One way to maintain the life span of a mattress is to make sure it wears evenly over time. A simple trick is to rotate the mattress on a regular basis so that the entire surface gets used, which helps prevent indentations in the overall shape of the mattress. Best time to rotate? Whenever you change the clocks to jump back or forward an hour, or any other twice-a-year event that always comes at the same time.
