Zabuton

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. Ordinarily any place in Japan where seating is on the floor will be provided with zabuton, for sitting comfort. A typical square zabuton measures 50–70 cm (20–30 inches) on a side and is several centimetres thick when new.
