ABSTRACT:
A spring interior comprising a plurality of longitudinally extending bands of springs disposed side by side and connected together by helical lacing wires in the top and bottom faces of the bands. Each band of springs comprises a single length of wire formed into a plurality of substantially vertical coil springs interconnected by interconnecting segments of wire located alternately in the top and bottom faces of the bands. The endmost coil springs of each row are interlaced for the length of the coil with the next adjacent coil of the same row such that the axes of the last two coils in each row are substantially coaxial.
