Abstract
A mattress spring assembly is disclosed having increased firmness in a preselected center area of the mattress. This increased firmness is achieved through use of a grid structure attached to the opposite sides of the mattress. This grid structure comprises plastic straps extending diametrically across the mattress in the center third area and overlaid by a preformed wire grid. The plastic straps and wire grid are attached to the preassembled spring core by conventional connectors such as metal clips and/or hog rings.
