Hi puppylover,
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 your criteria and the quality/value guidelines here … the better options or possibilities I’m aware of closest to you are in the Lafayette, LA area (subject to the “value” guidelines I linked in my last reply) are listed in post #2 here and for Baton Rouge are listed in post #191 here .
