by Quick answer: Most mattresses should be replaced every 7 to 10 years, but it depends on type: innersprings often last 5–7 years, memory foam and hybrids 7–10, and natural latex 12–15. Watch the warning signs, like sagging, morning aches, or sleeping better elsewhere, not just the calendar.

Mattress Replacement Timing Explained
The widely cited rule is every 7 to 10 years, but that's an average, not a deadline. Even a mattress that still feels okay may have degraded enough internally that it no longer supports you the way it once did. The smarter approach is to start checking around the 7-year mark and let the physical signs decide.
Lifespan varies a lot by construction, so the right number for you depends on what you sleep on and how hard you use it.
Key Points
| Factor | What to know |
|---|---|
| Innerspring | Typically 5–7 years as coils lose tension and sag. |
| Memory foam & hybrid | Generally 7–10 years. |
| Natural latex | Most durable, often 12–15 years or more. |
| Body weight | Over ~230 lbs compresses materials faster, closer to 5–7 years. |
Details & What to Look For
Trust the signs over the calendar. The clearest ones: visible sagging or a permanent body imprint (a dip of about 1.5" or more usually means it has failed), waking with back, neck or shoulder pain, sleeping better at hotels, more tossing and turning, and worsening morning allergies from accumulated dust and dander.
You can extend life with maintenance: rotate about every three months for even wear, and spot-clean and vacuum a couple of times a year. Note that most modern mattresses are one-sided and should not be flipped.
The Saatva Angle
When it is time to replace, durability is worth paying attention to. The Saatva Classic is a coil-based innerspring built with triple-tempered recycled steel coils and backed by a lifetime warranty, which signals confidence in how it holds up. A 365-night home trial also lets you confirm it suits you before you commit. It's one durable, well-supported option to weigh when your current bed reaches the end of its life.
Bottom Line
Plan to evaluate around year 7, adjust for your mattress type and body weight, and replace when the warning signs show up rather than waiting for a date. Maintenance buys you time, but it doesn't make a failed mattress new again.
Bottom line: Replace most mattresses every 7–10 years, but let sagging and morning pain, not the calendar, make the final call.
