If you sleep hot, a cooling pillow for hot sleepers is the smallest change you can make to your bed, and the one you feel the very first night. CoolMist Blue arrives as a matched pair, so both sides of the mattress get one. A cooling pillow for hot sleepers, sold two to a box Flipping your pillow at two in the morning only buys you a few minutes. The cold side goes warm again because the cover soaked up the heat your head just put into it. CoolMist is built around that problem. The cover has two faces. The smooth technical face is made to feel cool against your cheek and your ear on warm nights. The brushed face is there for January. You turn this pillow over by season, not by the hour. Under the cover, the fill is medium. Soft enough to settle into, firm enough to keep your head level with your spine instead of folded down toward your chest. What changes in the first two weeks You stop hunting for the cold side (double-faced cover: cooling face and brushed face) Both pillows on the bed finally match (King size, sold as a pack of two in blue) Sweat and hair oil come out in the wash (removable cover, machine washable) Don't all gel pillows warm up the same? A solid slab of gel does. It feels cold for ten minutes, takes on your body heat, and then has nowhere to put it. CoolMist is not a slab. The cooling face is designed to sit cool against the skin, and the fill beneath it is open and breathable, so warmth keeps moving away from your head instead of collecting under it. That is why the fourth hour feels like the first. Free shipping over $149, otherwise a flat $8.90, and your order arrives in 8 to 10 business days. Then sleep on both pillows for 90 nights.
