ABSTRACT:
A spring wire core for use in bedding mattresses and/or upholstered furniture cushions and the like comprised of a pair of half units. Each half unit includes a surface portion and a plurality of springs projecting in one direction from the surface portion. Connecting elements are provided to enable a pair of half units, one inverted relative to the other, to be connected together forming a wire core with two spaced surface portions. Preferably, the spring portions are configured to enable a plurality of the half units to be nestably stacked one upon another to enable efficient shipping of the half units without compression of the spring portions.
