Abstract: An improved multi-purpose piece of furniture which is usable as a chair and as a step-ladder. The arrangement has a base frame and a backrest which is pivotally mounted on the base frame and adapted to be folded from a backrest position to a step-ladder position and vice versa for respective use as the top rung of the step-ladder when it is in a horizontal position and as the backrest of a chair when it is in the backrest position. The arrangement includes a pair of connected frame members forming the base frame. A plurality of rungs are operatively mounted on one of the frame members. The top rung of these rungs is adapted to alternately and selectively form a backrest or a step-ladder rung. An imaginary vertical plane passing through bottom rear edge of the backrest, when it is in the step ladder position is disposed in front and spaced from the front edge of the bottom rung which is connected on the one frame member.
