Replace a mattress when it no longer provides acceptable comfort and support, has significant damage, or cannot be kept clean and safe. Age is a useful reminder to inspect it, but there is no universal replacement date. Check the foundation before assuming the mattress is the problem.

- Persistent sagging: A dip remains after the bed is unoccupied and affects how you lie on it.
- Noticeable lumps or unevenness: Padding has shifted or the surface feels inconsistent.
- Damaged or exposed components: A torn cover, broken spring or other damage affects use.
- Weak edges: You feel less secure getting in or out, or the sleep surface feels smaller.
- New noises: Squeaks or creaks can come from the bed frame, foundation or mattress; locate the source.
- Comfort has changed: You no longer like the way the bed feels even after checking your pillow and bedding.
- Sleep is regularly disrupted: The mattress might be one factor, though sleep problems have many possible causes.
- You consistently prefer another sleep surface: Consider differences in pillows, temperature and surroundings too.
- Moisture damage, persistent odor or mold: Assess the cause and the manufacturer’s care instructions; severe damage may require replacement.
- Your needs have changed: A different size, height or feel may now suit your household better.
Morning pain does not prove that a mattress caused it. Persistent pain, numbness, weakness or symptoms following an injury warrant appropriate medical evaluation.
Check the foundation first
Remove the mattress and inspect for broken slats, loose joints, uneven support and a sagging foundation. Check the manufacturer’s requirements for slat spacing, center support and compatible bases; requirements vary. Repairing or replacing an inadequate base may improve support and can matter for warranty eligibility.
What can you try before replacing it?
Follow your mattress maker’s instructions for head-to-foot rotation. Do not flip a one-sided mattress unless the manufacturer says to.
A topper may add cushioning to a sound mattress, but it cannot repair a collapsed support system or reliably level a deep sag.
Worn pillows and an unsuitable pillow height can affect comfort. Make one change at a time so you can evaluate it.
Follow the label for cleaning and protect the mattress from future spills. Avoid soaking materials that cannot dry thoroughly.
Check the warranty before you buy
Warranty length is not a promise of comfort or a predicted lifespan. Many warranties distinguish covered defects from normal softening and use a specific method and depth for measuring impressions. Read your model’s terms and keep the receipt, law tag and photos. This Purple/Intellibed example illustrates why the specific policy matters; other brands differ.
How to choose a replacement
Start with size, budget and the feel you prefer. Spend time in your usual sleeping positions, and compare both pressure relief and ease of movement. Ask about the exact model’s delivery, trial, exchange and return terms before ordering; bedding and bases may have different rules.

Frequently asked questions
Must I replace a mattress after eight years?
No. Use age as a prompt to inspect it, not a deadline. Construction, care and use vary.
Can a topper fix a sag?
It can change the surface feel but cannot restore a failed core or foundation.
Will a warranty cover a dip?
Possibly, if it meets your policy’s conditions. Follow the brand’s measuring and claims instructions.
Does heavier use always mean a predictable reduction in lifespan?
No reliable universal formula applies. Construction, use, foundation and maintenance all influence wear.
