Many patients ask us advice on mattresses. Questions like "When should we replace our old one?" and "Which mattress should we get?" are questions we hear weekly at our offices.
Most mattresses have about 10 useable years when you buy them. Pillows are good anywhere from 18 months to 2 years. The best answer for "When should we replace our old mattress?" is when you wake up feeling worse than when you went to bed. Sleep is supposed to restore you. You and your body should feel better after a good night sleep.
You spend anywhere from 25-33% of your life asleep in bed. That means that in the next 10 years, you will spend 3 of those years on your mattress (except for that weekend you had to sleep on your cousins futon and had to come in to see your favorite chiropractors right after). With this in mind, it makes sense to invest in a good bed.
