cleaning or dry-cleaning, as it is not machine-washable.
