Tension relieving body support apparatus

A method of making a mattress comprising:

• bonding a core foam layer having a first indentation force deflection at twenty five percent compression, a first density and a first thickness to a first intermediate foam layer that is substantially coextensive with the core layer;
• bonding a top outer foam layer to the first intermediate foam layer;
• selecting the top outer foam layer to have a second indentation force deflection at twenty five percent compression, second density and a second thickness;
• selecting the intermediate layer to have a third indentation force deflection at twenty five percent compression, a third density and a third intermediate thickness;
• and
• wherein 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.
