Abstract: A removable working surface for a common desk drawer which is a rectangular block of width and length enough to fit atop most desk drawers and thick enough to be sturdy yet light. The bottom surface has two smaller blocks which are nearly as long and thick as the surface, but a fraction of the width. The blocks can be adjusted side to side to fit the inner side walls of a desk drawer, preventing shifting. To adjust the blocks, the screws attaching the blocks are loosened, the blocks moved to the desired position, and the screws re-tightened. Access to the drawer is still easy; simply lift the front of the surface, or remove it completely.
