Hi MattressMatt,
The first place to start your research and “reset” the way you may be looking for a mattress is post #1 here which has all the basic information, steps, and guidelines that can help you make the best possible choices … and avoid the worst ones (including the Simmons Comforpedic lineup). It’s probably best to put the Comforpedic out of your mind completely because you are unlikely to be able to find out the specifics of all the layers inside it (which means I would avoid it ) and the only way to find something comparable is based on subjective “feel” and your own side by side testing but “showroom feel” won’t tell you anything about the quality or durability of either mattress. In most cases … the time you spend testing major brand mattresses or time spent in mainstream stores is mostly wasted unless you are just curious about how they feel without regard to quality or how they may compare to other mattresses because they don’t provide enough information about their mattresses to make meaningful comparisons or make an informed buying decision.
Some of the better options and possibilities I’m aware of in the Atlanta / Decatur area are listed in post #2 here.
