Hi Mojoesimpson,
The first place I would start your research is the tutorial post here which has all the basic information, steps, and guidelines that can help you make the best choices … and avoid the worst ones.
I’m not sure which list you mean but reviews are among the worst ways to choose a mattress (see post #13 here). Using reviews to choose a mattress would be much like trying to buy healthy food based on reviews about how different types of foods taste to people that know very little about nutrition (if you listened to my own personal taste preference you would eat nothing but ice cream … but it would be good ice cream :)).
There are too many unknowns, variables, and personal preferences for anyone to make a mattress choice for someone else out of all the many thousands of mattresses that are available. I’m happy to help you with “how” to choose but “what” to choose is up to each person and the parts of their personal value equation that are most important to them.
The better options and possibilities I’m aware of in the Dallas / Ft Worth area are listed in post #4 here and they include manufacturers who still make some high quality two sided mattresses.
