A device that can be used as a case or a stand for a
portable computer is disclosed. The device comprising a generally rectangular sheet having first to fifth interconnected panels (16, 18, 20, 22, 24) disposed along a
long axis (A-A), the panels being interconnected by elements that allow them to fold with respect to one another about respective fold axes. The fifth panel has a
support surface upon which a computer can be supported, the third and the forth panels are, together, in the direction of the
long axis of approximately the same length as the fifth panel, and the first panel is of approximately the same dimension as the fifth panel. The first panel and the fifth panel carry fasteners (34, 36) such that a
free edge region of the fifth panel can be connected to a face of the first panel. In a first configuration, the fifth panel is folded to overlie the third and the forth panels to the underside of a computer, the first panel is approximately parallel to the fifth panel, to the top of a computer, and the second panel extends approximately normally thereto to the front of a computer. In a second configuration, the
edge region of the fifth panel is connected to the face of the first panel whereby the fifth panel, and a computer carried thereon, is supported on a slope by the fourth panel.
