ABSTRACT:
An apparatus for selectively disabling rocking the swiveling movement of a rocker-swivel assembly includes a pivoting member coupled to the top plate of the rocker unit and movable into engagement with the swivel base plate to prevent rocking and swiveling movement. A linkage assembly connecting a rod rotatable by the chair user and the pivoting member provides for actuating of the pivoting member into and out of such engagement. In another embodiment, the apparatus includes a threaded stem which selectively engages the top and bottom plates of the rocker unit and the swivel base plate.
