Abstract
A mattress including (a) an innerspring, (b) one or more upholstery topper layers including an edge support that is a foam construction with at least two foam layers, and (c) one or more quilt panel layers. The at least two foam layers form the edge support or firming perimeter edge, wherein the first foam layer has ( ) a defined firmness, ( ) a thickness greater at its perimeter, and ( ) a central portion forming a receiving space. The second foam layer has a defined firmness less than the first foam layer and is nestably insertable into the receiving space of the first foam layer. The firming perimeter edge functions to provide a firmer mattress edge without compromising the thickness of the mattress or requiring additional materials or labor during manufacturing.
