摘要：spring assembly for mattresses, innersprings, and the like. The assemblycomprises rows of coils (24,25,26), each row comprising a continuous length of wireformed into a plurality of coils interconnected by Z-shaped wire segments (18,28)alternately disposed at the top and bottom of the coils. Adjacent rows of coil areconnected by a helical wire (34) wound through overlapping Z-shapped wire segments.The overlapping connected segments on opposite sides of each coil are located in acommon diametrical plane of the coil so that complete compression of the coil does notresult in the coil being pulled laterally, twisted and distorted.
