--- "DO IT YOURSELF" ENTRY ------- Description: A raised, horizontal work surface, exactly the same size and shape as the lap tray or the cut-out desk that it is placed on.
PURPOSE: To improve sitting posture and arm control during functional table-top tasks, for certain students who have severely increased tone, very low muscle tone, and/or severe muscle weakness. A student who requires a raised table surface often also benefits from using a lap tray or cut-out-desk so the arms are fully supported.
1.Sheet of 2 inch thick, 2 pound density polyethylene (hard) foam, same size as the lap tray or desk top.
2.Triwall material same dimensions as the polyethylene (hard) foam.
3.Attractive contact paper.
4.Pressure-sensitive Velcro hook and loop tape.
5.Heavy brown paper to make pattern.
Razor knife, band saw, steak knife or jig saw; electric knife, pencil or marker, heavy-duty scissors
Whether a lap tray or cut out desk is used, the easiest measuring procedure is to make a tracing of the desk top or lap tray (including the sides that support the arm) rather than using a measuring tape.
1. Make a pattern by tracing the cut-out desk top or lap tray onto brown paper and cutting the shape out. Trace the pattern onto the polyethylene foam. Cut out the foam using the electric knife.
2. Use the same pattern, cut out a piece of Triwall.
3. Cover the Triwall with contact paper. If desired, cover the side edges of the polyethylene foam with contact paper, wrapping the contact paper over onto the top and bottom a few inches to keep it from peeling off.
4. Attach the Triwall to the top of the polyethylene foam using pressure-sensitive Velcro hook and loop tape.
