Abstract: An adjustable suspension for attaching a piece of furniture to a wall includes a housing having an elongated supporting arm projecting therefrom. The upper edge of the arm is provided with a rough, preferably toothed, surface which engages a protrusion within the housing having a cooperating similar surface; and the lower edge of the supporting arm is provided with a rough, preferably toothed surface which cooperates with a rotatable cam in the housing having a similar surface. By moving the arm in translation through the region between the cam and protrusion, and by rotating the cam, the free end of the arm outside of the housing may be adjusted in both height and depth relative to the housing.
