Hi BillT83,
I’m glad you found us … and thanks for the kind words 
You’ve probably read these already but you can read more about Bedinabox and the claims they make in post #2 here and as you mentioned … I also believe that mattress reviews can be very misleading (see post #13 here).
There are too many unknowns, variables, and personal preferences involved for anyone to recommend a specific mattress for someone else based on “theory at a distance” or height and weight information but the tutorial post here has all the basic information, steps, and guidelines that can help with “how” to make the best possible choice … and avoid the worst ones.
It also includes some links to some of the better online choices I’m aware of for those who are comfortable purchasing online and if you let me know your city or zip code I’d also be happy to let you know of any of the better local options or possibilities I’m aware of.
I’m looking forward to finding out what you end up choosing … and of course any questions or comments you may have along the way.
Phoenix
