Abstract
An office-type chair having a base, a cantilevered pedestal assembly projecting upwardly from substantially a center of the base, and a seat/back arrangement connected to an upper end of the pedestal assembly. The seat/back arrangement includes a generally horizontally enlarged seat assembly and a back assembly projecting upwardly from and adjacent a rear edge of the seat assembly. The seat/back arrangement also includes a rear tilt control mechanism for normally permitting the seat/back arrangement to be vertically tilted rearwardly against the urging of a resilient biasing element away from a normal upright position into a rearwardly tilted position. A front tilt mechanism cooperates between the pedestal assembly and the seat assembly for permitting the entire seat/back arrangement to be vertically tilted forwardly away from the normal upright position so that the seat assembly declines in a forward direction. The forward tilt mechanism is independent of the rear tilt control.
