Hi Pooswa,
There’s not a lot of factory direct manufacturers in most of Louisiana that I know of but there are a few in Baton Rouge.
http://www.wholesalemattressfactory.com/ Baton Rouge, LA. They have been in business for a very long time and make all types of mattresses using any material “the old fashioned way” with good quality and value. they will custom build whatever a customer may want. Open and honest and what I call “mattress people”.
http://www.capitalbed.com/ Baton rouge, LA. Another “old time” factory direct manufacturer who sells mainly wholesale to retail outlets across the state but will sell retail to a customer who walks in their door. Also carries a range of different types of mattresses on their floor including latex, memory foam, and traditional mattresses. Also very open and honest and “mattress people”.
http://www.istroumamattressfactory.com/ Baton rouge, LA. Yet another “old time” smaller (2 man) manufacturer who has been in business for decades. They also manufacture a range of mattresses of using higher quality materials including traditional innerspring/polyfoam, memory foam, and latex hybrids.
EDIT: There is one other factory direct manufacturer that I discovered and talked with today in Lafayette (see post #179 here).
They are https://www.facebook.com/pages/Irwins-Mattress/184156004978427 or http://www.irwinsmattress.com/ and I talked with the 3rd generation of family ownership Scott and they are making mattresses of all types including memory foam, talalay latex, and innersprings and use better quality materials and construction methods than you will see in typical chain stores and major brands. I guess Baton Rouge isn’t the only local manufacturing happening in Louisiana.
If you are not near any of these and let me know the city you live in I may know of some better retail outlets near you.
NOTE: There is an updated Baton Rouge list in post #191 here.
