Hi yardbirdjeepeer,
I think that Denver mattress is likely to be among if not the best value in your area and if you have tested these so you know they are suitable for your needs and preferences … they certainly have good value.
You’ve probably seen this but post #2 here has some of the better options in the Midland/Odessa TX area (and I made a few calls and updated it today in case you want to include some other possibilities in your research).
