I’ll go over our top picks for the best cooling sheets. I will also share key details to pay attention to when sheet shopping, how to determine if you need cooling sheets, and how to care for them after purchase. This review has been updated with our most recent testing and sheet picks.
Depending on your body weight, the climate you live in, and whether or not you sleep with a partner, staying cool throughout the night can be a challenge. Of course, no one enjoys waking up to a moist bed and realizing they broke a sweat throughout the night, but the ability to stay cool can also be an indicator of your sleep quality.
According to sleep experts, your body temperature should decrease to initiate sleep, and things like your bedroom temperature, pajamas, and bedsheets can help facilitate that process. Whether you’re interested in cooling sheets for personal preference or for your health, we’ve rounded up the best sheets to keep you cooler than a cucumber.
Our expert product testers chose the Sleep Number True Temp Sheets as the Nerd’s Pick for the best cooling sheets due to their incredible quality, breathability, and cooling technology.
Join Becca in the Nerd lab as she gives you a run down of our top cooling sheet picks.
To assemble our list of the best cooling sheets, our team of mattress and bedding experts tested and evaluated about 30 different sheet sets, looking at factors such as temperature regulation, quality of materials, comfort, and more. Check out the individual reviews to learn more about the testing process and how each sheet set performed.
The True Temp sheets are made from a 300-thread-count blend of cotton, polyester, and spandex—though cotton is the main material. This fabric mix creates a smooth, yet crisp and breathable, material, which supports Sleep Number’s proprietary cooling technology. The 37.5 technology works to adapt to your body’s temperature and humidity level to maintain a balance—not too hot and not too cold.
Before you get too excited, it’s important to point out that these Sleep Number sheets only come in Queen, King (Standard, Split, and FlexTop), and California King (Standard, Split, and FlexTop). Unfortunately if you have a smaller bed, these sheets won’t be available to you. It’s a bummer, we know.
The Nerd’s Pick in our best cooling sheets roundup are the sheets that sleep the coolest. In our testing, the True Temp sheets earned a perfect score in temperature regulation. That result, plus the high quality of its construction, earned it the top spot in our list. We think you’ll love the Sleep Number sheets, but make sure to peruse the rest of our picks to ensure the True Temp sheets are right for you.

Out of 10,000 reviews on Sleep Number’s website, the True Temp sheets earned 4.6 out of 5 stars.

The Cozy Earth bamboo sheets are the softest sheets I’ve ever felt. They’re made entirely from organic and hypoallergenic bamboo viscose, which gives the sheets their silky, airy, and luxurious feel
The Cozy Earth sheets are incredibly buttery and silky smooth. They’re made from 100 percent bamboo viscose with a sateen weave—a match made in heaven for bedding. Bamboo is a great material for regulating body temperature, wicking moisture, and keeping cool. Plus, they’re hypoallergenic.
When you lie down, the Cozy Earth sheets drape over you while still feeling breathable and airy. The fitted sheet also has deep pockets, which is ideal for tall mattresses or beds stacked with a thick mattress topper.

The Cozy Earth Bamboo sheets have an average rating of 4.9 out of 5 stars based on over 5,000 reviews. Most negative reviews complain of pilling after a few washes, but reviews are overall positive, praising the quality, softness, and breathability of the sheets.

The Parachute Percale sheets are for crisp-bedding lovers who need to stay sweat-free throughout the night. We love that they’re made with 100 percent long-staple Egyptian cotton: The Egyptian cotton gives them a smooth feel, but the percale weave maintains breathability. As for sizing and color options, you get to pick from every standard size (Twin to California King), and seven different neutral colors.
What our testers say: “In terms of staying cool as you sleep, I found the Parachute Percale sheets to be cool to the touch and lightweight. I equate the feel to a freshly laundered, button-down dress shirt.” – Becca, Lead Bedding Tester
Parachute’s website shows 4,403 reviews with an average rating of 4.4 out of 5 stars. Negative reviews call out the lack of softness and the colors not matching the advertised picture. The positive reviews enjoy how cool these sheets sleep and how high the quality is.

The Saatva Organic Sateen sheets are luxurious, 300 thread count sateen weave sheets. Their silky and buttery feel, and lightweight feel make them perfect for shoppers looking to splurge a bit on quality sheets.
Sateen sheets are known for being silky soft and a bit thicker than percale sheets, but the Saatva Organic Sateen sheet set still manages to work wonderfully for hot sleepers. Saatva is luxurious, cool to the touch, and high quality thanks to the 100 percent long-staple cotton fabric and 300 thread-count sateen weave.
After their first wash, you should notice the softness increase without sacrificing breathability. Usually, the higher the thread count, the warmer the sheets sleep, so you want to aim for sheets that fall between 200-400 thread count, and Saatva hits that sweet spot right in the middle.
What our testers say: “Personally, I think the sateen weave is the key to unlocking why the Saatva Sateen sheets are so soft and comfortable. It gives the sheets a silky sheen, and they feel buttery smooth when I lie under them.” – Becca, Lead Bedding Tester
On the Saatva website, the Sateen Sheets have 4.7 out of 5 stars. Reviewers think the sheets are soft, cooling, and comfortable, but some negative reviews criticize the high price and limited color choices.

These luxurious sheets from LUXOME are made from 100% pure viscose bamboo with a 400 thread count, which means they're silky soft, breathable, and durable.
Best value doesn’t mean that these sheets are cheap, it means they give you a ton of bang for your buck. The Luxome sheets are made from bamboo viscose and naturally wick moisture and regulate temperature. They also have a silky, shiny finish that both looks and feels like luxury. A Queen set can be yours for around $150, a price that we think is more than fair for this high-quality product.
What our testers say: “Bamboo sheets are my personal favorite, and the Luxome set holds its own against the big boys. They’re soft to the touch and feel silky smooth against the skin.” – Loren, Editor & Bedding Tester
On Amazon, the Luxome sheets have 4.5 out of 5 stars. Negative reviews complain the sheets start to show signs of wear and tear after a few washes. Positive reviews praise the soft, temperature-regulating feel.

The Layla Bamboo sheets are made from 100 percent bamboo viscose with a 300 thread count for a silky smooth feel and sheer finish. If you’re into the texture of silk, we think you’ll love these sheets.
These sheets don’t retain much heat, which is exactly what landed them on this list. The 300-thread-count, bamboo-viscose construction makes these sheets lightweight and hypoallergenic. They’re only available in white or gray, but what they lack in color options they make up for in stylishness—the sheer finish will look fantastic in just about any bedroom.
What our testers say: “If you’re like me and you have any allergies or sensitivities, the Layla Bamboo sheets get my hypoallergenic stamp of approval. I experienced no adverse allergic reaction when I tested these out for myself.” – Becca, Lead Bedding Tester.
The Layla Bamboo sheets received 4.5 out of 5 stars from reviews on their website. Negative reviews called out the smaller pockets and said that they sleep too cold to be good for winter. Positive reviews highlighted the comfort and cooling capabilities.

The ideal cooling sheet set will allow your body to settle into a temperature that’s comfortable for sleep and remain that way throughout the night. They’re a must-have during the hot, muggy months of summer or if you live in a place that’s warm year-round. We also recommend them if you tend to sleep hot regardless of the season, which can be an issue for tall or overweight individuals, and those with a partner who sleeps hot.
This buyer’s guide will tell you everything you need to know about cooling sheets, so you pick the best set for you. And, if you want to make a big change to keep yourself cooling, consider checking out our list of the best mattresses for hot sleepers.
Not all fabrics are created equal when it comes to their ability to help you reach the ideal sleeping temperature, which is roughly 65 degrees. Hot sleepers need extra-breathable materials like cotton, linen, bamboo, silk, microfiber, and tencel, which, when not blended with other materials, sleep much cooler than other fabrics.
Egyptian is the most popular cotton choice, but it is also the most expensive. Linen comes in even cooler than Egyptian cotton and can be found at a wide variety of prices. Fabrics like microfiber, Tencel, and bamboo can be even more affordable.
Thread count is most often associated with softness, with higher thread counts indicating a softer feel. This number can also indicate a sheet’s cooling properties. Higher thread count sheets have more threads per square inch, which may leave you warm and sweaty. A thread count of 200 to 400 is a nice range to aim for when looking for cooling sheets, but the ideal number will vary depending on the fabric you choose.

“Organic” and “natural” are becoming common terms in the bedding industry as manufacturers warm up to consumers who are environmentally conscious. Natural and organic products (like cotton and bamboo) can hike up prices a fair amount, so you’ll want to check the label for certifications regarding these claims.
The term weave refers to how the fabric is stitched together. The weave affects the breathability of the fabric as well as its texture, two qualities that, in turn, impact how much moisture the end product will retain and how it will feel to the touch. Here are the weaves that are best for cooling, breathable sheets.
When shopping for the best cooling sheets for your bed, you’ll likely notice the variety of styles, colors, patterns, sizes, and materials available. While each sheet set will come with its own unique instructions for care, most cooling sheet sets are machine washable. To play it safe, we recommend washing sheets on a cool setting and drying on a low heat or air dry setting. Some manufacturers may recommend hang-drying sheets.
Pay careful attention to labels when treating stains. Some sheets may take bleach well, but it could ruin others. When in doubt, use the least chemically aggressive method possible. Most bedding companies also have cleaning details on their websites, if the tag on the product doesn’t provide clear instructions or warnings.
Cooling sheets have increased greatly in popularity over the last few years, but here’s a list of individuals they may be appropriate for to help you evaluate whether cooling sheets would be a good fit for you.
Whether you have night sweats year-round, occasionally sleep hot on a particularly warm evening, or anticipate hosting guests who you suspect to be hot sleepers, owning at least one set of sheets with proven cooling properties is a good idea.
We already mentioned the best cooling mattresses, but there are plenty of other options for those who tend to get uncomfortably hot at night. You could try a cooling pillow or a cooling pillowcase, which are two relatively affordable options.
If you’re in the market for a new blanket, consider a cooling weighted blanket or a cooling comforter. Or, if you want a more substantial change but don’t feel like buying a whole new mattress, check out our list of the best cooling mattress toppers. Remember, your thermostat may not be the only problem when it comes to overheating at night. A simple change to your mattress and its accessories can make a world of difference.

The best cooling sheets have a thread count between 200–400, a loose weave, and breathable materials. All of our picks check that box, but we highly recommend cotton or bamboo sheets for moisture-wicking comfort. Good luck on your sheet-buying journey!
The coolest types of sheets are made of cotton, Tencel, or bamboo. These sheets should have a looser weave, so air flows through the fabric and your body heat doesn’t get trapped. When it comes to thread count, anything that falls in the 200–400 range should be good for hot sleepers.
Cooling sheets do work when compared to warmer sheets like fleece and flannel. Be aware that sheets are not the only thing to consider when you sleep hot. Your mattress should have cooling infusions and breathability, and so should your pillow, mattress topper, and any other bedding accessories. Make sure to keep your bedroom between 65–67 degrees to help you stay cool.
Percale sheets are the type that feel crisp and smooth. Percale is a weave typically used with cotton fabric. The higher the quality of the cotton, the smoother your sheets will be. The percale weave gives the cotton that crisp, cool feel you’re used to from hotels.
There are a couple of tips and tricks to keeping your bed sheets cool: The first is putting them in the freezer before bedtime. You can also try keeping the fan on in your room all night to keep air flowing. You can also use a cooling mattress topper, like the Eight Sleep, to keep your sheets cool all night.
