This is a handy desk to have on your lap when working on your computer. When it is on your lap, it slants up and away, so the computer rests against the lip at the bottom. This lip is also where you rest your wrist when working. The desk keeps the computer off your legs which is more comfortable, and helps to dissipate the heat. On the back of the desk, are two fabric panels which are partly filled with beads, so it sits comfortably and reliably without sliding off your legs or whatever you have it resting on. There are also two zip pockets, for keeping cables or whatever. It has some scuff marks, but is in great working condition. Measures about 15” tall x 22” wide. The area where the computer sits is about 11.5” tall. It is made of plastic and fabric.
