This is a question often asked in the process of searching for a new sleep system. The truth is that firmer mattresses aren't necessarily better for you. A mattress that is too firm does not support the body evenly, tending only to support the body's heaviest parts. A mattress that is too soft will sag and prevent the spine from maintaining its' proper alignment. Neither situation allows your muscles to rest, as they must work through the night to find a comfortable position and maintain correct posture.

Many people, especially men, think a mattress has to feel like a park bench to get that great support they ultimately desire. The truth is that "firm" is a support term, not a "comfort" term. So instead of a firm mattress, you need a firm mattress "core" with some degree of softer padding on the surface to eliminate pressure points and circulatory problems.
