Hi jlyr3mixed,
The better options or possibilities I’m aware of in and around the Dallas/Ft Worth areas (subject to the quality/value guidelines I linked in my last reply) are listed in post #4 here.
I would check their websites and then call and talk with the ones that interest you the most to confirm that they carry mattresses on their floor that fit your budget and quality/durability criteria and that you would be interested in testing before you visit them.
