A method of increasing the firmness of one or more portions of a mattress spring core, which spring core comprises a plurality of springs each having an upper face disposed in an upper plane and a lower face disposed in a lower plane, said springs being arranged in rows and columns, which method comprises:

• wrapping helical lacing connectors of different gauge wire around portions of said upper and lower faces of adjacent rows of coil springs in different regions of said spring core, said helical lacing connectors being of identical gauge wire in each separate region of said spring core so as to increase the firmness of at least one region of said spring core, each of said helical lacing connectors encircling adjacent portions of adjacent faces of adjacent rows of coil springs.

A bedding mattress spring core having a relatively long longitudinal dimension and a relatively shorter transverse dimension, said spring core comprising a plurality of helical coil springs each having a central spiral portion defining a central spring axis and terminating at opposing ends in upper and lower end turns disposed in planes substantially perpendicular to said spring axis, said coil springs being arranged in side by side transversely extending rows, a plurality of transversely extending helical lacing connectors, said coil springs being connected with each other at said upper and lower end turns by said helical lacing connectors arranged in said planes such that each of said helical lacing connectors encircles adjacent portions of said end turns of adjacent rows of said coil springs, said mattress being separated into multiple longitudinally extending regions, each of said longitudinally extending regions having at least two spaced helical lacing connectors therein, said longitudinally extending regions being of differing firmnesses, said differing firmnesses being attributable, at least in part, to said helical lacing connectors being formed of a heavier gauge wire in one longitudinally extending region of said spring core than the gauge of said helical lacing connectors in other longitudinally extending regions of said spring core.
