Most mattresses should be replaced every seven to ten years. Replace sooner if you see sagging deeper than an inch, wake up stiff or sore, notice lumps or noise, or consistently sleep better away from home. A protector and regular rotation extend a mattress’s life.
A mattress wears out gradually, so it is easy to keep one years past its prime without noticing. Here is when to replace it and the signs to watch for. To choose the next one, see our mattress buying guide.
The general timeline
Quality mattresses last seven to ten years. Latex can last longer; cheap foam wears out sooner. Age alone is not the rule, though, so check for the signs below.
Signs it is time to replace
- Visible sagging or body impressions deeper than about an inch.
- Morning aches that ease as the day goes on.
- Lumps, noise or a failing edge.
- You sleep better in hotels than at home.
- Worsening allergies from years of dust-mite buildup.
How to make a mattress last
Use a washable mattress protector from day one, rotate the mattress head-to-foot every three to six months, and keep it on a supportive base. Clean it a few times a year with our mattress cleaning guide.
Can a topper buy time?
A good topper can extend comfort for a year or two if the support core is still sound, but it cannot fix real sagging. See our topper guide for options.
