How often should you replace your mattress? When your old mattress leaves you feeling tired or achy, it’s time to replace it. The Better Sleep Council recommends trading in your mattress every five to seven years. While it’s not surprising to see this suggestion coming from a trade group, others support this theory, both for comfort and for health reasons. (Mattresses accumulate dead skin cells and perspiration over time, which can attract dust mites and pose health risks.)
If you get a quality mattress with a high coil count, you can expect 10 or 15 years. To prolong the life of any mattress, buy a waterproof, breathable mattress cover, which will help shield the surface from moisture and skin cells. (They start at less than $25.)
Mattress types. The innerspring mattress is no longer the only game in town. Now you have a bewildering array of mattress options to choose from, including memory foam, gel, latex, inflatables and all natural — just to name a few.
Innerspring is the most popular choice and the least expensive; it features tempered steel coils wrapped in layers of cushioning.
Memory foam conforms to the shape of your body, so when you move, the rest of the bed doesn’t shake (good for those bothered by a restless partner).
Gel mattresses combine memory foam with a cooling gel, so the body doesn't get so warm during sleep.
Inflatable air mattresses have an air-filled core that you can adjust to the desired firmness.
All-natural beds trade engineered materials for organic alternatives like wool, cotton and latex.
