Purchased in 2024 but never had the chance to use it. Opened and washed. Color: White (Tencel fabric) Material: Surface - Lyocell (regenerated fiber, natural material) 100% Lining - Polyurethane (waterproof TPU) Gusset - Polyester 100% Size: Double - 140X200cm Pattern: Solid ● Uses advanced knit technology to significantly reduce "rustling sounds." ● Filled with moderately voluminous padding for a fluffy feel. ● Fully waterproof! Prevents moisture from reaching the mattress! Using a waterproof sheet prevents moisture from penetrating futons and mattresses, reducing discomfort and ensuring a comfortable sleep. ● Excellent absorbency and diffusion; the terry cloth disperses moisture, keeping the surface feeling dry even when wet. ● Used for pet protection, bedwetting protection for children, incontinence protection for the elderly, and as a hygiene sheet. Washing frequently keeps it clean and hygienic. Specifications: The gusset is approximately 35cm. It's a box type with anti-slip elastic, so it fits perfectly on mattresses with a thickness of 3-30cm! Can be used for beds, mattresses, and futons. Easy to put on and take off, even if you toss and turn in your sleep. Machine washable: You want to use a clean box sheet every day that touches your bare skin. With this cover, you can always keep your futon clean and comfortable. Safe for children. Notes: ※ Use the "delicate" cycle and a "laundry net." ※ Do not use a dryer. ※ Cannot be used with heat sources such as electric blankets.
