A computer stand for use with a tablet computer comprises a frame with a viewing aperture. The tablet computer is secured to the back of the frame with a pair of brackets, each of which consists of a structural angle having a cutout in one flange that is equal in depth to the thickness of the tablet computer. The other flange of the structural angle has a cutout that is bounded by a pair of horns that engage the rounded corners of the tablet computer. The first cutout traps the tablet computer against the back of the frame while the second cutout prevents the tablet computer from moving sideways. Because the brackets are structural channel members, the brackets add rigidity to the frame, which otherwise would be unacceptably flexible or would require additional structural reinforcement.
