Hi ceasar2k6,
When you can’t test a mattress in person … the best source of guidance for comfort choices is a more detailed phone conversation with the manufacturer themselves who will know more about their own mattresses than anyone else and can help “talk you through” the options they have available that have the best chance of “matching” different body types, sleeping styles, and preferences based on the “averages” of their customers that are similar to you (see mattress firmness/comfort levels in post #2 here).
