An upper carriage, having a bottom surface and a top surface configured to receive the examination chair thereon, is supported on the upper surface of the base for movement between the forward and the rearward end thereof along the longitudinal axis to position the examination chair at the forward and the rearward position. A locking assembly is employed to releasably lock the carriage in a forward orientation disposing the examination chair at the forward position, and in a rearward orientation disposing the examination chair at the rearward position.
