Hi augeydogy,
When you are considering an online purchase … the most effective source of advice and guidance will always come from a more detailed conversation with a knowledgeable and experienced manufacturer (which SleepEz is). They know more about the details of their mattresses and the options they provide than anyone and are much better at helping their customers make the most suitable layer choices than anyone else (including me) based on the more detailed information you provide them on a phone call and on their experience and the “averages” of their customers that may be similar to you (see mattress firmness/comfort levels in post #2 here).
I would avoid emails when it comes to something as important as choosing a mattress because there can be too many “it depends” in the answers to questions such as the ones you asked. Emails can’t provide the more nuanced information that takes more specific questions (that you may not know to ask) or more rapid back and forth “interactive” conversations that making a mattress choice will often require. You can cover more ground in a half hour conversation than you can in days or weeks of back and forth emails.
