Hi bsleepn,
In terms of suitability and PPP (Posture and alignment, Pressure relief, and Personal preferences) your own careful testing is the most reliable way to know which mattress is the best “match” for you but I would make sure you do some careful testing to make sure that the mattress isn’t too soft for you to provide good alignment in all your sleeping positions.
In terms of durability … you can see the guidelines I would suggest for foam quality/density here and there is also more information in post #3 here that would be helpful for those that are in higher weight ranges.
