What IFD/ILD would be ideal in this situation?

Hi E.J.M,

[quote]What do you usually call the different layers?

I mean, I have heard like “base layer”, and “comfort layer”. Any other layers out there, if you know what I mean?[/quote]

There is no specific name or definition of all the layers but the layers on top of a mattress that provide most of the pressure relief are generally called “comfort layers” and the deeper layers that are mostly responsible for the primary support of a mattress are generally called the “support core” or the “support layers” or the “base layers” and the layers in between (if there are any) that have a more dual role are generally called “transition layers”.

There is also more about primary or “deep” support and secondary or “surface” support and their relationship to firmness and pressure relief and the “roles” of different layers in a mattress in post #2 here and in post #4 here that may also be helpful in clarifying the difference between “support” and “pressure relief” and “feel”.
