The Sealy Allergy Protection Plus Crib Mattress Pad has a double layer of protection with a micro-weave top layer and a 100% waterproof membrane to help protect baby's mattress. A plush layer of quilted filling provides added comfort and softness for baby, while the SecureStay fitted skirt wraps underneath the crib mattress for a snug fit. This crib mattress protector pad is machine washable and dryer friendly for quick and easy cleaning. 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.
