Hate my Tempur Rhapsody, replacing with Aireloom or Prana

I was going to try and contact SF and Aireloom next week to see what type of foam is used on their upper layers.
What classification questions should I ask…such as what type of foam, ILD, weight?

It was mentioned that maybe the cover was still to firm, so today I unzipped it and had the sheets right on top of the latex, but still felt the same type of “up pressure” that is making me soar.

I did that the two Magniflex dealers in my are actually home decor type of stores and only have one of those models on display.
So they recommend going down to the Miami Magniflex Gallery (an hour south of me) to try all of them out. But if I were to order one, there is no exchange or return since Magniflex cannot resell or recycle used mattresses. So that right there would probably prevent me from every buying one.
