Hi johnehman,
Hopefully you’ve read the mattress shopping tutorial here which has all the basic information, steps, and guidelines that can help you with how to make the best possible choice … and know how and why to avoid the worst ones.
There is more about the most important parts of the “value” of a mattress purchase in post #13 here and the posts it links to that can help you make meaningful comparisons between mattresses.
Only your own careful testing and experience can know whether any mattress is a good match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) but outside of PPP a mattress is only as good as the type and quality of the materials inside it regardless of the name of the manufacturer that makes it so I would need to know what is inside the mattress to make any meaningful comments about it.
If you can find out the information in this article about the type and quality of all the materials in your mattress and post it on the forum I’d certainly be happy to let you know whether I can see any obvious weak links in the mattress or make some comments about the materials and components inside it that may be helpful.
If you do choose to include other manufacturers or retailers in your research then the better options and possibilities I’m aware of in and around the San Diego area are listed in post #2 here.
