Hi Zuccheto,
Unfortunately … there is a real lack of independent manufacturers in or near New Orleans.
There is a local manufacturer in Layayette however and several more in Baton Rouge that are included in Post #10 here.
The fact that you liked the iComfort revolution indicates that you like soft mattresses 
… and that perhaps you are a side sleeper. It could also mean that you may be sensitive to pressure issues in a mattress … either in your hips or shoulders. Its probably a good thing that you didn’t end up buying this as 5 3/4" of soft foam on top of a mattress is usually a recipe for body impressions and possible back issues.
Some of the better possibilities in the New Orleans area are in post #4 here.
In general … a latex comfort layer with the right thickness and softness for a specific person can be as pressure relieving as memory foam however it is cooler, much more durable, and also more supportive. Both latex and memory foam are also similar in their ability to reduce motion between partners with perhaps a slight edge here going to memory foam.
