Hi TiredDove,
Subject to confirming that any retailer or manufacturer on the list you wish to deal with 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 the Orlando, FL area are listed in post #2 here.
One of the lists in the tutorial that I mentioned in my last reply is the online memory foam list and you can see my comments about Selectabed there. A forum search on Selectabed (you can just click the link) will bring up more comments and feedback about them as well.
