Hi Conflicted,
In my opinion not at all and this is all part of what I call each person’s personal value equation. There is no “right or wrong” in this … just the importance or “value” you place on having more design flexibility vs cost which is more important to some and less to others. It certainly opens up many possibilities for experimentation and fine tuning.
You can see some of my thoughts about thicker mattresses and their potential benefits in post #14 here and some thoughts about layering possibilities that come with having more layers are in post #2 here.
As a reference … the specs of the Beautiful are here and as you can see it has 6" of soft latex in the comfort layers which could be a somewhat “risky” choice for people who are on the heavier side in terms of support and alignment. It could easily “allow” your heavier pelvic girdle to sink down too far relative to other parts of your body for ideal spinal or joint alignment.
