Abstract: A collapsible horse for supporting planks and the like wherein the collapsible horse comprises a stringer and laterally opposite, downwardly divergent extending legs which are carried at each end portion of the stringer. The stringer is in the form of two telescopically engaged tubular members with an inner tubular member having a length which exceeds the length of the first tubular member such that a pair of downwardly extending legs is attached to the longer member while a second pair of legs is attached to the shorter member. The two members are rotatable with respect to each other so that the legs may be extended and collapsed as desired.
