ABSTRACT OF THE DISCLOSURE A chair rest member carried by the upper reach of a vertically extending back plate includes means providing for both vertical and angular displacement of the rest member rel- ative the back plate. A screw carried by the back plate en- gages a captive nut disposed within a vertical slot within the frame of the rest member to allow vertical adjustment there- between while angular or tilt adjustment is achieved by means of a screw wheel carried by the lower portion of the rest member engaging the juxtaposed face of the back plate and which, when actuated, tilts the rest member about a bearing surface above the captive nut. A curved washer attached to the captive nut permits retightening of the captive nut screw to fixedly retain the rest member in its alternate positions.
