Mattress wear develops gradually, so it is not always obvious when a replacement is needed. Age matters, but comfort, support and visible condition are more useful signals.
How long does a mattress last?
Seven to ten years is often used as a general assessment window, not a fixed expiry date. Quality, body weight, bed-base support and maintenance affect lifespan. A mattress may need replacing sooner or remain comfortable longer.
Signs of wear
Look for permanent dips, uneven surfaces, damaged upholstery or springs that can be felt through the comfort layers. If you wake uncomfortable and the mattress feels noticeably better elsewhere, inspect your current bed and base.
Check the bed base
A damaged or unsuitable base can contribute to sagging or noise. Before replacing the mattress, make sure the frame or divan is sturdy and compatible. A new mattress on a failing base may not perform as intended.
Care for your mattress
Use a suitable protector, keep the room ventilated and follow the manufacturer's rotation instructions. Only flip a mattress if it is designed to be double-sided. Avoid standing or jumping on the mattress.
Choose a replacement wisely
Think about what you disliked about the old mattress. If it felt too hard, consider additional cushioning; if it lacked support, review firmness and construction. Compare pocket-sprung, memory foam and hybrid options in the correct size.
Frequently asked questions

Does a sagging mattress need replacing?
Significant permanent sagging may indicate wear; inspect the base too.
Can a new mattress cure back pain?
