Finding ideal bedding can be tricky if you’re a hot sleeper. On one hand, having a nice blanket or comforter can be cozy and inviting. On the other hand, if you already tend to sleep hot, having a comforter can cause you to sweat and overheat in the night. Thankfully, there are comforters that allow you to get some additional warmth and coziness without feeling like you’re spending the night in a sauna.
In this guide, we’ll share our top picks for the best cool comforters in several categories. Our comforter buying guide will also key you into the most important terminology and background information that you need to make an informed decision about the best purchase for you as a hot sleeper.
Our Editor’s Pick is the Buffy Comforter, which uses innovative materials and construction to deliver exceptional temperature neutrality and cool, comfortable sleep. The comforter’s shell is made from fabric derived from eucalyptus fibers, resulting in a naturally breathable and soft material that regulates the sleeper’s temperature well. The Buffy Comforter is eco-friendly, as well, as the fill is derived from recycled plastics. The rough equivalent of 50 plastic bottles are used in one Buffy Comforter.
The comforter offers a lofty feel that also feels light, and good air circulation throughout the interior helps maintain consistently comfortable temperatures. The silky-soft texture can also be beneficial for those with sensitive skin, while the hypoallergenic materials are resistant to dust mites and other allergens. The Buffy Comforter is available in three sizes – Twin/Twin XL, Full/Queen, and King/California King – and the company backs the comforter with a free sleep trial. Free shipping and returns are also available.
Down alternative is the trade name for polyester microfibers that mimic the lightness and softness of authentic waterfowl down. Down alternative is also a popular comforter material because it has a lower average price-point compared to real down, and it also sleeps fairly cool.
Our Runner-Up Pick, the Down Alternative Duvet Insert from Tuft & Needle, accommodates a wide range of sleepers with light and medium weight options. The lightweight design is sewn through, resulting in a relatively thin layer that is optimal for those who sleep hot. The mid-weight design is thicker and features baffle-stitching to prevent the microfibers from clumping or shifting.
The duvet is encased in a Cambric cotton shell that is smooth to the touch. The cover is also highly breathable and helps regulate the comforter’s overall temperature. Stability is another strong point with the Down Alternative Duvet Insert. Corner loops prevent the comforter from slipping off in the night, which can lead to sleep disruptions. Tuft & Needle backs the duvet insert with a 100-night sleep trial and a three-year warranty.
Cool comforters can be a sound investment for sleepers with nighttime temperature issues – but many of these products cost at least $120. The Climabalance Down Alternative Comforter is a notable exception.
The comforter is available in five sizes – Twin, Full, Queen, King, and California King – all of which are widely available for less than $110. However, the Climabalance Down Alternative Comforter offers the same soft, lofty feel and temperature-regulating comfort as many competing products with higher price-points.
The comforter is constructed with a patchwork of mesh squares – also known as ‘climate zones’ – that promote strong airflow and allow the comforter to sleep exceptionally cool. As a result, the comforter is suitable for any time of year.
It provides sufficient cooling and moisture-wicking during hotter times of the year, and also acts as a protective insulating layer when the temperatures dip. The comforter can be washed and dried in a machine, making it relatively low-maintenance as well. The Climabalance Down Alternative Comforter is backed by a 30-night sleep trial.
Casper Humidity Fighting Duvet utilizes a lightweight, cool, and cozy construction to provide an excellent luxury experience. Consisting of a 600-fill power down fill, a 100% cotton shell, and an additional layer of merino wool, this duvet scores well across the board. While the cotton shell is already fairly breathable, the wool has moisture-wicking properties that further regulate the temperature. Add in quality, ethically sourced down to make the essential all-season comforter that’s perfect for hot sleepers and lovers of luxury.
The Casper Humidity Fighting Duvet is priced a little higher than average, but given its high-quality construction, the price checks out. Further, the duvet ships free, includes a 100 night sleep trial, and is protected by a 1-year warranty.
Many hot sleepers prefer down comforters because the material is naturally light and airy, and does not absorb much body heat. It is exceptionally soft, as well. Our pick for this product type is the Brooklinen Down Comforter, which is made in Canada and contains white down that is ethically sourced from Hutterite farms.
The comforter is available in a lighter, summer-weight design with 600 fill power down clusters and a breathable cotton-sateen casing. Customers who prefer a little more insulation may also select an all-season design with 700 fill power clusters.
The comforter’s baffle-box quilting provides even fill distribution, which helps minimize clumping. Tie straps at the corners for the duvet cover also prevent uncomfortable sliding during the night. The comforter is available in Twin/Twin XL, Full/Queen, and King/California King sizes. Brooklinen offers a full satisfaction guarantee with free exchanges and replacements and backs its comforters with a lifetime warranty.
Down alternative, a material made from polyester microfibers, mimics the natural softness and airiness of authentic down. It is a popular comforter material because it is relatively inexpensive and, unlike down, won’t trigger any allergies in sleepers. The Snowe Down Alternative Comforter is our pick for this category. The comforter contains fluffy down alternative encased in a smooth, 330 thread count cotton-sateen cover.
The Snowe Down Alternative Comforter comes in heavier all-season and lighter summer-weight designs. Two sizes – Full/Queen and King – are available for both designs. The cotton cover has received the OEKO-TEX certification, indicating no harmful chemicals are used during production, and the entire comforter is machine washable. Snowe offers free shipping, as well as a 90-night sleep trial with full refunds for product returns.
What’s cooler than being cool? Knowing how to find the best comforter to keep you from sleeping hot. This guide walks you through what you need to know to make a great purchase.
While a lot of focus is placed on the inner material in a comforter, the exterior – also known as the shell – cannot be ignored, especially for hot sleepers. The most common materials for comforter shells include:
The fill material in a comforter will have the biggest impact on how much heat a comforter will retain, and as a result, it is a key point of emphasis for hot sleepers. The most important fill materials to be aware of include:
The thread count, used in describing the shell of a comforter, tells you how dense the yarns are within one square inch of fabric. If you’re not well-versed in sewing and textiles, it will suffice to know that higher thread counts normally indicate a shell that will feel smoother and that will hold up better over time. But it’s also important to know that thread counts can be manipulated to seem higher (through what’s known as “double counting” two-ply yarns in the material). For this reason, we advise looking for a thread count of 300-600 since counts higher than this probably are calculated using double counting.
There are various methods that are used to stitch together the various materials within a comforter.
Sleeping cool isn’t just about your comforter. There are a handful of other ways that you can optimize your sleep environment to prevent from overheating at night.
