Hi wimaine,
If the list you found was the one in post #2 here then it includes the better options or “possibilities” I’m aware of in the Columbus, OH area (subject to the guidelines here about the most important parts of the “value” of a mattress purchase).
I would probably have hung around for a bit as well … for the same reasons as you. With the story about the innersprings as well … I may have even considered asking his permission to take some notes to use in a comedy routine
