Peach skin processing makes it very soft, wrinkle-resistant, and less prone to pilling, providing a smooth and comfortable feel. You can sleep comfortably every day and use it all year round. ★【360° Full Protection】: Features a strong elastic band all around for easy on and off. The high-quality elastic rubber has good elasticity, passing thousands of stretch tests, making it durable and long-lasting. Our mattress cover is specially designed to fit all types of mattresses. It fits perfectly on memory foam, latex, or spring mattresses. ★【Recommended】: Great for nursing care and bedwetting, and effectively prevents water and stains from seeping into futons and mattresses.
