This lightweight platform creates a comfortable, flat surface on your lap to provide stability for a laptop computer when a tabletop or other work surface is unavailable. The lap desk surface has a slightly raised perimeter that gently elevates your laptop to allow air to circulate under the computer, ensuring proper ventilation while insulating your knees and thighs from contact with the computer underside which can become heated with prolonged use. The surface is slip-resistant to prevent a laptop from drifting or sliding during use, and the underside of the lap desk is softly padded to rest gently on the legs. A short strap on the back keeps cables neatly collected, and the lap desk is large enough to accommodate 17" laptops. 1 1/4" H x 18" W x 12" D. (15 oz.)
