It fits mattresses with a thickness of 3-26cm perfectly. The all-around elastic makes it stretch and fit perfectly on futons. You can also fold a tri-fold mattress as is, saving you the trouble. 【3D Stretch Fabric & Stretchy Bed Sheet & No Ironing Required】 To meet customer requests, we have created a sheet that fits beautifully and looks great. The fabric is a blend of polyurethane, which provides excellent elasticity, stretching freely both vertically and horizontally, making it easy to put on. It fits even odd sizes perfectly. It's wrinkle-resistant, so you don't need to iron it, and it fits beautifully. It also shortens the time spent on housework. 【Super Soft T-shirt Material & Comfortable All Season】 The fabric of the box sheet is like a T-shirt, with a soft and smooth texture that feels comfortable on the skin. It's designed to feel familiar from the start. It doesn't snag on the skin, so you can sleep comfortably without worrying about irritation. You can use it comfortably for a long time throughout the year, in warm seasons (spring and summer) and cold seasons (autumn and winter). 【0-Second Instant Absorption & Quick Drying & Always Clean】 The mattress cover has excellent breathability and moisture absorption/release properties. Especially in summer, it quickly absorbs and releases sweat, keeping you feeling dry. It's easy to care for at home in your washing machine, so you can always use it cleanly and comfortably. It's wrinkle-resistant after washing, making it easy to care for.
