This 100% waterproof mattress protector guards against spills and stains, bodily fluids, and allergens. The soft cover has an extra quilted padded top layer that adds comfort while the noiseless waterproof barrier keeps your mattress as new as the day you bought it. Moisture from spills and accidents can cause irreparable damage to a mattress. Not only could it erode the structural integrity of the bed over time, but it could also promote mold and mildew. Waterproof protectors and pads are a simple and affordable way to safeguard your mattress, thereby potentially extending its usable lifespan. While they shield against liquids, many waterproof mattress pads and protectors also provide some degree of protection against allergens and dust mites to promote a cleaner sleep surface. Protectors are usually designed to defend against dirt and moisture without significantly changing the feel of the sleep surface, while pads traditionally add cushioning.
