An improved collapsible support structure having, in an erect position, a pair of vertical members interconnected by at least one collapsible or foldable support mechanism. The collapsible support mechanism has upper and lower substantially horizontal collapsible connecting members that are interconnected by diagonal support members forming an "X" positioned approximately halfway between the pair of vertical members. Each of the horizontal members is formed of a plurality of pivotally interconnected elements and at least one of the elements of one of the members is modified to maintain a desired angular relationship between the elements. A plurality of the collapsible support structures are combined together or interconnected to form improved collapsible or folding devices.
