Tatami originally means "folded and piled" and are a traditional type of Japanese flooring. Traditionally made of rice straw to form the core though nowadays sometimes the core is composed of compressed wood chips or polystyrene foam, with a covering of woven rush straw. Usually, on the long sides, they have edging of brocade. In almost all Japanese homes, temples and restaurants, one can find fusuma, which slide from side to side to redefine spaces within a room, and also act as doors. They typically measure about the same size as a tatami mat, and are two or three centimeters thick. They consist of a wooden frame, covered in cardboard and a layer of paper. They typically have a black lacquer border and an indented door handle. Historically, fusuma were painted, often with scenes from nature such as mountains, forests or animals.
