A first linear actuator pivotally moves the back portion into a desired position relative the base, and a linkage cooperates to cause a predetermined amount of pivotal movement of the seat portion relative to the base in response to pivotal movement of the back portion. A second linear actuator power means pivotally moves the seat portion into a desired position relative the back portion. Actuation of one of a plurality of switches cooperates with a control system for movement of the back and seat portions from one of the examination positions to at least a next following one of the positions within the sequence.
