Yes, cooling sheets work by providing lightweight coverage, wicking away moisture, and often, having a cool-to-the-touch feel. That said, they aren’t the end-all-be-all solution to cooler rest. Other factors, like the temperature in your home, whether you sleep with a partner and even the type of pajamas you wear all play a role in how warm or cool you’ll sleep.

After testing 15 different options, we found the Cool+ Sheet Set from Coop Sleep Goods to be the most effective at regulating temperature. Its blend of breathable materials make it feel lightweight, silky-smooth and breathable.

While the best thread count for cool sheets will largely depend on the material, we recommend opting for a thread count of 400 or lower to ensure maximum breathability. As a general rule of thumb, the higher you go in thread count, the heavier the sheets will feel, which can make them feel warmer and more enveloping. You may be able to get away with a higher thread count on cotton sheets given the natural breathability of the material, although we recommend avoiding anything above 500.
