ABSTRACT:
A pedestal-type chair having a height-adjusting air spring connected between the base and seat assemblies, and a manually activated control for releasing the air spring. The control includes a small manually engageable activating lever pivotally supported interiorly of the seat assembly adjacent one side thereof and positioned so as to project slightly downwardly a small extent through the lower seat shell. This lever is connected to one end of an elongated flexible cable which extends interiorly of the seat assembly and has its other end connected to a force transfer lever positioned within the central interior of the seat assembly. This latter lever activates the valve-release member associated with the air spring.
