HEIGHT ADJUSTOR FOR FURNITURE ABSTRACT OF THE DISCLOSURE A height adjustor for furniture, such as chairs, and the like, comprises a pair of telescoping tubular members which interconnect base and seat portions of a chair and form a supportive pedestal therefor. A ram is mounted in the tubular members, such that extension and retraction of the ram respectively raises and lowers the chair seat. The ram and tubular members are sized in a manner to form an annular space therebetween which permits the ram to assume an eccentric position in the tubular members during a loaded chair condition. The ram ends are pivotally connected in the tubular members, such that lateral forces (as distinguished from vertical forces) which are applied to a chair seat are supported primarily by the tubular members, and are not transmitted to the ram. - 1 -
