A collapsible work support comprising a first part having an elongated cross member and two spaced substantially parallel legs extending angularly from said cross member, a second part having an elongated cross member and two spaced substantially parallel legs extending angularly from said last named cross member, said cross members being formed of metal tubing of rectangular cross sectional shape and said legs of each part extending at an angle to and secured to two surfaces of said rectangular cross member, the cross member of the first part including an elongated integral extruded part-cylindrical joint-forming member projecting from a corner thereof the cross member of the second part including an elongated integral extruded socket-forming member projecting from a corner thereof, said projecting cylindrical and socket members interfitting at the lower inner corners of said cross members when assembled to accommodate limited pivotal movement of said first and second parts between a position in which adjacent faces of said tubes abut and the legs of said first and second parts diverge downwardly and a position in which the legs of opposite parts are substantially parallel, and a folding brace connected to legs of said first and second parts intermediate their length to limit relative longitudinal movement of said first and second parts, and accommodate pivotal movement thereof.
