ABSTRACT:
A chair has a seat that moves forward and backward with respect to its support, preferably in such a way that the front end is elevated somewhat as the seat moves forward, and a back that pivots between a substantially upright and an inclined position, depending upon the posture assumed by one sitting in the chair. The chair is of modular construction and embodies various parts, such as legs, back supports, arm rests and writing surfaces, that are interchangeable or can be added on or left off. Modular fittings are provided to join two or more chairs together.
