The average mattress lifespan#
Most mattress manufacturers recommend replacing your mattress every 7–10 years. However, this is a general guideline, the actual lifespan varies considerably depending on the type of mattress, its quality, how you use it and whether you care for it properly.
- Memory foam: 7–10 years
- Hybrid: 7–10 years
- Pocket sprung: 8–12 years (springs are durable, but fillings compress)
- Natural latex: 15–20 years (most durable type)
- Open-coil spring: 5–7 years (cheapest and least durable)
Signs your mattress needs replacing#
Rather than going solely by age, watch out for these signs that your mattress is past its best:
- Visible sagging or body impressions: A dip of more than 3–4 cm is a clear sign the mattress is no longer supporting you properly.
- You wake up with pain: If you regularly wake with a stiff back, aching hips or sore shoulders and the pain eases during the day, your mattress is likely the culprit.
- You sleep better elsewhere: If you consistently sleep better in a hotel or at a friend's house, it's a strong indicator your mattress has given up.
- Increased noise: Creaking or squeaking from the springs indicates they're wearing out.
- You can feel the springs: If you can feel individual springs through the comfort layers, the mattress is done.
- Allergy flare-ups: Old mattresses accumulate dust mites, dead skin cells and mould, which can trigger allergies and asthma.
When mattresses wear out faster#
Several factors accelerate wear:
- Not using a mattress protector (moisture and sweat degrade foam)
- Never rotating the mattress (one-sided wear)
- Heavier sleepers (more pressure per square inch)
- Children jumping on the bed
- Sleeping with pets
How to extend your mattress's life#
- Use a quality mattress protector from day one
- Rotate your mattress 180° every 3–6 months (most modern mattresses are one-sided, so you don't need to flip them)
- Ensure it's on a suitable base, a sagging or broken bed frame will shorten mattress life significantly
- Air it out regularly by folding back the duvet for a few hours
- Clean spills immediately and use a breathable protector
Is it worth repairing a mattress?#
In almost all cases, no. Mattress fillings and foams cannot be meaningfully repaired once they've compressed. A mattress topper can temporarily mask sagging, but it does nothing to restore proper support. If your mattress is showing signs of significant wear, investing in a new one is the better long-term choice, especially given the impact on your sleep quality and physical health.
What the warranties in our catalogue tell you#
A maker's warranty is the most honest lifespan estimate you will get, because they pay if it is wrong. Here is what the three brands we score commit to.
| Brand | Warranty | Trial | What it implies |
|---|---|---|---|
| The Foam People | Varies by model | None | Priced for 5–8 years of service; replace, do not restore |
| Luxe Mattresses | 10 years | 100 nights | Built for a decade; sag depth clause applies |
| Emma | 10 years | 200 nights | Built for a decade; sag depth clause applies |
A 10-year warranty covers manufacturing faults and sag beyond a stated depth (usually 2.5cm), not gradual softening. So a well-made mattress lasts its warranty in structure, but its comfort life is nearer seven or eight years for a heavier sleeper. Our durability guide looks at the cost-per-year maths.
Frequently asked questions#
How often should you replace a mattress?#
Every seven to ten years for a good-quality mattress, five to seven for a budget one, sooner if you wake stiff, see a visible dip of 2–3cm or more, or sleep noticeably better elsewhere. The date matters less than those signs.
Which mattress type lasts longest?#
Natural latex (12–15 years) and dense, well-made pocket-sprung hybrids (8–12) last longest. Low-density memory foam and open-coil springs wear fastest, often under six years. Density and spring gauge matter more than type.
Does body weight affect how long a mattress lasts?#
Substantially. Every material softens faster under more load. Someone over 16 stone should expect two to three years less from the same mattress than someone under 11 stone, and should buy firmer and denser to compensate.
Can you make a mattress last longer?#
Rotate it head-to-foot every three months in the first year and twice a year after, use a protector, keep it on a sound base, and let it air. None of this stops wear; it stops premature, uneven wear.
