A detachable ladder is disclosed that includes a lower frame (10) including two substantially trapezoidal legs (11), a first board (13) interconnecting tops of the legs (11), and one or more crosspieces (14) interconnecting the legs (11); and an upper frame (20) including two side units (21) each including a substantially trapezoidal upper element having its forward end pivotably secured to a top front end of the leg (11) and a lower support extended downward from the upper element, a second board (23) interconnecting bottoms of the upper elements, a third board (24) interconnecting tops of the upper elements, and one or more fourth boards interconnecting intermediate portions of the upper elements. Pivoting the upper frame (20) about the lower frame (10) until the tops of the upper elements rest upon a supporting ground will convert the ladder into a chair.
