A step stool comprising an upright arm (1), to which tread surfaces (4, 5) are articulated by pivot spindles (13, 16), which tread surfaces are linked together by at least one guide strut (15), and articulated to the upright arm (1) a support arm (11) to which at least one of the tread surfaces (4) is articulated by means of a guide spindle (7), characterised in that the at least one tread surface (4) articulated to the support arm (11) is arranged rotatably to the guide spindle (7) on the support arm via hinge arms (8) which are foldably mounted at the ends of the upper support bars (11b) of the support arm (11) by a respective swing pivot (3), and in that a pawl (9) is rotatably mounted on at least one swing pivot (3), in the angled slot (14) of which pawl, for locking in the swung-out position of the tread surface (4), lies the pivot spindle (13) associated with this tread surface and with the upright arm (1).
