Hi pslieber,
I think yesterday was my day for skipping over some posts or questions in various threads 
Besides the online options you “discovered” … there are also some factory direct manufacturers options in the Baton Rouge area that also use high quality materials including memory foam in their mattresses.
Local manufacturing can be the best of both worlds because you can actually test the mattresses in person and the quality and value is usually much better than any other options in the area. For those who don’t have good quality local manufacturers in their area … then online options can also make a lot of sense and make provide the same kind of quality and value for everyone else.
You’ll find a list of them in post #191 here.
