ABSTRACT:
A stepladder, which may be in the form of a usual stepladder/stool combination, is provided with safety outboard frame members desirably of inverted U-shape providing upwardly arched hand holds extending upwardly beyond the upper step of the stepladder sufficiently to obstruct lateral movement beyond the ends of such upper step of the legs of a person standing on such upper step. The stepladder/stool combination in particular is preferably provided with a latching arrangement limiting movement of the safety frame members from safety positions during use of the stepladder and for not permitting the stepladder to be placed into condition for use until such safety frame members are in safety positions.
