Does Memory Foam Get Hard When Cold?

In cold weather, many memory foam mattresses become noticeably firmer. Lower temperatures slow the foam’s ability to respond to pressure, which can make it feel stiff and less comfortable until it warms up.

HEST mattresses are designed to perform differently. The foam used in HEST mattresses is engineered to resist cold-weather stiffness and does not freeze or harden in low temperatures. Made in California from premium materials, HEST foam maintains its comfort and support in cold environments, making it a reliable choice for camping, overlanding, van life, and year-round outdoor sleeping.
