Hi steeve,
Welcome to the Mattress Forum! 
That’s the great thing about having the site is you can always refer back to it. I suggest reading through things as you would a good book and not trying to memorize things.
As I think you are aware, Spindle is a member of this site which means that I think very highly of them and that I believe that they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency. I would definitely spend some time with them on the phone before making any final decisions should you wish to purchase from them.
Subject to first confirming that any retailer or manufacturer on the list that you wish to visit is completely transparent (see this article ) and to making sure that any mattress you are considering meets the quality/value guidelines here … the better options or possibilities I’m aware of in and around Chattanooga area in post #2 here and some of them at last check did offer latex.
Please let me know if you have any questions should you visit any of your local retailers.
