Hi LowBackPain64,
I would keep in mind that there is no such thing as a mattress or a material that is “best” for any specific condition … only a specific mattress that is the best match for your unique needs and preferences in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences). There are too many unknowns, variables, and personal preferences involved for anyone to be able to predict which mattress may be “best” for someone else based on specs (either yours or a mattress) or “theory at a distance” (see mattress firmness/comfort levels in post #2 here).
The first place to start your research is the mattress shopping tutorial here which has all the basic information, steps, and guidelines that can help you make the best possible choices … and know how and why to avoid the worst ones (including the major brands or any other mattress that includes either lower quality materials or unknown materials in the comfort layers … see the guidelines here).
I would also avoid hotel mattresses (see post #3 here).
Once you reach step 3 in the tutorial if you let me know your city or zip code I’d also be happy to let you know about any of the better options or possibilities I’m aware of in your area.
