Hi Bennyb,
There is only an inch of lower density quilting foam and all the other materials are high quality and durable materials so the mattress would easily meet the guidelines here and there are no weak links in the mattress in terms of durability.
If your testing has confirmed that the mattress is a good match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) and it compares well to your other finalists based on all the other parts of your personal value equation that are important to you then it would certainly be well worth considering.
