ABSTRACT:
A mattress including a core foam layer having a first indentation force deflection at twenty five percent compression, a first density and a first thickness. The top outer foam layer has a second indentation force deflection at twenty five percent compression, a second density and a second thickness. The first intermediate foam layer is intermediate and coextensive with the core layer and the top outer layer, and has a third indentation force deflection at twenty five percent compression, a third density and a third intermediate thickness. The first indentation force deflection is greater than the third indentation force deflection and the third indentation force deflection is greater than the second indentation force deflection.
