An attachment for a rung-type ladder which provides a generally horizontally disposed supporting surface such as a step. The attachment includes a pair of downwardly opening generally inverted U-shaped members which are positioned over a pair of adjacent ladder rungs combined with a pair of angulated support members attached thereto and provided with a laterally extending upper end portion which combines with the top surface of the uppermost ladder rung engaging member to attach and support a horizontal generally planar supporting member which extends laterally to both sides of the ladder stiles thereby providing a step to receive the shoes of a person using the ladder to provide comfort and stability thereto or support a paint tray, container, tools and the like. In a second embodiment, the basic structure is connected to the ladder in the same manner but includes telescopically adjustable extension tubes which form part of a stabilizer which includes an elongated cushioned member engaging the wall surface of a building to stabilize and support the ladder in spaced relation to the building wall. In a third embodiment, an optional inner platform is attached to the extension tubes to provide various supporting functions without adjustment. In a fourth embodiment, the wall engaging member of the stabilizer is omitted with outwardly curved end portions of the extension tubes engaging the wall.
