Niels Diffrient designed the Occasional chair to have the comfort and ergonomic features found in Humanscale task chairs, with lightweight materials in a multipurpose format perfect for guests. The Occasional chair’s seat cushion contours to the natural shape of the body for optimal comfort. The tri-panel backrest provides support without the need for any lumbar devices. The chairs stack 5 high. Made predominantly from lightweight 100% recycled aluminum, the Occasional is long-lasting and environmentally friendly. Its modular design means it can be customized and easily updated as needed.
