The Sleep Zone Cool Zone is a stretch-knit sheet set made from nylon and spandex, built for hot sleepers. It has a third-party tested Q-Max of 0.481, so it feels cool on contact, and the deep-pocket fitted sheet fits mattresses up to 21 inches. It was recognized in Good Housekeeping's 2026 Bedding Awards for temperature regulation. Compared with cotton and linen sheets, it trades breathability and a crisp feel for a silky, cool-to-the-touch surface that stretches with the mattress.
