A chair control mechanism for use with a single stage gas spring construction for chair height adjustability includes a main control housing having an upwardly directed opening and an upper control housing having a downwardly directed opening. The two housings are dimensioned and configured to nest with one another and are connected by pivot members. An aperture is provided in the main control housing for receiving an end of a gas spring. A bracket assembly is welded to the main control housing and has two apertures both vertically aligned with the aperture of the main control housing and spaced above the aperture of the main control housing. The apertures of the bracket assembly are dimensioned and configured to engage a tapered end of the gas spring and support the control mechanism thereon with the end of the gas spring recessed well up into the control mechanism.
