Hi nascarnole,
Just for clarity, I don’t make recommendations for stores unless they are a vetted member here of the site.
Aside from that, and subject to first confirming that any retailer or manufacturer on the list that you wish to visit is completely transparent (see this article) and to making sure that any mattress you are considering meets the quality/value guidelines here … the better options or possibilities I’m aware of in and around the Louisville, KY area are listed in post #3 here.
