Hi MFC Memory Foam Comfort,
I’m not sure I understand the reasoning behind your assessment about resilience affecting pressure relief which is more about softness, the point elasticity of the foam, the compression modulus of the foam, and the depth of the pressure relieving cradle and in the case of memory foam the temperature response of the foam as well (see post #4 here).
If I look at either your Skygel mattress or your Cumulus mattress … both of which have 4" of memory foam (1/2" less than the Cool Supreme) … they are both rated as soft which means that both of them would likely have thick enough comfort layers to isolate someone from the firmness of the support layer underneath them for most people (or they would feel firmer than “soft”).
If I look at the Stratus mattress on your site which has the type of layering you are suggesting (memory foam over a more resilient material) with the same 4" comfort layer thickness … it is rated as “medium soft” which is firmer than both of your memory foam mattresses with 4" of memory foam.
While I can certainly understand the appeal of using a thinner memory foam layer over or under a layer of more resilient foam for those who prefer this type of more resilient and responsive “feel” compared to just a thicker layer of memory foam which has no resilience at all (and I personally like this type of more resilient hybrid foam combination) … I don’t see how resilience (how “bouncy” a foam is) would affect the softness of the comfort layers or the effectiveness of the pressure relieving cradle since resilience and softness aren’t related.
All types of foam including higher resilience foams (like latex and energia) and low resilience foams (like memory foam or gel memory foam) become firmer and more resistive to further compression as they are compressed more deeply (which is their compression modulus) and regardless of the type of material used in the comfort layers, the pressure relief will be affected by these 4 specs (softness, compression modulus, point elasticity, and thickness) along with temperature response in the case of memory foam more than by the resilience of the foam.
