Written by Garen Glazier

Reviewed by Dr. Michael Breus

Expert Tested

Cooling comforters give hot sleepers the cozy feel of a traditional comforter while helping to regulate body temperature. Like normal comforters, they consist of a fabric shell and an insulating fill. However, in order to reduce heat retention, they are constructed from breathable materials like cotton, down alternatives, and fibers derived from bamboo and eucalyptus. 

We’ll share our picks for the best cooling comforters in several key categories. We’ll also delve into types of cooling comforters, factors to consider when choosing one, and other ways to stay cool at night.

  • Proprietary polyester fill is engineered for temperature control
  • Blended cotton and polyester cover is smooth and breathable
  • Oversize design provides generous coverage for co-sleepers


  • Not machine-washable
  • Polyester fill is less durable than down

Sleep Doctor’s Take

The Luxome ClimaSense Comforter is a plush and versatile model that impressed our testers with its exceptional temperature regulation. Its 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. 

How Does it Feel?

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.

Why We Like it

Best Value

Rest Duvet Evercool Cooling Comforter

Buy From Rest Duvet
Cover Material:

EverCool fabric (90% nylon, 10% spandex)

Fill Material:

Tencel and Sorona fiber fill




Twin/Twin XL, Full/Queen, King/California King


  • Proprietary Evercool fabric is breathable, ultra-stretchy, and long-lasting
  • Above-average moisture control for those prone to night sweats
  • Available in three sizes and five color palettes


  • May not provide enough insulation on chilly nights
  • Commercial washing machines may be needed for larger sizes

Sleep Doctor’s Take 

Rest Duvet’s Evercool Comforter is engineered to resist heat retention in any climate and wick moisture away from your body. This 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.

How Does It Feel?

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.

Why We Like It

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.

Best luxury

Cozy Earth Bamboo Comforter

Buy From Cozy Earth
Cover Material:

100% viscose from bamboo

Fill Material:

Viscose from bamboo fibers




Twin, Queen, King


  • Extraordinarily soft and breathable
  • Bamboo-derived viscose delivers superb temperature regulation
  • Generous 100-night sleep trial and 10-year limited warranty


  • Thinner profile than traditional down comforters
  • Machine-washing is not recommended

Sleep Doctor’s Take 

Our testers loved the light and silky feel of the Cozy Earth Bamboo Comforter. 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.

How Does it Feel?

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. 

Why We Like it 

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.

Best Temperature Regulating

Slumber Cloud UltraCool Comforter

Buy From Slumber Cloud
Cover Material:

89% nylon, 11% spandex

Fill Material:

Clima Dry down alternative fibers




Twin/Twin XL, Full/Queen, King/California King


  • Clima Dry down alternative fibers crate bursts of cooling in response to body heat
  • Stretch-nylon shell is durable and resistant to shape loss
  • Diamond baffle boxes evenly distribute the fill and minimize clumping


  • Not ideal for people seeking a thin, lightweight comforter
  • More expensive than the average comforter

Sleep Doctor’s Take 

Slumber Cloud’s thickest, heaviest comforter is also the brand’s best option for beating the heat. 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.

How Does It Feel?

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.

Why We Like It

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.

Best all-season

Sijo TempTune Comforter

Buy From Sijo
Cover Material:

Tencel and nylon blend

Fill Material:

CLIMA cooling tech fiber, Tencel, polyester




Full/Queen, King/California King


  • Fill contains fibers designed to maintain optimal body temperature year-round
  • Tencel and nylon cover wicks moisture
  • Designed with loops for attaching a duvet cover


  • Not machine-washable
  • Down alternative fill is less durable than down

Sleep Doctor’s Take 

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.

How Does it Feel?

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.

Why We Like it 

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.

Why You Should Trust Us

Our diverse testing team rigorously evaluated dozens of comforters to determine the best options for cooling and comfort. We thoroughly assessed key factors like breathability, moisture-wicking ability, and temperature regulation across a wide range of materials and price-points. We continuously update our picks so readers have the most up-to-date recommendations.

What is a Cooling Comforter?

Cooling comforters help sleepers maintain an optimal sleeping temperature through materials that emphasize breathability, moisture-wicking capabilities, and temperature regulation. 

Breathability refers to how much airflow the comforter allows. More airflow means faster heat dispersion and cooler sleep. Moisture-wicking fabrics pull sweat away from the body so the comforter doesn’t become damp. 

Temperature regulation describes the comforter’s ability to adapt to body temperature. Some cooling comforters absorb and release excess heat when the sleeper gets too warm, but still insulate at cold temperatures. 

Thanks to these characteristics, cooling comforters can greatly improve quality and consistency of sleep for hot sleepers, people who live in warm climates, and those who sleep with a partner or pet. 

Why Should You Use a Cooling Comforter?

Cooling comforters help prevent sleep interruptions and restlessness caused by changes to body temperature. Like traditional comforters, they also add a cozy drape over the sleeper for extra comfort, and they can serve as a cover to prevent spills and stains on the mattress. 

Hot sleepers and those in warm climates especially benefit from their temperature regulation. However, because many cooling comforters adapt to different body temperatures, they are also useful for couples and people who sleep with pets.

Comforters vs. Duvets

While comforters and duvets perform the same function, they differ slightly in their construction and care. Comforters consist of a fabric shell with fill, and are able to be used as-is. Duvets include a fluffy insert with a thinner removable cover meant to be washed regularly. Some comforters are designed with loops for attaching duvet covers.


Ideal For

  • Sleepers who like the simplicity of a single-piece bed cover
  • People who don’t mind washing bulky items
  • People who prefer to wash the cover only
  • Those who like having the ability to switch out inserts or covers

Best Types of Cooling Comforters

Quality cooling comforters are constructed from breathable materials to help the body disperse heat. We’ll detail different breathable fabrics and explain how they perform in cooling comforters. 

Down and Down Alternative 

Down fill is derived from the fluffy clusters found underneath the outer feathers of ducks and geese. Down is light yet compressible, and it’s often associated with luxury and higher price-points. However, it also has a tendency to trap heat, which makes it excellent for cold climates but less common in cooling comforters. 

Down alternatives use synthetic or semisynthetic materials to mimic the light fluffiness of down. Quality down alternatives feel as soft as the real thing, but they may be constructed from a more breathable material or have added cooling agents. Down alternatives are generally less durable than real down but come at a lower price-point. 


Breathable and crisp yet still soft to the touch, cotton has long been a standard for warm weather bedding. Cooling comforters that use it are generally more affordable than those that use other natural materials. However, comforters made from cotton may not insulate as well in cold weather.


Silk has a smooth, airy feel associated with luxury, and it’s an excellent temperature regulator. The supremely breathable material resists heat buildup but still provides insulation when the temperature drops. Silk comforters are more difficult to care for and usually sell at a premium price-point.


Many comforters use lyocell fibers derived from eucalyptus plants because they create a soft, breathable fabric that wicks moisture and rivals the smoothness of silk. Eucalyptus-based fabrics are considered more sustainable since the plant requires less water than cotton to grow.  


Known for its breathability, moisture-wicking properties, and temperature regulation, wool is a popular material for comforters because it also keeps sleepers warm in cold weather. However, wool is heavier than other breathable fabrics, and cooling comforters often use lighter fabrics that perform better in the summer.

Picking the Best Cooling Comforter for You

Though all cooling comforters share the same basic function, specific attributes of individual models can vary widely. While the climate where you live and your sleeping needs and preferences will determine which comforter is best for you, we suggest taking the following considerations into account when shopping for a cooling comforter.

SizeSize options vary according to the manufacturer, but most comforters are designed based on standard mattress sizes. Some comforters are slightly oversized for extra drape or use on higher-profile mattresses. Some manufacturers offer the same size comforter for full and queen mattresses.
WeightCooling comforters tend to be lightweight, as heavier comforters have a tendency to trap heat.
Temperature RegulationSome cooling comforters specifically benefit hot sleepers, while others have more advanced temperature regulation that makes them suitable for different types of sleepers and year-round use.
DurabilityDurability depends on the quality of materials and construction. In general, natural fills like down or cotton are more durable than synthetic alternatives.
CostThe cost of a cooling comforter varies widely depending on the brand, materials, and construction. While prices span from less than $100 to more than $500, you should be able to find a quality cooling comforter in the range of $200 to $300.

Can Cooling Comforters Help With Night Sweats?

Cooling comforters may help relieve night sweats by regulating body temperature and preventing overheating. However, night sweats have many causes, some of which may not be alleviated by a cooling comforter. People with severe or persistent night sweats should consult their doctor.

What Else Can You Do to Keep Cool at Night?

While a cooling comforter can be an effective way to reduce hot sleeping, there are a number of other steps you can take to stay cool at night. 

  • Try a Mattress With Better Temperature Regulation: If you’ve tried other bed-cooling strategies without success, it may be time to consider a cooling mattress. In general,  hybrid and latex mattresses are naturally more breathable and resistant to heat buildup than all-foam mattresses. That said, some foam mattresses contain cooling agents to counterbalance the material’s tendency to trap heat. 
  • Use Pillows and Bedding Made of Breathable Fabrics: If you’re a hot sleeper, you may benefit from using cooling sheets and cooling pillows constructed from breathable materials. Fabrics made from materials like cotton and bamboo-derived viscose allow for extra airflow that may help dissipate body heat.
  • Keep Your Room Cool: Taking a few steps to cool your room can make a big impact on your sleeping temperature. Air conditioning, fans, or an open window can help regulate room temperature overnight. Keeping blinds closed during the day prevents heat from building up in the room.
