ABSTRACT A ladder comprises a pair of main stiles, a series of centrally-hinged rungs with ends articulated to the two main stiles, whereby the ladder can adopt a folded inoperative configuration in which the main stiles are alongside each other and an extended operative configuration in which the main stiles are spaced from each other, and means for stopping the ladder in the extended operative configuration. The main stiles are articulated together at their upper ends and the ladder further includes a single auxiliary stile articulated at its upper end to the two upper ends of the main stiles about an axis substantially perpendicular to the articulation axis of the two main stiles. The auxiliary stile is movable between a position alongside the two main stiles, corresponding to the folded inoperative condition of the ladder, and a position spaced from the main stiles, corresponding to the extended operative condition of the ladder.
