Abstract: A tilt control system includes a spring adjuster and compression spring, which may be removed in an unstressed condition. The tilt control system may also include a variable back stop having curved transition surfaces between the stop surfaces. A lumbar compensator may be integrated into a backrest, which may be coupled with a quick release to the base and actuated by sliding engagement with the seat.
