Power your sleep with the comfort you deserve with the Tempur-Pedic TEMPUR-Supreme Twin XL Mattress Topper. This 3" thick memory foam mattress topper instantly improves the comfort of any mattress, evenly absorbing the force of your body and its pressure points to reduce tossing and turning so you can wake up feeling refreshed and ready to start the day. Featuring signature pressure-relieving TEMPUR material, the memory foam topper effortlessly adapts to your unique shape, weight, and temperature to offer the same pressure-relieving comfort and support found in our mattresses. It's designed to reduce motion transfer so you can rest undisturbed even when you're sleeping beside your partner, kids, or pets, helping everyone get the blissful night of sleep they deserve. For increased comfort and durability, the supportive mattress topper is protected by an ultra-soft, hypoallergenic cover featuring Safe-Guard Technology, and the cover can be removed and machine washed as needed for easy cleaning. This medium-firm mattress topper fits neatly over twin XL size beds, and the Staytight corner straps keep your topper securely in place by creating a nonslip connection to your mattress.
