Most people should plan to replace a mattress roughly every 7–10 years, but the right timing depends on materials and how it feels to your body. Pay attention to comfort and signs of wear rather than just the calendar.
General time frame
Most sleep and health organizations suggest replacing a mattress about every 6–10 years under normal use. Many brands and retailers narrow this to an average lifespan of around 7–10 years for a quality mattress.
By mattress type
Different constructions wear out at different speeds. Typical ranges are:
- Innerspring: about 5–8 years.
- Foam or hybrid: about 7–10 years.
- Latex: often 10–15 years, sometimes longer if well cared for.
Signs you need a new one
You should replace the mattress sooner than the averages if you notice certain changes. Key signs include:
- Sagging, lumps, or impressions that do not spring back.
- New or worsening aches, stiffness, poor sleep, or allergy symptoms that improve away from your bed.
Factors that shorten or extend life
Heavier body weight, two people sharing a bed, and nightly use will wear a mattress out faster. Using a mattress protector, rotating it every few months (if the manufacturer allows), and keeping it clean can extend its useful life toward the upper end of those ranges.
