As we age, our bodies tolerate less pressure. And so do our mattresses. Combine an aging body with an aged mattress, and you have a recipe for bad rest and rough days. Consumer groups suggest that we buy mattresses every five to seven years. But knowing when to replace a mattress on your bed is best determined by your physical condition and disposition in the morning. If you wake up feeling stiff in Louisville, Ohio, still sleepy in Massillon, Ohio, or noticeably grumpy in North Canton, Ohio, you likely need a new mattress. And Mattress Showcase in Canton, Ohio is the local mattress store to turn to.
