Abstract
A mattress is provided having an innerspring, at least one upholstery layer, which includes at least one foam layer, and quilt panel layers. The upholstery layer has an edged support layer, a steel wire grid laminated to the edged support layer, and a firm foam layer laminated to the steel wire grid. The steel wire grid serves to provide support and to reduce the sagging effect caused when adding additional foam layers. The firm foam layer provides support distributed even across the mattress and may be used alone or in combination with the steel wire grid.
