Zabuton

Traditional Japanese chair with a zabuton and a separate armrest

A Zabuton (座布団) is a Japanese cushion for sitting. The zabuton is generally used when sitting on the floor and may also be used when sitting on a chair. In a more casual setting, the zabuton can be used in conjunction with a zaisu (座椅子), a type of Japanese legless chair, with or without an accompanying kyousoku (脇息), a Japanese-style armrest. Ordinarily, any place in Japan where seating is on the floor will be provided with zabuton for sitting comfort. A typical zabuton measures 50–70 cm (20–30 inches) square and is several centimetres thick when new.

Zabuton are found throughout Japan and enter many aspects of the culture.
