Hi sgt,
I split your post into a new topic so your “other” questions don’t get mixed in with another member’s topic.
You can see my reply to this in the original topic in post #2 here.
Arizona Premium/Mattresses.net is one of the members of this site which means that I think very highly of them and I believe they compete well with the best in the industry in terms of their quality, value, service, and transparency. They are certainly a “value leader” for latex mattresses.
A forum search on “mattresses.net” or on “Arizona Premium” (you can just click the links) will bring up many more comments and more information and feedback about them.
I would also be very cautious about using mattress reviews (positive or negative) as a reliable source of mattress research or information and in many cases they can be much more misleading than helpful (see post #13 here).
There is more about the different ways to choose a mattress that is most suitable for you (either online or local) and how to minimize the risks involved in each of them in post #2 here.
Post #13 here also has more about the most important parts of the “value” of a mattress purchase that can help you make more meaningful comparisons between mattresses.
The better options or possibilities I’m aware of in the Raleigh/Durham, NC area (subject to the “value” guidelines I linked) are listed in post #6 here.
