Abstract: A computer holder has a protective case and a conformable backing which is attached to the case. The case holds the computer, and the backing can be formed as a soft membrane or as an accordion-like bellows. The backing is preferably made of a sewn fabric, leather and other similar soft materials, and may alternatively be made of injection molded silicone. The space within the backing can be selectively filled with small filling materials, a low viscosity fluid or a gas such as air. A two way valve, cap or handle can be attached to the backing to allow for a variation of the backing's fill level and shape. The holder can also have a strap attached to the case and a pocket formed in the backing.
