Hi RadioActivity,
You are fortunate that you live in Arizona because three of the members of this site are based there and all of them make great quality and value mattresses.
Post #4 here includes them and some of the other options you have available. I would definitely take a day trip to Phoenix ā¦ it would be well worth it IMO 
Out of over a dozen different stores in the Sedona, Flagstaff, or Prescott areas I looked at there is nothing Iām aware of that I would seriously consider outside of the single Flagstaff option that is listed in the Phoenix list.
