The invention relates to a foldable stand (1) comprising a longitudinally extending support (2) which is carried by two legs (3), each leg (3) being connected to the support (2) via a journal (4) having a central axis (5), said stand (1) being foldable between an operational position, in which the legs (3) extend in one plane and the support (2) extends away from said plane and a rest position in which the legs (3) extend in said plane and the support (2) also extends in said plane substantially parallel to the legs (3), wherein a housing (6) is provided to which the support (2) is fixedly mounted, and a coupling element (7) is provided in said housing (6) for rotationally coupling the central axes (5) of the journals (4) of the legs (3) at an angle relative to each other. Folding of the stand between the operational position and the rest position requires only one operation from a user. By moving the support from its operational position the legs are automatically taken along from said operational position into said rest position.
