Abstract: An elastically deformable base is configured to seat against the back of a tablet computer. Four arms extend diagonally outwardly from a central portion of the base around and against the sides of the computer and toward its corners. The arms each have an inwardly directed flange extending onto the edge of the face of the computer for retaining the computer against the base. The base also has a plurality of releasable, base mounted strap connectors at spaced-apart attachment points on the base. A pair of straps is connected to the base. Each strap has at least two, strap mounted connectors that mate with the base mounted strap connectors and detachably attach the strap to the base.
