Abstract: A low cost task chair comprises a blow molded seat support member having a central planar portion for attachment of a control bracket. A recess in the planar portion beneath the control bracket receives a cross brace. A pair of arm support frames are secured to the ends of the cross brace and to the control bracket. The arms are, therefore, easily assembled to the chair with the cross brace concealed from view. A pedestal is secured to the control bracket and contains a gas cylinder for raising and lowering the seat assembly. Another recess is formed in the seat support member for receiving a flush mounted cylinder actuating lever. A seat back adjustment mechanism for adjusting the outward position of the back relative to the seat comprises a pair of parallel spaced tubular members telescopingly received by the control bracket.
