Abstract of the Disclosure A collapsible scaffold. A pair of spaced apart vertical ladder configured frames include horizontally extending members upon which may rest a board or other supporting surface. A pair of cross members are pivotally mounted to the upstanding posts of the frames and have their outer distal ends positioned and hingedly secured together. A sleeve rigidly attached to one distal end of the cross member extends around the adjacent distal end of the second cross member. A window in the sleeve forms a stop surface through which a projection on the other distal end extends limiting the amount of relative motion between the cross frames.
