Why Do We “Sleep Hot”?
How Casper designed a mattress, sheet set, and pillow that help the body sleep naturally — and cool.
Why does anyone ever wake up hot and sweaty? Sure, you may just be one of those wildly sweaty sleepers who’s destined to constantly get in a tug-of-war match with their partner, but that’s not the whole story.
The reason a lot of people “sleep hot” has to do with design. The body’s core temperature drops by a couple degrees during the night, shedding heat into the surrounding areas, and certain sheets and mattresses trap in the heat and moisture. It’s like a sleep bubble that prevents your body from regulating its temperature like it wants to.
Casper’s award-winning engineering team worked day and night to engineer products that help your body sleep naturally — and cool. To solve for “sleeping hot,” they set up a series of experiments to better understand the mechanics at play and used these insights to design the perfect pillow, sheets, and mattress for hot sleepers (and every other kind). They’re light and airy, soft and comfy, and help keep you at the perfect temperature throughout the night.
The Casper Mattress
Heat retention, a top complaint with memory foam mattresses, was one of the biggest factors they accounted for in the development of the Casper mattress. The top layer of foam features a breathable, open-cell design to increase circulation. Similarly, the memory foam layer beneath leverages airflow to pull heat out of the top layer, leaving you cool and comfortable. Air can pass freely beneath your body, even when the material contours to your curves.
The Casper Sheets
Soft, crisp, and airy, the Casper sheets won’t trap in hot air. They’re a perfect balance of thread quality, weave, and yarn construction. The result is a cool, breathable sleep environment that’s so outrageously comfortable you won’t want to leave it.
The Casper Pillow
The cool side of the Casper pillow … is both sides. Over a billion silky fibers allow air to move freely throughout the pillow. The outer shell also features a breathable percale cotton that keeps air moving all night long.
You can try every Casper product for 100 nights, and they ship directly to your door.
