The fitted sheet is available in single (100x200cm) and semi-double (120x200cm) sizes with a depth of approximately 30cm. The bed cover is made of flannel fabric, which uses ultra-fine fibers to trap air, providing warmth, and has a soft, silky feel and luster due to the dense fibers. The futon cover has an all-around elastic band on the back to prevent slipping, is easy to put on and take off due to its stretchability, and is compatible with mattresses, Japanese-style futons, and extra-thick futons. It is also anti-static treated for safe use in autumn and winter, can be washed at home for a clean and fluffy feel (however, use a laundry net when using a washing machine, do not use a dryer, and avoid using chlorine bleach). ----------------------------------------------------- "Size Information" Fitted Sheet: Single - 100x200cm, Semi-double - 120x200cm, with a depth of approximately 30cm.
