Hi mwallbrecht,
You’re right that “Phoenix” is probably the most difficult search term on the forum if you are looking for anything other than my username!
In any case … the better options and possibilities I’m aware of in and around the Phoenix area (subject to the quality/value guidelines here) are listed in post #4 here.
You are very fortunate to live in the Phoenix area since several of the manufacturing members of this site are based there which gives you the chance to test mattresses in person that most of the rest of the members that live in other areas of the country can only order online without being able to test them first.
