Hi scott442,
If the layers you choose are a good match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) and you know the type and blend of the latex then it certainly sounds like a good plan.
You can also see my comments about the Reverie Mattresses in this topic.
I’m looking forward to your updates.
