Abstract

A bedding or seating product comprising a spring core including upper and lower border wires. Each of the border wires is generally rectangular in cross-section to reduce wire costs without compromising beam strength of the border wire. Each row of springs of the spring core may be made of a single piece of wire. The rows of springs may be arranged in side-by-side rows and columns and be connected with each other by helical lacing wires.
