When to Replace a Mattress: 3 Signs You Need a New Mattress

Different mattresses have different life spans. In general, you should replace your mattress every seven to ten years. Mattress materials and construction determine the specific longevity of each type of mattress.

• Innerspring: Innerspring mattresses feature metal coils that support layers of cushioning. The coils can be supplemented with a mattress topper, sometimes known as a pillow-top. Expect an innerspring mattress to last six to seven years, at which point you should begin shopping for a new bed.
• Memory foam: The longevity of a memory foam mattress depends on its quality. Low-density foam will show signs of wear in five to six years; a high-density memory foam mattress will last nearly twice as long—around ten years. In the short term, both high-grade and low-grade memory foam can relieve pressure points and address back pain.
• Latex: A natural latex model may be the best mattress for overall longevity, with many lasting upwards of 15 years. Synthetic latex also lasts a long time, usually around ten years.
• Hybrid: A hybrid mattress combines an innerspring core with comfort layers made of latex or memory foam. In most cases, they provide the sleep quality of a full foam mattress—including dampened motion transfer—at a lower price point. In terms of longevity, they last roughly the same length of time as an innerspring mattress. After six to seven years, you may be ready for a new bed.

To determine if your old mattress needs to be replaced, consider how your mattress may be affecting your sleep.

1. 1. Permanent indentations: If you see consistent dips in the sleep surface of your mattress, it may be time to buy a replacement. This is particularly true for innerspring and lower-grade memory foam mattresses.
2. 2. Dust mites: Dust mites are drawn to the dead skin cells that humans shed naturally during sleep. You can combat dust mites by vacuuming or by using a regularly washed mattress protector. For your overall health, if you notice a buildup of pests or allergens, it’s worth considering a replacement mattress.
3. 3. Discomfort: If you find that you are regularly feeling sore and poorly rested, you may have a mattress past its prime. Be aware that other factors—including your sleeping position—can cause discomfort and poor sleep. If you have had the same mattress for more than seven years, though, body pain may be a sign that you need to upgrade.
