The Sealy Cooling Moisture Wicking Waterproof Crib Mattress Pad features a premium soft knit top with a moisture wicking finish that helps keep baby cool as moisture is wicked away from baby’s body for a cool, dry, and comfy sleeping surface. A waterproof barrier protects crib and toddler bed mattress from moisture and makes clean-ups a breeze. The crib pad is PVC-free and the quilted filling, made from recycled bottles, offers extra coziness for your little one. A premium SecureStay fitted stretch skirt wraps under baby's mattress form a snug, secure fit. We recommend that new parents purchase 2-4 crib mattress pads, so you always have a fresh, dry pad on-hand while the others are in the wash.
