This is a bed cover for semi-single to single beds (^^) Made of microfiber material, it feels great against the skin and is warm (^^) It's easy for one person to remove, so it's a must-have item♪ [Free Size + Box Specification 360° Protection] It is 80-100cm wide x 190-210cm long, with a 35cm deep pocket. The entire sheet has reinforced elastic, so it fits semi-single to single-sized mattresses and futons with a thickness of 3-30cm, and it wraps them securely. [Flexibility + Stretches Vertically and Horizontally] Made with crystal microfiber fabric, which is woven with finer fibers than flannel, the supple and soft feel is further enhanced! It has the best silk-touch feel. Because it's a stretch material that stretches both vertically and horizontally, it's wrinkle-resistant and fits the mattress perfectly. It's a box sheet that fits various sizes of mattresses, futons, and even three-fold mattresses. [Unique Border Pattern] By creating threads with different color development rates and dyeing them with dye, a beautiful border with a balance of light and dark colors was created. It gives off a slightly stylish atmosphere. Customers who are tired of plain colors should definitely give it a try. [Non-Slip All-Around Elastic + Easy to Attach/Detach] The box sheet has elastic all around, is stretchy, and fits perfectly just by stretching it. You can fold it up with the sheet still attached to the futon or mattress, which saves time. It won't slip even if you toss and turn. [Antibacterial and Odor-Resistant + Washable] The box sheet is treated with antibacterial and odor-resistant processing, so it's always clean and safe for people with allergies. You can wash it in a washing machine at home with a laundry net. We recommend purchasing two or more for replacement.
