How Long Does a Mattress Last?

A practical look at mattress lifespan, wear, support changes and replacement signals.

There is no universal expiration date

Mattress lifespan varies with construction, material quality, sleeper load, use frequency, foundation quality and care. A guest mattress and a primary mattress can age very differently.

Replace based on performance

Persistent sagging, loss of support, visible damage or a meaningful change in comfort can matter more than an arbitrary anniversary.

Protect the basics

Use an appropriate foundation, keep the mattress clean and dry, and follow the manufacturer's rotation and care guidance.
