Hi goober07,
There is more about the different ways that one mattress can “match” or approximate another mattress in post #9 here.
The specs you listed for the Comforpedic Renewed Energy are probably not accurate and are also very incomplete but even if they were accurate and complete (including the quality and firmness of each layer which is missing) the Comforpedic Renewed Energy has a completely different design and materials than either the 12" Supreme or the 13" Gel memory foam mattress so it’s not likely that either one would be a “match”. In cases where the mattresses are so different then the only way to know how closely one compares to another for you would be based on personal side by side testing. If one of the staff at Dreamfoam is familiar with the Renewed Energy and has specifically compared it to their mattresses then they may be able to share their impressions of how they compare but I personally don’t have any personal experience with either of them and it’s not possible to compare them based on specs … especially when they are very imcomplete.
Having said that … Dreamfoam does say that the 12" Supreme compares to the Tempurpedic Cloud Supreme and that the 13" Gel memory foam mattress compares to the Tempurpedic Cloud Luxe in terms of firmness (not necessarily “feel” or response rate or temperature sensitivity which can vary widely with different types of memory foam) so if you were to test both of these mattresses (they are fairly widely available) then you would have some sense of the relative softness/firmness of each of them.
I would definitely make sure you talk with them on the phone (see post #2 here).
