My Fitted Mattress Protector acts as a waterproof barrier against accidental spills and bedwetting with its wick away moisture treatment, protecting your mattress from stains. Plus, the elasticized, fitted sheet style makes for easy on and easy off! The breathable, antimicrobial natural cotton terry cloth surface doesn't alter the feel of your mattress while still providing stain protection. Not only does it prevent dust mites from entering your mattress, but it's also easy to use and easy to clean.
