The frame assembly includes a rear wall that includes a vertical drive track and at least one vertical gliding rail spaced laterally therefrom. A seat assembly is operatively coupled to the rear wall of the frame assembly and provides a seat on which a user can sit. A first drive assembly is coupled to the seat assembly and includes a ball scree drive mechanism to controllably move the seat assembly in a vertical direction along the frame assembly. A second drive assembly can be coupled to a swivel plate for controllably moving the swivel plate resulting in swiveling of the seat assembly relative to the frame assembly.
