ABSTRACT:
A chair particularly suited for institutional multipurpose rooms, and the like, includes a base and a shell with a back and a seat which are constructed for generally contemporaneous movement. A first support connects the base with a medial portion of the seat to support the same in a cantilevered fashion, and is resiliently flexible to permit the shell to rock in response to fore-to-aft movement of a seated user. A second support connects the base with the back, and is also resiliently flexible to permit and control the rocking motion of the shell in a manner that provides improved comfort, and reduces sitting fatigue. Preferably, the support also permits the shell to move in a controlled manner from side to side in response to lateral movement of a seated user.
