Many mattresses last around 7 to 10 years, with latex and good hybrids often lasting longer and cheaper foam sooner. Replace yours when it sags, you wake stiff or sore, you sleep better elsewhere, or allergies get worse. Rotating regularly and using a protector extend its life; deep sagging within the warranty period may be a valid claim.
Mattresses wear out slowly, so the signs are easy to miss.

| Type | Typical lifespan |
|---|---|
| Innerspring | 5 to 8 years |

Common questions
Can a topper fix an old mattress?
A topper can change the feel of a firm mattress but cannot fix sagging or a failing support core.
Should I flip my mattress?
Only if it is designed to be flipped. Most modern mattresses should be rotated head to foot instead.
Does a warranty cover sagging?
Many cover indentations beyond a stated depth on a proper foundation. Check the terms.
