When should I replace my mattress?
In short
Consider replacement when support is lost — visible sag, springs felt through the surface, edges collapsing, or sleep pain that improves away from home — especially if the mattress is past typical material lifespan bands (often 6–10 years).
What else should I know?
Age alone is a clue, not a rule. A well-kept latex or pocket unit may outlast a low-density foam model. Check base condition too; a failed base mimics mattress failure.
