Getting a good night's rest is imperative to our overall health, but there are plenty of things that can get in the way of our precious shut-eye.

One very annoying roadblock to rest? Feeling hot and sweaty in bed. In fact, one study even suggests1 that a thermal environment could be one of the most important factors in your sleep quality.

Beyond finding the right room temperature for sleep, taking steps like investing in cooler pajamas, and reconsidering your sheets are all great ways to keep your body temperature down, similar to the way our bodies evolved over time.

On top of all of these shifts, adding the best cooling comforters to your bed setup is a surefire way to stay cool even as temperatures rise (either from the shift to summer or a radiator on full-blast in the middle of winter).

Below, uncover the best cooling comforters that can help keep you chill all night long and finally get the zzz's you need.

A quick look at the best cooling comforters

How to choose the best cooling comforter

Not only will the design of the comforter itself play a role in how much you love it—i.e., you want it to keep you cool—but it's also important to opt for something that you can actually maintain and take care of. Our priority checklist for choosing the best cooling comforters includes:

Materials

While finding a nontoxic or sustainably sourced product isn't always so simple in the sleep space, the cooling comforter category comes stocked with good options. Although these more eco-friendly options often come at a higher price than synthetic blends, they're worth the extra cash when it comes to snoozing safely. After all, you spend more than a third of your life in bed, which means you want to be surrounded by materials you can trust.

Weigh the pros and cons of each material. Along with linen, the best cooling materials tend to be silk; select cottons, like percale and Supima; and tree fibers, such as bamboo, eucalyptus, and pine. When sourcing these materials responsibly, keep an eye out for certifications, like GOTS organic labels or a Tencel yarn with a closed-loop chemical process.

Care

Caring for your comforter is important for extending its lifespan, especially considering how expensive it can be. If you're someone who prefers to throw things in the washing machine over sending them to the dry cleaner, you'll want to read the care instructions carefully before buying and consider machine-friendly materials, like bamboo Tencel.

Sleep trials & returns

If you struggle to get comfortable at night, you'll want to prioritize a brand that offers a generous in-home sleep trial and a solid return or exchange policy. This will help make your life considerably easier if the weight or material of the comforter you choose ends up not working out for your specific needs—especially because quality comforters typically come at a higher price tag.

Consider your company

So, you sleep hot—but what about your bed buddy? If you share your bed with a partner, a lightweight comforter might not be warm enough for them. A few brands offer an "All-Season" option that can be accommodating for sleepers with different temperature preferences. If the company has a decent exchange policy, it might be a good place to start before going straight to the lightweight model.

How we picked the best cooling comforters

  • Cooling materials: We focused on comforters that use cooling materials like bamboo, silk, cotton, and wool. These are likely your best bet for cooler sleep (although a wildcard synthetic blend made the list!).
  • Reviews: We read hundreds of reviews from hot sleepers in particular to ensure these comforters lived up to their cooling claims.
  • Sustainability: At mbg, we love to focus on brands that create products with Mother Earth in mind. All but one of these comforters make significant efforts toward sustainability by using eco-friendly and recycled materials.
  • Price: We provided a range of products to accommodate a variety of budgets without compromising on quality because everyone deserves cooler, comfier sleep.

Bamboo Comforter by Cozy Earth

Best king size

Sizes available

See all specs

Cozy Earth's Bamboo Comforter is an oversized yet lightweight option that's perfect for folks who sleep in a bigger bed. The extra length ensures even those who run hot can keep their toes tucked under the covers throughout the night.

The details

Available in two fill amount options ("standard" or "extra"), the duvet also comes in two breathable material types: bamboo viscose or mulberry silk. Both options come in a reusable duffel bag and are machine washable on gentle (Cozy Earth says to avoid spin cycles and air dry if possible).

Regardless of the material selected, the comforter shouldn't pill or clump with use, but Cozy Earth offers a generous trial period and a 10-year warranty if you have any issues. Plus, the brand is known for having excellent customer service.

Pros & cons

Pros

  • Oversize for king beds
  • Option for bamboo viscose or mulberry silk

Cons

  • Pricey
  • May not fit all duvet covers

What customers say

This comforter has 4.9 out of 5 stars after more than 600 reviews—and it's also backed by Oprah if that's a selling point for you! Reviewers say it's a great breathable option that provides cozy yet cool sleep. One person writes, "The bedding is the most comfortable I've ever had. It comes out of the dryer without wrinkles, is neither too hot nor too cold, and is a generous fit on my king-size bed." On the con side, a few folks warn that because this comforter is oversized it may not fit in all duvet covers.

Alpaca Duvet Insert (Lightweight) by Avocado

Best for summer
Materials
GOTS-organic cotton percale shell, Natural alpaca fibers
Sizes available
Twin, Full, Queen, King, California King
Trial period
100 nights
Shipping
Free
See all specs

Eco-friendly mattress company Avocado is known for its sustainability efforts, and the brand's bedding is no exception. This duvet insert uses natural alpaca fibers for a fluffy yet breathable interior. Similar to wool, alpaca fiber is known for being moisture-wicking and good for regulating temperature.

The details

The shell is 100% GOTS-certified organic cotton percale, and it's available in two different weight options: lightweight, which Avocado says is best for warmer months and climates, and all-season, which is thicker and warmer. Hot sleepers will likely prefer the first option, but both include the same temperature-regulating materials.

Pros & cons

Pros

  • Two weight options
  • Sustainably sourced, organic materials
  • Carbon-neutral company

Cons

  • Not machine washable
  • Pricey

What customers say

This comforter doesn't have a ton of reviews (just over 60), but a majority of folks give it a positive rating. It gets great comments from hot sleepers and people who live in warmer climates. One reviewer writes, "Nice weight, it really does breathe better than cheaper synthetic duvets. While adding warmth without overheating us 'warm sleepers.' Will simply add a blanket for cold weather. Great quality (stitching, etc.) as all items from Avocado."

Breeze Comforter by Buffy

Best for hot sleepers
Materials
Eucalyptus Tencel lyocell shell & fill
Sizes available
Twin, Twin XL, Full, Queen, King, California King
Trial period
7 night trial (100 night returns)
Shipping
Free
See all specs

Beyond making a quality comforter, staying eco-friendly is at the center of everything Buffy does (which definitely pops them near the top of our list).

The details

This lightweight comforter uses sustainably sourced eucalyptus Tencel for both the shell and interior fibers, and the entire thing is compostable! It also uses unique vertical stitching to ensure even fill distribution with loops on every corner to attach to your duvet cover (which Buffy suggests, as this comforter isn't machine washable). We also love that while the brand focuses on sustainability and quality, this comforter is not a total splurge with prices starting under $200. Plus, Buffy offers a discount if you bundle the Breeze Duvet with the Breeze Comforter to make a set (one for winter; and one for summer).

Pros & cons

Pros

  • Breathable, eco-friendly eucalyptus Tencel
  • Sustainably sourced & compostable

Cons

  • No extended warranty
  • Dry clean only

What customers say

The Buffy Breeze has more than 6,500 reviews with just under a 5-star rating. Hot sleepers give it excellent reviews for breathability and softness. One reviewer raves, "Wow! This is what dreams are made of! I run hot and am a sweaty sleeper and this thing solves all this. Instead of blasting the AC, I can keep it as is." A few folks say they wish it was fluffier, but Buffy does have a warmer, cozier option that uses similar materials called the Buffy Cloud.

Casper Humidity Fighting Duvet

Best for night sweats
Materials
Cotton, Merino wool, Ethically-sourced down
Sizes available
Twin, Twin XL, Full, Queen, King, California King
Trial period
30 nights
Shipping
Free
See all specs

Merino wool is known for its moisture-wicking properties, which is exactly why this pick from Casper is called the "Humidity Fighting Duvet." Inside the 100% cotton shell is sustainably sourced down and a thin layer of merino wool. Casper says this helps naturally wick away moisture—great news for night sweaters!

The details

Another great perk is that the design has many horizontal chambers to better distribute the down and wool throughout the comforter, making it similar in design to your favorite puffy jacket. Based on the time of year that you need to use this cooling pick, it comes in two fills: lightweight and a thicker mid-weight option. Better yet, it's machine washable!

Pros & cons

Pros

  • Two weight options
  • Down filling is certified by the Responsible Down Standard

Cons

  • A little noisy
  • Pricey

What customers say

One shopper gushes, "I'm amazed at how light this duvet is yet it keeps me warm without sweating like I did with my old duvet. And did I mention how light it is? I move a lot before I go to sleep and while I'm sleeping. The Casper duvet doesn't make me feel weighed down and restricted like I did with my old cover." The only con we saw in the reviews was that the crispness of this comforter can be kind of noisy—something to consider if you move around a lot at night.

Down Comforter by Brooklinen

Best cooling down comforter
Materials
Cotton sateen shell, Ethically-sourced down cluster fill
Sizes available
Twin, Twin XL, Full, Queen, King, California King
Trial period
365 nights
Shipping
Free
See all specs

Brooklinen's down comforter comes in three different weight options, all of which use the same 100% cotton sateen shell. The lightweight option is—as the name suggests—the lightest and most breathable option of the three and uses recycled down feathers for the fill.

The details

If you end up finding it too lightweight, you can exchange it within 365 nights for the all-season, which has a little more fluff and uses ethically sourced duck feathers. Each model has baffle box quilting to keep the fill evenly distributed and corner loops for tying into your duvet cover.

Just beware that it's not machine-washable. However, the exterior is treated with ultra-fresh antimicrobials to prevent a stench.

Pros & cons

Pros

  • Ethically sourced & recycled down
  • Three warmth options

Cons

  • Not machine washable

What customers say

With over 117,000 reviews and 4.7 out of 5 stars, Brooklinen's Down Comforter is a hit. One reviewer says, "I look forward to getting into bed with this soft-as-a-cloud comforter! I am VERY choosy when it comes to bedding and have tried many brands. I purchased the lightweight comforter. It is perfect for my husband all year round and perfect for me with a blanket on my side for colder nights."

Note that one potential downside of this comforter (and most down comforters) is that it's not machine washable and is best shaken out outdoors or sent to the dry cleaner.

2100 Series Cooling Comforter by COHOME

Best budget
Materials
Brushed polyester shell, Polyester fill
Sizes available
Twin, Twin XL, Full, Queen, King, California King, Oversized Queen
Shipping
Free with Amazon Prime

It goes without saying, but we'll say it anyway: This is a significantly lower-priced comforter compared to the other options on this list. Sure, that raises an eyebrow or two, but this comforter from COHOME is so highly rated on Amazon that we couldn't resist looping it in as the "best budget" pick.

The details

It's made of all synthetic materials, which contributes to the lower price, yet the comforter manages to retain its cool feel. (Of course, synthetic means you're not getting the highest quality or most natural materials.)

The machine-washable comforter also comes in a few different colors, if you're not one for duvet covers. Just note that because this is from a third party (Amazon) you may not have the same warranty or trial period benefits as the other brands on this list. But for the price, that might be just fine.

Pros & cons

Pros

  • Highly rated on Amazon
  • Super budget-friendly

Cons

  • No sustainably sourced materials
  • No trial or warranty periods

What customers say

After more than 13,700 reviews on Amazon, this bestselling comforter still has a 4.7-star rating. Most reviewers say it's surprisingly high quality for the price and that it keeps them comfortable all night. One person says, "This comforter is shockingly lightweight, but also has enough weight to feel good when lying underneath it. It keeps us both warm, but is also breathable and not too warm, and is very soft as well." A few folks warn that this will come vacuum-sealed but that it fluffs up quickly in the dryer.

Frequently asked questions

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

Materials like bamboo viscose, cotton, silk, wool, and alpaca fibers can all provide a more breathable, temperature-regulating comforter than a traditional down or synthetic blend. Consider the weight of your comforter, too—if you tend to sleep hot, a more lightweight design may help keep you more comfortable.

Do cooling comforters work?

Of course, everyone's bodies and sleep preferences are different. But the great news is that your comforter doesn't need a super high-tech design to provide a cooler night's sleep. Picking a lightweight comforter made from cooler materials like bamboo, cotton, merino wool, or silk can help regulate your body temperature and encourage more comfortable sleep.

The takeaway

If you tend to run hot, the materials in your bedroom can make or break your chances of getting a good night's rest.

Luckily, a cooling comforter can help, as well as the right mattress, mattress topper, and even pillow. Hopefully, a few of our recommendations can help you find your perfect polar sleep setup. Stay cool!
