Abstract
A box spring corner guard is disclosed which protects and reinforces the corner of a box spring. The box spring corner guard consists of a curved body having the shape of a 90 degree section of an imaginary cylinder with a concave inner surface and a convex outer surface. A locator flange extends from the concave inner surface adjacent the bottom end of the curved body. Strengthening ribs run along the length of the curved body to add rigidity. In one embodiment, the curved body also has a limit flange, similar to the locator flange, extending from the concave inner surface adjacent the top end of the curved body. The curved body is attached to the base of the box spring, but the curved body is not attached to the border wire.
