Replace a Mattress Every 7–8 Years? Explained

Should you replace your mattress every 7–8 years?

Not automatically. Seven to eight years is a rule of thumb. It reminds you to check your mattress. It is not a use-by date.

Replace a mattress when it stops doing its job. That means it sags, has lumps, creaks, or no longer feels even across the surface. A mattress in good condition can last longer. A cheap or heavily used one may wear out sooner.

Where does the number come from?

The advice comes from the UK bed industry. The National Bed Federation (NBF) is the trade body for UK bed makers. In 1995 it set up The Sleep Council to give advice to the public.

The Sleep Council’s first message was to replace beds every ten years. The NBF says many people then kept a bed for about 20 years. Later, the advice shortened to every seven to eight years.

The usual reason given is wear. Over seven to eight years, a mattress is used for about 20,000 hours. That is roughly eight hours a night, every night.

What the number does not mean

• It is not a law. No UK rule says a mattress must be replaced at a set age.
• It is not a test result. We did not find a published study that sets eight years as the limit.
• It is not the same for every mattress. Foam, springs and latex wear at different rates. How much the mattress is used matters too.
• It is not neutral. The advice comes from a trade body whose members sell beds. That does not make it wrong, but it is worth knowing.

Is this the latest figure?

Yes. Seven to eight years is still the industry’s advice. What people actually do has changed, though.

NBF research found the average replacement cycle fell from 7.9 years in 2016 to 6.9 years in 2019. But the NBF’s October 2025 report says mattress disposals were 27% lower in 2023 than in 2020. It suggests people may now be keeping mattresses longer, possibly because of money pressures.

How do you know when to replace your mattress?

Check the mattress, not the calendar:

• Can you see a dip or body impression that does not recover?
• Do you feel springs, lumps or hollows?
• Does it creak or feel uneven?
• Has a stain, spill or damage made it unhygienic?
• Has the base underneath been checked? A worn base can make a mattress feel worse.
