ABSTRACT:
A pedestal chair has a chassis with a mounting block (16) mounted on the pedestal, a main frame (18) supporting the upholstered seat and back and an intermediate member (20). The block (16) and the intermediate member (20) are pivotally connected about a transverse horizontal axis (22), and the intermediate member (20) is pivotally connected to the main frame (18) about a transverse horizontal axis (28). Blocks of resiliant material (26,32) urge the main frame (18) to a datum position from which it can pivot either forwardly about the rear axis (22) or rearwardly about the forward axis (28), on dependence upon the weight distribution on the chair. (FIG. 2).
