ABSTRACT:
A generally flat add-on desk surface is provided with hooks and stop members so that the work surface can be attached to a tablet on a tablet arm chair. Hooks and fixed stop members engage side edges of the tablet to hold the added surface in position and a retractable stop member permits simple attachment and detachment. The surface is significantly larger than the surface of the original tablet and can be added for special purposes such as examinations and the like.
