Claims5
A spring assembly for a mattress or cushion or the like having at least a peripheral row of vertical open-coil helical wire springs and top and bottom border wires to which said springs are connected, said springs in at least selected zones of only said peripheral row along each side of said assembly being interleaved with their top and bottom convolutions in overlapping engagement to reinforce the side edges of the assembly.
A rectangular spring assembly for a mattress or cushion or the like comprising aligned transverse rows of vertical, open coil helical wire springs connected together within each row and between rows by transverse helical tie wires threaded about the juxtaposed portions of the top and bottom end convolutions of the springs of adjacent rows;
- top and bottom border wires connected to the peripheral springs of the assembly;
- and additional springs of the same height and construction as those of said rows inserted along the longitudinal side edges of the assembly into the spaces between adjacent springs along the longitudinal edges of the assembly with the end convolutions of said additional springs engaging the insides of the top and bottom end convolutions of said connected edge springs in supporting engagement therewith, being crossed diametrically by said transverse tie wires, and connected to said top and bottom border wires respectively to secure said additional springs in said inserted position.
