The DMI Waterproof Mattress Protector in Twin size helps you protect your mattress investment with full encasement coverage. A zippered closure encloses the mattress on all sides to help block liquids, dust, and allergens from reaching the surface. The waterproof layer is designed to stand up to bedwetting, incontinence, and spills, making it especially useful in kids' rooms or multi-use spaces. The protector fits snugly and quietly, so it won't shift or create distracting noise while you sleep. When needed, it can be removed and machine washed to keep your bedding feeling fresh. This twin encasement is a smart addition for homes with children, pets, or frequent guests.
