ABSTRACT:
A device adapted to stabilize an article of furniture on a support surface is formed as a wedge-shaped main body having upper and lower surfaces diverging from a common vertex to an end surface. A plurality of transverse rib teeth are on at least one of, but preferably both of, the upper and lower surfaces so that a plurality of devices may be stacked with the teeth preventing longitudinal slippage. The construction material is stiff, yet flexible and resilient, to help stabilize the article of furniture, and may be an anti-skid material. A cavity may be provided to enhance selected flexing, and ridges may be provided to prevent lateral slippage. The upper and lower surfaces have a common radius of curvature and may be planar or, respectively, convex and concave. The upper and lower surfaces may come together at a point, a line or a blunt nose to define the vertex. A bore may be formed through the body member for mounting and carriage.
