When to Replace Your Mattress: 8 Signs It Is Time
Replace your mattress when it sags or has lumps, when you wake up stiff or sore, or when you sleep better anywhere else. Many mattresses last somewhere around 7 to 10 years, but how it feels and supports you matters more than its age.
Key takeaways
- Visible sagging or lumps are the clearest sign a mattress has worn out.
- Waking stiff or sore, and feeling better after a night elsewhere, point to the mattress.
- Many mattresses last around 7 to 10 years as a rough guide; use it as a prompt, not a rule.
- Rotate it head to foot every three months and use a protector to help it last.
- Check the City of Hamilton's rules before putting an old mattress out.
When should you replace your mattress?
Replace your mattress when it sags or has lumps, when you regularly wake up stiff or sore, or when you sleep better anywhere else. As a rough guide, many mattresses last somewhere around 7 to 10 years, but the age is only a prompt to check. How the mattress looks, sounds and supports you tells you more than the date you bought it.
8 signs it is time for a new mattress
- A dip or sag where you sleep that does not recover, or a slope towards the middle.
- Lumps and soft spots, where the filling has shifted or broken down.
- You wake up stiff or sore, and it eases as the day goes on.
- You sleep better elsewhere, such as in a hotel, a guest bed or on the sofa.
- Noisy springs that creak or ping, or coils you can feel through the top.
- Edges that collapse when you sit on the side of the bed.
- You feel every move your partner makes, more than you used to.
- Stains, smells or more sneezing that cleaning and a protector no longer fix.
How long does a mattress last?
There is no fixed lifespan. Many mattresses last somewhere around 7 to 10 years, but the real number depends on several things:
| Factor | Helps it last | Wears it out sooner |
|---|---|---|
| Base | A solid, supportive base or close slats | A sagging or broken base |
| Care | Rotating it and using a protector | Never turning it; spills soaking in |
| Use | A guest bed used now and then | Two adults every night; children jumping |
| Fit | The right size for the frame | A mattress that bends or hangs over the frame |
How do you check your mattress?
- Strip the bed and look along the surface at eye level for dips and slopes.
- Lay a broom handle or long ruler across the middle; a clear gap underneath shows a sag.
- Press and lie on different areas to feel for lumps, hard spots and springs.
- Sit on each edge to see whether it holds you up.
- Check the base too: a broken slat can make a good mattress feel worn.
How do you make a mattress last longer?
- Use a washable, breathable mattress protector from the first night.
- Rotate it head to foot about every three months, so it wears evenly.
- Keep it on a solid, supportive base that suits the mattress.
- Air it out for a while when you change the sheets.
- Avoid sitting on the same edge every day, and no jumping on the bed.
- Vacuum the top now and then with an upholstery attachment.
What do you do with the old mattress?
In Hamilton, collection rules for mattresses and other bulky items are set by the City and can change, so check the City of Hamilton's page on bulk items and furniture before you put an old mattress out. Wrap it in plastic before you move it to keep your home and car clean.
How do you choose the next one?
Start with the size of your frame, then the feel that suits how you sleep, and lie on it for 10 to 15 minutes before you buy. Our guide to choosing a mattress walks through each step, our thickness guide explains what 30 cm means for your bed and sheets, and if you have a Turkish or European frame, read which mattress fits a Turkish bed.

Frequently asked questions
How long does a mattress last?
As a rough guide, many mattresses last somewhere around 7 to 10 years, but it varies with the materials, the base, the weight on it and how well it is cared for. Treat the age as a prompt to check it. If it sags, feels lumpy or leaves you sore, it is time, whatever its age.
How do I know if my mattress is too old?
Look for a dip where you sleep, lumps or soft spots, springs you can feel or hear, and edges that collapse when you sit. Then think about how you feel: waking stiff or sore, tossing and turning, or sleeping better in a hotel or guest bed are all signs your mattress no longer supports you.
Can a sagging mattress cause back pain?
A mattress that sags can let your spine fall out of line, and many people notice more stiffness when that happens. If your back feels better after a few nights on another bed, the mattress may be part of the problem. For ongoing pain, speak to your doctor or physiotherapist.
How can I make my mattress last longer?
Use a washable mattress protector from day one, rotate the mattress head to foot about every three months, and keep it on a solid, supportive base. Let it air out when you change the sheets, avoid sitting on the same edge every day, and do not let children jump on it.
How do I get rid of an old mattress in Hamilton?
Check the City of Hamilton's guidance on bulk items and furniture before you put a mattress out, as the rules and any limits are set by the City and can change. Wrapping a mattress before you move it keeps it clean and makes it easier to carry.
