Hi Gracey,
It sounds like you have already started doing some research and the specifications of the mattress above all fall within the recommendations of The Mattress Underground. If you have not done so, you may want to look at the - Mattress Shopping Tutorial as well as. and the [url=https://mattressunderground.com/our-articles/mattress-durability-guidelines-how-long-will-a-mattress-last/]Mattress Durability Guidelines to get an idea of what to look for in a new mattress and what different components and materials to review and how these hold up over time.
It’s not possible to make specific suggestions or recommendations for either a mattress, manufacturers/retailers, or combinations of materials or components because the first “rule” of mattress shopping is to always remember that you are the only one that can feel what you feel on a mattress and there are too many unknowns, variables, and personal preferences involved that are unique to each person to use a formula or for anyone to be able to predict or make a specific suggestion or recommendation about which mattress or combination of materials and components or which type of mattress would be the best “match” for you in terms of “comfort”, firmness, or PPP (Posture and alignment, Pressure relief, and your own personal preferences).
Please let us know what you decide to do
All the best!
