Designed for a better night's sleep, this soft mattress pad combines a comfortable quilted top with a durable underside of polyurethane for a protective waterproof bed setup. Incorporating smooth 200 thread count cotton surfacing over hypoallergenic polyester fiberfill quilting, the cozy foam mattress pad maintains breathability while improving overall comfort in any season. The durable polyurethane layer is soundless when moved on, so it protects the mattress pad without noise. The pad's flexible knit sides hug mattresses up to 22 inches deep to keep it snug, smooth, and centered. Available in twin, extra-long twin, full, queen, king, and California king, this waterproof mattress pad can be machine washed and tumbled dry for easy maintenance.
