Hi FMatch,
Post #2 here has some links to some of the more generic design theory that may give you some preliminary guidelines (although there are too many individual unknowns and variables to use them for specific people) but the best way to know which mattress is most suitable for your needs and preferences in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) is either personal testing on a mattress (or a mattress that is a very close approximation of an online mattress) or more detailed phone conversations with an online retailer or manufacturer themselves. They know more about their specific mattresses and which designs have the best odds of being suitable for you than anyone else and can use their knowledge and experience with the options they have available to give you good suggestions based on your height and weight and any more detailed input you may have from local mattress testing based on “averages” and feedback from their customers. Both of these are much less complex than using specs (either yours or the specs of a mattress) to design a mattress based on “theory at a distance” … which can easily lead to information overwhelm or “paralysis by analysis” because of the steep learning curve involved … especially without specific reference points of mattresses you have tested in person.
It’s much easier to “find the experts” or “work with the experts” that make or sell a mattress you are considering and who already know what you would otherwise need to learn than to begin the journey of becoming one yourself
