A collapsible support includes a cross member and a pair of collapsible support brackets having pairs of generally tubular legs extending therefrom. Each support bracket includes a generally planar base member secured to the cross member and a pivotally attached leg carrier. The leg pairs are secured to the leg carrier and are pivotable therewith from extended load bearing positions to collapsed storage or transport positions. A spring lock mechanism is provided which engages a portion of the leg carrier in the extended load bearing position and secures it in a releasable attachment in the load bearing position.
