ABSTRACT:
According to the present invention, a control system for a chair is provided. The control system is comprised of first and second resilient blocks, first and second stabilizing members and first and second rockers. The first stabilizing member has first and second ends and defines a first horizontal axis. The first end of the first stabilizing member extends into the first resilient block and the second end of the first stabilizing member extends into the second resilient block. The second stabilizing member is coupled to the first stabilizing member by a connector. The second stabilizing member has first and second ends and defines a second horizontal axis disposed in parallel to the first horizontal axis. The first end of the second stabilizing member is operably coupled to the first rocker, and the second end of the second stabilizing member is operably coupled to the second rocker.
