Abstract
A chair height adjustment mechanism which can be retrofit to a chair comprises a rod with a circumferential notch proximate one end for insertion through openings in the chair seat support bracket above a valve opening member of the chair height adjustment cylinder such that the rod is free to tilt against the valve opening member. The circumferential notch receives the looped end of the inner wire of a co-axial cable. The sheath of the cable is supported by a flange of a support member. The support member has an opening which receives the adjustment cylinder and a wheel which redirects the inner wire from the rod toward the flange. The other end of the co-axial cable terminates in a user actuator which may be mounted to the underside of the chair seat.
