Hi Lankynonyankee,
Nashville isn’t the best area in terms of local factory direct manufacturers but there are still some better choices in the general area. Post #7 here includes the better options that I am aware of.
I’m not sure what size you’re looking at for the price reference … but even at a small discount I wouldn’t consider the iComfort to be very good value … even though it is very popular (there are a lot of people who are buying them based on their “showroom feel” rather than on the quality of materials or the value of the mattress).
Hope this helps
Phoenix
