【Fully Waterproof】 The back uses a highly breathable TPU waterproof membrane to enhance water resistance, preventing moisture from sweat or water from reaching the mattress. This is perfect for nursing care, bedwetting, and effectively protects against water penetration and stains on futons and mattresses. It's great for co-sleeping with children or sleeping with pets. The side panels are also waterproof, preventing leakage. Color: Brown Size: Queen I bought it but didn't use it, so it's new.
