A Japanese-style bed is a type of bed that is traditionally made from a FUTON, which is a thin mattress that can be folded and stored away when not in use. It is usually placed on the floor and covered with a quilt or blanket. The FUTON is typically placed on a tatami mat, which is a traditional Japanese flooring material made from woven straw. This type of bed is popular in Japan due to its convenience and portability.
