Hi 2manybeds,
There is more about Charles P. Rogers in this thread which would be well worth reading. Outside of carefully and obectively testing a mattress for PPP (Posture and alignment, Pressure relief, and Personal preferences) using the testing guidelines … a mattress is only as good as its construction and the quality of the layers and components inside it. Once you have this information you can identify any weak links in the mattress and make meaningful comparisons to other mattresses. Without knowing this you would be making a blind purchase and there is really no way to know the quality/durability of a mattress. The information you need to assess a mattress is in post #4 here and if you can find out and list the layers and components of any of their mattresses you are considering I’d be happy to make some comments about the quality of the materials or help you identify any weak links in the mattress.
