Five Sided™ + Omniphase™ Mattress Protector

Advanced cooling protection for a cleaner, more comfortable night’s sleep. The Five Sided™ + OmniPhase™ Mattress Protector is built for sleepers who want more than just basic mattress protection. This premium protector combines three advanced technologies—TENCEL™ Lyocell fibers, OmniPhase® temperature regulation, and the H2Pro® waterproof membrane—to keep your bed cool, dry, and protected night after night. OmniPhase® phase-change technology actively absorbs and releases heat to help maintain a comfortable sleep temperature in any climate. The TENCEL™ Lyocell fabric naturally wicks moisture away from your body, helping you stay cool and dry while you sleep. Beneath it all, the laboratory-certified H2Pro® membrane creates a quiet, breathable barrier that blocks liquids, dust mites, and allergens without trapping heat. Designed with a fitted-sheet style and Universal Fit™ elastic, this protector securely fits mattresses from 6" to 22" deep, protecting the top and sides of your mattress while maintaining a smooth, comfortable feel.
