ABSTRACT:
A mattress spring core having a plurality of zones of differing firmnesses due to different characteristics of helical lacing connectors within the particular zones. The spring core has a plurality of identical coil springs arranged in side-by-side transversely extending rows and columns. The coil springs are connected together at the upper and lower ends of the springs with helical lacing connectors which encircle a portion of the upper and lower faces of the springs. The helical lacing connectors may be of a heavier gauge wire in one or more zones of the mattress spring core thus causing that particular zone to be of an increased firmness relative to the other zones of the mattress. Alternatively, the helical lacing connectors within a zone may comprise two or more co-axial lacing wires to impart greater strength or rigidity to one or more zones of the mattress.
