The rocker cams are pivotally mounted to one of the base or seat frame and having arcuate surfaces engaged against the other of the base or seat frame. This achieves a predetermined desired motion of the seat relative to the base. In one embodiment, a pair of such rocking cams are provided in tandem on each side of the chair. In another embodiment, only a single pair of cams are provided in tandem at a central portion of the chair. In another embodiment three cams are provided in a triangular arrangement.
