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 interconnected by interconnecting segments of wire coils of springs located alternately in the top and bottom faces of the bands. Each interconnecting segment comprises a longitudinally extending bridging portion and a transversely extending padding support structure. The padding support structure is angled upwardly away from the top face of the band and downwardly away from the bottom face of the band so as to impart initial softness and subsequent increased firmness to the spring interior when the spring unit is vertically compressed.
