Abstract
A bedding mattress including a spring assembly, the length of which is divided into three zones, the center zone of which includes rows of springs, each row of which is formed from a single continuous length of wire and contains a plurality of coils interconnected alternately in the top and bottom planes of the spring assembly to springs of the same row. The end zones include rows of coils, each coil of which is independent of the adjacent coil and is formed of a single length of wire knotted at the ends to form a knotted end turn or revolution. The rows of coils in all zones are interconnected by helical lacing wires, and the rows of the center zone, which are located adjacent the rows of the end zones, are also interconnected by helical lacing wires. Three border wires surround and are connected to the edgemost springs of the assembly by helical lacing wires.
