【Five-Sided Waterproof Design & Water-Resistant Performance!】This waterproof sheet uses a laminated, waterproof polyurethane TPU membrane, providing excellent water resistance. It prevents moisture from penetrating the mattress, even if you spill something or have an accident. Compared to conventional products, it features a five-sided waterproof design, covering not only the bed surface but also the sides, expanding the covered area. With its high water resistance, it reduces discomfort from moisture, keeps you feeling fresh, and allows you to sleep soundly all year round! 【Comfortable Feel & Breathable Durability & Improved Sleep Comfort】Made with peach skin processing and 100% polyester material, it offers a comfortable touch and excellent breathability. The use of 90g brushed material and careful construction results in a thick box sheet that resists shrinking, deformation, pilling, and wrinkles, ensuring high durability and long-lasting use. The smooth texture feels pleasant against the skin, making it suitable for everyone from adults to children, providing comfortable sleep every day! 【Absorbent & Quick-Drying & Anti-Mite & Antibacterial】This box sheet is absorbent and quick-drying, drying in a short time after washing. It prevents the accumulation of dandruff, dead skin cells, and moisture on the mattress, which are food sources for mites, thereby inhibiting mite proliferation. Furthermore, everyday use can lead to unsanitary conditions due to spills and stains, potentially leading to bacterial growth. Using this quick-drying sheet allows for regular washing, ensuring cleanliness and protecting your family even on rainy days. 【Easy to Attach in About 15 Seconds! & All-Around Elastic Protection & Wide Applicability】The box type with elastic all-around rubber fits snugly over the corners of the mattress, making it easy to attach even for women! Also, it won't come off even if you toss and turn, preventing it from slipping. It accommodates mattresses up to 30cm thick, with multiple sizes available, and is suitable for most commercially available mattresses. Recommended for children's bedwetting, elderly care, and hygiene measures. 【Machine Washable & Available in Multiple Colors!】You can easily wash it at home, ensuring it's always clean and hygienic.
