Hi jrbrtsn03,
Welcome to the site 
Hopefully you’ve had the chance to read the mattress shopping tutorial here which includes all the basic information, steps, and guidelines that can help you make the best possible choice … and perhaps more importantly know how and why to avoid the worst ones.
There is also more about the most important parts of the “value” of a mattress purchase in post #13 here which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists (based on all the parts of your personal value equation that are most important to you).
The better options and possibilities I’m aware of in and around the Hendersonville/Asheville areas (subject to making sure that any mattress you are considering meets the quality/value guidelines I linked) are listed in post #4 here. If you aren’t close to any of these then if you let me know your city or zip code I’d be happy to link you to any forum lists that are closer to you.
As you mentioned they are one of the members of this site which means I think very highly of them and I believe that they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency.
There is more about the different ways to choose a suitable mattress (either locally or online) that is the best “match” for you in terms of comfort and PPP in post #2 here that can help you assess and minimize the risks and uncertainty of making a choice that doesn’t turn out as well as you hoped for once you actually sleep on your mattress.
When you can’t test a mattress in person (or if you can and you are still uncertain) then the most reliable source of guidance is always a more detailed conversation with a knowledgeable and experienced retailer or manufacturer that has your best interests at heart (such as Arizona Premium) who can help “talk you through” the specifics of their mattresses and the options they have available that may be the best “match” for you based on the information you provide them, any local testing you have done or mattresses you have slept well on and liked that they are familiar with, any special considerations you may have, and the “averages” of other customers that are similar to you. They will know more about helping you to “match” their specific mattress designs or firmness options to different body types, sleeping positions, and preferences or even to other mattresses that they are familiar with than anyone else so that in combination with your own personal testing you can make the “best possible” choice with the highest chance of success.
