ABSTRACT:
An adjustment device for chair arms and the like allows releasable adjustment by the user without the necessity of tools or levers. A mounting member is provided with an elongated slot for engaging and limiting the travel of guide posts which are affixed to a structural member. The adjustment device is generally attached to the underside of a chair seat and includes disk-shaped springs which provide sufficient compression to allow manual movement yet maintain the selected position when the manual force is terminated.
