This is a flat waterproof sheet (secured with elastic bands at the corners) to be placed over a futon. The surface has a towel-like texture, and the back is a waterproof sheet. I think it would be useful for households with children. The size is 193cm x 193cm, which can perfectly cover two single futons placed side by side. Please see the tag photo for the material. The color is blue. It has been used for 2-3 months, so there is a feeling of use.
