Good quality preferably latex comfort firm support options
Hi Sharon3.
Welcome to our Mattress Forum. 
Our Trusted Members are thoroughly vetted by our site and meet our transparency and quality/durability standards. We don’t currently have any in Tennessee, but I did some research and found these companies:
Brothers Bedding
Southerland
Well Tucked
Bedr Mattress
I haven’t personally vetted them, but at first glance, they appear to be solid contenders. You may also want to read our article on how to identify a great retailer so that you’re feeling better prepared for in-person testing.
