The weight-activated mechanism includes a spring package connected between the chair frame and back upright which provides for ready mounting of same to the chair frame. Further, the rear seat portion is connected in lifting engagement with the upright but also includes independent suspension for the center of the rear seat portion to allow for independent movement and flexing thereof to improve comfort for the chair occupant.
