Hi amr2625,
Thanks for the feedback … I appreciate it
The idea of softness and firmness has many different parts and a mattress can be softer in one way and at the same time be firmer or more supportive (or evenly supportive) in another way. There is more about what I call the different “types” or “species” of softness in post #15 here. There is also more about the relationship between what I call primary support, secondary support, and pressure relief in post #4 here. In my conversations with Peter he clearly understands this so rating a mattress as softer or firmer really depends on which type of softness or firmness you are discussing.
“Overall” … the Supreme would “feel” firmer than the Luxe but it’s also true that the Luxe has higher density materials which would be more conforming and more evenly supportive which means that for some body types it could lead to better alignment. This is all part of the “art and science” of mattress construction.
The HD series use higher density foams yet so they can be even more “supportive” even though they won’t “feel” as soft as mattresses that use 4 lb memory foam. The perception of “overall softness” is very subjective and it’s usually much more effective to focus on PPP rather than just how soft or firm a mattress “feels”.
This is one of the challenges with memory foam because it changes in response to temperature, humidity, and the length of time the material is compressed (as well as on the age of the mattress and whether the materials are new or are already broken in). Different people will also have different perceptions of the same mattress even if they are similar in body type and sleeping positions because each person has their own “definition” of soft and firm.
Based on my conversations with Peter … the good news is that he clearly understand all of this and can help you use your experience on your Cirrus Luxe as a reference point for deciding which mattress may work best for you
