Abstract
A chair comprises an integrally formed shell having a horizontal portion and a vertical portion. A seat pan is supported on resilient arms formed integrally with the shell. A pair of independently flexible arms of the vertical shell portion are formed integrally with shoulder support members. The resilience of the shoulder support arms and seat pan support arms provides a chair which is highly passive to the body movements of the user.
