Patent ID: 7703155

Claim:
A corner connector element for a mattress foundation assembly, comprising: a main body portion extending from a substantially planar bottom surface to a substantially planar top surface; a substantially planar first side surface of the main body portion; a substantially planar second side surface of the main body portion, wherein the first side surface and the second side surface are formed at substantially 90° relative to one another; a first abutment surface extending substantially perpendicularly from a terminating edge of the first side surface, wherein a first portion of the first abutment surface extends above the top surface and a second portion of the first abutment surface terminates at the top surface; a second abutment surface extending substantially perpendicularly from a terminating edge of the second side surface, wherein a first portion of the second abutment surface extends above the top surface and a second portion of the second abutment surface terminates at the top surface; a first corner abutment surface extending substantially perpendicularly from a terminating edge of the top surface adjacent to the first portion of the first abutment surface; a second corner abutment surface extending substantially perpendicularly from a terminating edge of the top surface adjacent to the first portion of the second abutment surface; wherein the first corner abutment surface and the second corner abutment surface are formed at substantially 90° relative to one another; and a radiused surface extending from a terminating edge of the first abutment surface to a terminating edge of the second abutment surface.
