Hi sdmark,
Unfortunately no. I don’t know anyone in the industry that has enough knowledge or experience to be able to take all the unknowns, variables, and preferences involved to use specs alone (either of a mattress or a person) or “theory at a distance” to know with any certainty which mattress may be the best match for someone in terms of PPP. If there is … I have yet to find them and I’m certainly not one of them. It would be something like trying to define a “perfect” work of art for someone else.
The more knowledgeable and experienced someone is … the more they will tend to realize that each person is unique and even people with decades of experience that have designed and built many mattresses will often be surprised at the difference between the final outcome of a mattress and their design goals and how they thought it would feel and perform based on theory.
I tend to take a more “experiential” approach to choosing (or fine tuning) a mattress rather than a more theoretical or “spec based” approach which I don’t believe is effective and often leads to a focus on specs that have little practical use or meaning at the expense of actual experience. The specifications I pay most attention to are the specs that can help assess the quality/durability of a mattress and identify any potential weak links … not the “comfort” specs.
Once you have slept on a mattress and have a reference point based on your actual experience … then post #2 here and some of the posts it links to has more information about many of the more common symptoms and experiences that people will have on a mattress that can provide some insights about the types of changes someone may need if a particular mattress doesn’t seem to be suitable for them in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences).
