发明名称 Longitudinally laced posturized and/or contoured spring bedding product
摘要 A spring interior comprising a plurality of transversely extending bands of springs disposed side by side and connected together by longitudinally extending 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 spring interior is characterized by sections of differing firmness or height throughout the length of the spring interior, which differing firmness or height sections are created by either having the wire from which the bands of coil springs differ in physical characteristics or by having the coil springs of the differing bands differ in height when in the relaxed state.
