Hi uccjeb,
There isn’t a forum list for Monroe, LA so I took a look around the area and the better options or possibilities I could see (out of about 15 local stores I looked at) and the manufacturers they carry I would focus on on a “mattress by mattress” basis (subject to the guidelines here) are …
Furniture, Mattresses in Monroe, West Monroe and Ruston LA | Burney's Furniture Monroe, LA. Englander
http://www.mattressplusla.com/index.html Monroe, Shreveport, LA. Pure Latex Bliss, Sleep Designs.
Best Discount Furniture Stores Near Me | Find local Furniture Near Me Monroe, LA and many others in the area. Restonic.
http://www.burnsandnewellfurniturela.com/index.htm Monroe, LA. Scandinavian (ADDED Mar/2015: they are closing these out so selection may be limited and there is nothing else here I would consider)
There aren’t a lot of great options in the area so it would be worth considering online options as well (which you are) but these would be the “better” ones I can see.
