Abstract
A bedding foundation having a nestably stackable spring assembly, including a border wire having a generally rectangular cross-section. The foundation's spring assembly may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping. Each foundation assembly includes a number of corrugated support wires having alternating peaks and valleys. The border wire is generally rectangular in cross-section to reduce wire costs without compromising beam strength of the border wire.
