ABSTRACT:
An improved wire grid for connecting an array of coil springs in a box spring assembly includes perpendicularly-connected lengthwise-extending and widthwise-extending wires with the widthwise-extending wires arranged in sufficient number of possible groupings, each of three successively adjacent wires, spaced along the length of the grid to enable the grid to accept plural differing arrays of coil springs by utilizing varying combinations of the wire groupings for use of the grid without modification in box spring assemblies having differing spring-supporting base frame constructions.
