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 coil springs of each row are interlaced with the adjacent coils of the same row. The spring interior is characterized by sections of differing firmness throughout the length of the spring interior. The sections of greatest firmness have such increased firmness imparted by a plurality of posture rods which extend through interlaced portions of a plurality of pairs of interlaced coils of the spring interior.
