We tested the Sleep Number True Temp Blanket and vetted five other cooling comforters. See our top pick for each interest.

Like “old news” or “unbiased opinion,” a cooling comforter might sound like something of an oxymoron. Comforters can help keep you warm while you sleep, so you may throw one onto your bed as soon as the weather starts to cool.

But what if, like many people, you heat up in your sleep? Some medications, certain health conditions, and even a natural tendency to sleep hot can cause your body temperature to rise overnight, leaving you tossing and turning or breaking into night sweats.

Investing in a top-value cooling comforter could make a difference in your sleep. These comforters help regulate your body temperature or draw away moisture from your body as you sleep. Find our top picks below.

A good, all-season cooling comforter will have most, if not all of the following features:

  • lighter weight
  • breathable construction
  • body temperature regulation and moisture-wicking abilities

We considered these features along with the following important criteria:

  • Price: You’ll use a good comforter every night for years to come, so it’s often worth investing in the right one. That said, some cooling comforters can cost a few hundred dollars. Not everyone wants to spend that much, so we made an effort to include cooling comforters at a variety of price points.
  • Customer reviews: We read hundreds of customer reviews to make sure we selected comforters that really do help keep you cool and feel soft and cozy at the same time.
  • Materials: When it comes to comfortable sleep, the materials in your bedding matter. We looked for the softest cooling comforters made of natural, breathable, and moisture-wicking fabrics. What’s more, all the comforters we selected are filled with vegan-friendly natural or down-alternative fibers.

Best overall cooling comforter

Slumber Cloud Lightweight Comforter

  • Price: $$$
  • Material: polyester fill and 100% cotton cover
  • Sleep trial: 60 nights
  • Machine washable: yes

If you dreamed about traveling to space as a child but have since remained firmly grounded on Earth, it may be a small comfort to know you can still sleep under space technology.

That’s right, Slumber Cloud says this comforter features the same temperature regulation technology used in NASA spacesuits.

People tend to sweat at night when humidity builds up between the mattress and their comforter or other bedding. The unique fibers in this Slumber Cloud lightweight comforter, however, are designed to help absorb and release the heat you generate during sleep.

The company says tiny beads of the polyester fill trap heat as your body temperature rises, holding onto this heat and keeping it away from your body until you cool down again. Then, the beads release the heat to warm you back up.

This cycle helps reduce humidity in your bed, so you can sleep more comfortably.

It has more than 1,700 5-star reviews, making it one of today’s best-rated cooling comforters on the market.

This comforter comes in two weights, and if you live in a colder climate, you may want to opt for the slightly heavier comforter.


  • The vast majority of reviewers love this comforter.
  • People love how light and soft it feels, and they say it makes a huge difference in their sleep.
  • Many reviewers say they no longer wake up sweating or spend the night wrestling with their bedding in an effort to cool down.


  • A small handful of reviewers say this comforter didn’t resolve their overheating or sweating.
  • A few people note the lightweight version is a little too light.

Best budget cooling comforter

Ebern Designs Trinway Comforter

  • Price: $
  • Material: polyester fill and microfiber cover
  • Sleep trial: no
  • Machine washable: yes

The cooling fibers in this reversible comforter are designed to help keep you from overheating as you sleep. If you do happen to sweat a little (which is totally normal), the moisture-wicking cover can help you stay cool and dry all the same.

This comforter features a unique U-shaped design that helps prevent the fibers filling the comforter from lumping and bunching up in one place. The extra fill along the comforter’s edges is supposed to help it stay properly on your bed instead of slipping away.

While this comforter may not be the coolest option on the market, it’s one of the best deals available and may work well if you’re looking to beat nighttime heat at a bargain price.


  • Reviewers call this one of the most comfortable, softest cooling comforters, saying it has a nice weight for both winter and summer.
  • Many warm sleepers say they notice improvement after sleeping under this comforter.
  • People say it helps reduce night sweating for cooler, more comfortable sleep.


  • A few people say they still wake up overly warm, though.

Best cooling duvet

Purple TempBalance Duvet

  • Price: $$
  • Material: polyester fill and cotton cover
  • Sleep trial: 30 nights
  • Machine washable: no

Comforters and duvets are fairly similar. Duvets generally contain a fill of natural or alternative down that’s loosely packed for a fluffier look and feel. While duvets with heavier fill make great bedding options for colder climates, hot sleepers may sleep better under a more lightweight duvet.

This down-alternative option from Purple, the company known for the Purple Mattress, comes in two weights. Reviewers say the lightweight option is the best duvet for hot sleepers.

The company says the polyester fill is hypoallergenic and cruelty-free. It’s also sewn down to help prevent bunching. Breathable cotton helps keep the cover cool and comfortable, and duvet loops help secure this insert inside a duvet cover of your choice.

This duvet may also work well for couples who sleep at different temperatures. A few reviewers say this duvet crinkles slightly due to the fill, but most people don’t seem bothered.

While some reviewers mention putting this duvet through the wash, keep in mind that it’s labeled as dry clean only. Machine washing the duvet may void the 30-night sleep trial.


  • One reviewer called this the best duvet insert they have, saying it keeps them cool and their husband “toasty warm.”
  • Reviewers praise this cooling duvet insert, saying it keeps them warm in the winter and helps them stay cool in the summer.
  • People say it has the “perfect” temperature and feels comfortable to sleep under.


  • One reviewer notes that it didn’t keep them cool enough but did add that it stayed cooler than a typical comforter.

Best organic cooling comforter

Ettitude Bamboo Comforter

  • Price: $$$$
  • Material: organic bamboo lyocell
  • Sleep trial: none
  • Machine washable: no

This organic comforter is made entirely from sustainable bamboo. Like other natural fibers, bamboo has breathability that makes it one of the best lightweight comforters for summer and a good option for cooler, comfortable sleep.

Ettitude uses bamboo pulp to create lyocell, smooth, durable fabric with moisture-wicking cooling technology for better sleep. The result is a silky cooling comforter that offers the feel of a down comforter in a hypoallergenic, vegan package.

As a bonus, the company says its nontoxic fiber creation process saves 98% of the water used.

While this comforter comes in a winter weight, reviews recommend the lightweight version for summer or winter, saying it warms just as well as it cools.

Note that the company does not offer a sleep trial for comforters, but you can try their sheets, duvet covers, and pillowcases risk-free for 30 nights.


  • Most reviewers love this comforter.
  • Even people who describe themselves as very warm sleepers say it works well to help keep them cool and comfortable at night.
  • People love the weight and satiny feel of the comforter.


  • The attached duvet loops help it stay in place inside your duvet cover, but a few reviewers wish it had some additional loops to keep it more secure.
  • A few people note it can get a little slippery when you pair it with sheets of the same fabric.
  • A few say reviewers it was a little thin for the price.

Best temperature-regulating cooling comforter

The Buffy Breeze

  • Price: $$$
  • Material: eucalyptus
  • Sleep trial: 7 nights
  • Machine washable: no

This cooling comforter is made entirely from eucalyptus grown in renewable forests, making it a great option for greener sleep. The breathable eucalyptus fiber fill is designed to help regulate your temperature as you sleep by releasing body heat instead of trapping it in.

The eucalyptus lyocell fabric used to make the cover is supposed to feel super soft and smooth and stay cool as you sleep. Stitching across the cover helps keep the fill in place, while loops at the comforter corners help keep it secure inside a duvet cover.

The Buffy Breeze comforter is designed for hot sleepers, especially those who live in warmer climates, but it may also work well for people with allergies since eucalyptus fibers naturally resist mold and dust mites.

Note that this isn’t an overly fluffy comforter, but its thinner profile makes it a good option for people who sleep warm.


  • Most reviewers found a lot to love about the Buffy Breeze comforter.
  • Hot sleepers who don’t get relief with other cooling comforters say it helps them get much better sleep without sweating or tossing and turning.
  • Reviewers rave about the soft feel and comfortable weight of the eucalyptus fill and fabric.
  • A few reviews confirm that the Buffy Breeze comforter stays cool to the touch.


  • A few people find the price tag a little high.

Best total set

Sleep Number True Temp Blanket

  • Price: $$
  • Material: polyester/37.5 polyester technology fill and cotton/37.5 polyester technology cover
  • Sleep trial: 100 nights
  • Machine washable: yes

Designed to adapt to and regulate your body’s temperature throughout the night, the Sleep Number True Temp Blanket is a high quality comforter for hot sleepers and one of the best moisture-wicking options on the market.

It features 37.5 technology, which uses particles from natural volcanic minerals with billions of micropores. This can attract and capture moisture to block the buildup of heat and humidity, helping you keep cool while you sleep.

It also includes a breathable cotton cover in several colors and is hypoallergenic for sensitive skin. Plus, a 100-night guarantee backs it, so you have plenty of time to ensure it’s a good fit.

Though you can buy this lightweight comforter on its own, it’s designed to be used alongside other products in the company’s True Temp line, which includes a:

Optional extras are also available to upgrade your sleep experience even more, including:

While purchasing the entire set can be quite an investment, the line is popular among online reviewers, who note that it’s one of the best all-season bedding sets on the market for hot sleepers.

What our tester says

“My husband and I both toss and turn as side sleepers and are prone to overheating and night sweats. We felt relieved and comfortable with Sleep Number’s True Temp Comforter.

“If you have a heavier comforter still on your bed, you may want to swap it out for the True Temp Blanket — it’s delightfully refreshing to sleep in Sleep Number’s 37.5 True Temp technology, with no night sweats and not need to roll away from a sleep partner as often due to compounding body heat.

“I would also recommend the sheets and pillow if your main goal is to sleep cool.

“The sheets aren’t smooth like a high thread count or sateen, but the coolness and redistribution of heat is refreshing. Plus, the pillow follows through on its claim to adapt to your body temp through the night and keep you from sweating on your head or neck.”

Kristin Currin-Sheehan, Healthline Multimedia Editor


  • Some say it’s fluffier than some other cooling comforters.
  • Many appreciated the five color options.
  • It still keeps sleepers warm on cooler nights.


  • A couple of reviewers report the blanket starts pilling after the first few weeks or washes.
  • A few reviewers note the width is not standard, and if you get a comforter that matches your mattress size, you may find it too shallow, especially after laundering.

Best cooling weighted blanket

Luxome Cooling Weighted Blanket

  • Price: $$
  • Material: organic bamboo lyocell, glass beads, and minky (optional)
  • Sleep trial: no
  • Machine washable: yes

Skeptical of a weighted blanket that also keeps you cool? It does sound a little unlikely, but this cooling bamboo blanket seems to do the trick for many sleepers.

The company uses tiny glass beads between the blanket layers to provide a comfortable weight that may help you fall asleep faster and sleep more soundly. The organic bamboo lyocell fabric helps draw away moisture from your body to keep you cool and comfortable and prevent excess sweating.

This blanket comes in a few different styles. You can choose between a comforter-style blanket with a removable bamboo cover and a reversible comforter-style blanket with bamboo on one side and minky fabric (a super soft version of fleece) on the other.

The bamboo fabric is designed to stay cool as you sleep, so warm sleepers may want to stick with one of the bamboo-only blankets for optimal cooling. The reversible minky blanket won’t offer the same breathability, though.

People also love the quality construction and soft texture of the fabric. Many recommend Luxome for their customer service and superior products.

Though the company doesn’t offer a sleep trial, you have 30 days to return items in like-new condition.


  • Reviewers love this blanket, noting it stays much cooler than other weighted blankets.
  • Several people say they noticed relief from night sweats and improved sleep right away.
  • Even reviewers who find the blanket a little too heavy still praise the temperature regulation.


  • Reviews from people who sleep on the warmer side confirm that, while the minky fabric feels soft and cozy, it doesn’t do much to cool them.

When searching for the best cooling bedding, you’ll encounter plenty of options. The quick tips below can help you choose the right comforter for your needs.

What is the best material for a comforter to keep you cool?

Generally speaking, natural fibers will keep you cooler than synthetic or man-made fibers. While some cooling comforters have a synthetic polyester fill, you’ll find that most highly rated cooling comforters have covers made of a natural fabric.

Some budget cooling comforters may have synthetic covers specially treated to wick moisture and keep you cooler, and these can be good options, too. Just read the reviews first to make sure they really do stay cool.

Fabrics to look for:

  • Cotton: This material is breathable and affordable. Many cooling comforters feature a cotton cover.
  • Linen: This fabric is highly breathable and has excellent moisture-wicking properties. There’s a reason why so many summer clothes are made of it.
  • Wool: This option might inspire thoughts of chilly days, but its strong moisture-wicking abilities make it a great option for filling a cooling comforter. Wool bedding and sleepwear can help draw away heat and moisture from your body and help you maintain a comfortable temperature.
  • Bamboo: This material makes a smooth fabric that often feels cool to the touch. Some people don’t love its slippery feel, but it can help regulate body temperature and ensure breathability and comfort through the night.
  • Eucalyptus: Fibers from eucalyptus can also be woven into cooling fabrics that help regulate body temperature.
  • Silk: This bedding may cost quite a bit, but some people find it well worth the price for its improved breathability and temperature regulation. However, while silk can help keep you cool, it may not respond well to sweat.

Comforters with natural fiber fill may also do more to keep you cool than comforters with down or polyester fill.

What size comforter should you get?

If you sleep on a queen bed, you’ll want a queen-size comforter, right? Well, maybe not. People looking to purchase a new comforter often choose one in the same size as their bed, but this may not always be the best option.

If you share your bed with a partner, you might want a bigger comforter to end the nightly battle for blankets that leave one of you with cold feet. A larger comforter size may also work better for restless sleepers. You might even prefer the look of a larger comforter hanging over your bed’s edges.

Duvets tend to be a little smaller than comforters, so you’ll want to make sure to check the size before you purchase.

On the other hand, you might not want a large comforter size, especially if you sleep hot. Going down a size could leave you with just the right level of lightweight comfort.

Two smaller comforters can also offer a good solution for partners who sleep comfortably at different temperatures.

Comforter and duvet sizing can vary by brand, though most brands offer product specifications and may recommend sizing up if you prefer a little overhang.

What’s a reasonable price?

When it comes to comforters and bedding in general, a slightly higher price will usually (but not always) get you a better quality comforter.

More affordable options sometimes leave little to be desired in construction and fabric quality.

You’re also more likely to find eco-friendly, organic, and sustainably produced bedding at higher price points.

You can expect to pay anywhere between $100–$250 for a top-value cooling comforter that will last several years.

Of course, it’s not impossible to find a decent comforter for a lower price. But when you want a comforter that really keeps you cool, saving up for a superior comforter may offer a better long-term solution than simply searching for the best deals or running through a succession of inferior options that leave you sweating.

What else should you look for?

A few final considerations:

  • Check the care instructions before making your purchase. If you hate spending money on dry cleaning, you won’t want to end up with a comforter you can’t wash.
  • If you plan on protecting your comforter or duvet with a machine-washable cover, you may want to consider a comforter that comes with attached loops for security.
  • Picky about your bedding? Not sure you want to spend a few hundred dollars on something that may not actually work for you? You can look for a retailer that offers a sleep trial. This way, you can try your new comforter before making up your mind.
  • If buying green matters to you, you might look for a company that’s up front about their manufacturing process. Do they use renewable bamboo and eucalyptus? How do they reduce waste when making their products? Do they prioritize fair wages and good working conditions?

Many people change their bedding by season: lightweight sheets and a thin blanket in the summer, and heavier sheets and thicker blankets in the winter.

There’s no need to change a method that works well for you. But switching to a lighter temperature-regulating comforter could help you stay more comfortable year-round and make your life easier at the same time.

If you live in an area that gets very warm in summer and very cold in winter, you probably need to keep some extra bedding on hand. But a cooling comforter can make a big difference on those sticky summer nights.

You may want to switch to a temperature-regulating comforter if you regularly find yourself:

  • waking up sweaty or overheated
  • tossing and turning because you feel too warm
  • having difficulty falling asleep on warmer nights

Updating your mattress, mattress topper, sheets, or pillows to cooler options can also make a big difference. We recommend starting with cheaper options first before springing for a new cooling mattress.

What kind of comforter is the coolest?

Look for a cooling comforter made from lightweight, breathable materials, such as cotton, bamboo, or eucalyptus. For all-season cooling, also opt for a comforter with moisture-wicking cooling technology or other built-in features to help regulate your body temperature.

Do cooling comforters actually work?

A temperature-regulating comforter can definitely make a difference if you’re a hot sleeper or tend to wake up covered in sweat. Most cooling comforters work by trapping and releasing heat and moisture to help you sleep better throughout the night.

Other bedding upgrades — such as a cooling mattress, sheets, or pillows — can also be a game-changer for all-season cooling.

What type of comforter is best for hot sleepers?

The Slumber Cloud Lightweight Comforter is among the best lightweight comforters for hot sleepers, thanks to its moisture-wicking cooling design, which traps heat to help regulate your temperature while you sleep.

It can also release the heat that your body generates to warm you up when it’s cold, making it one of the best all-season options on the market.

The Buffy Breeze comforter is another solid, eco-friendly option, which is made entirely from eucalyptus for added breathability and a soft and smooth feel.

The temperature of your bedroom and bedding can play an important part in your sleep. Overheating at night can leave you sweaty and uncomfortable, preventing you from getting quality rest.

Over time, disrupted sleep can affect your:

  • physical health
  • mood
  • daily wellness

If you’re tired of waking up in a damp, sweaty bed, try a cooling comforter for a sounder, breezier sleep.
