Abstract
Disclosed is an improved innerspring unit for a mattress using a plurality of formed wire elements for support. Enhanced lateral and longitudinal stability of the improved innerspring is provided by one or more stabilizing features including dual formed wire elements, complimentary recesses to secure the intersection of longitudinal and lateral wires and formed wire elements disposed on the edges of the unit which are formed of the same wires which extend longitudinally and laterally across the unit. A variety of different formed wire elements is disclosed, each of which provide different support characteristics. By varying the type, number and location of the different formed wire elements, a particular support profile may be provided which may correspond, for example, to the weight contour of a prone human body.
