Quick answer: Most mattresses should be replaced every six to eight years, though this varies by type. Memory foam typically lasts eight to ten years, pocket-sprung mattresses around seven to eight years, and natural latex can last fifteen years or more. Age is only a guide though. Sagging, lumps, or waking up with aches are signs it is time regardless of how old the mattress is.
Most of us can say roughly how old our car, phone, or washing machine is, but a mattress tends to be a shrug and a rough guess. Since it plays such a direct role in sleep quality and physical comfort, it is worth knowing both the general guidelines and the specific signs that yours needs replacing.
The General Rule: Six to Eight Years
Sleep experts and mattress manufacturers commonly recommend replacing a mattress every six to eight years. A 2026 UK survey of 2,000 adults found the average mattress in use was 6.4 years old, with around a quarter of respondents sleeping on one that was nine years or older. This suggests many people are keeping mattresses well past the point where they are still offering proper support.
Lifespan by Mattress Type
Not all mattresses age at the same rate, since the materials inside behave differently over time.
Memory Foam
A good-quality memory foam mattress typically lasts eight to ten years, sometimes longer, depending on the density of the foam and how often it is used.
Spring and Pocket-Sprung
Traditional spring or pocket-sprung mattresses generally need replacing every seven to eight years. The springs gradually lose tension, which leads to dips and reduced support, and this tends to happen faster than with foam.
Hybrid
Hybrid mattresses combine springs with layers of foam or latex, and typically last around eight years, sometimes longer where the spring unit is high quality, since the springs carry most of the structural load.
Natural Latex
Natural latex is the most durable common material, often lasting fifteen to twenty-five years with proper care.
Synthetic Latex
Synthetic or blended latex softens faster than natural latex and usually needs replacing every five to ten years.
Signs Your Mattress Needs Replacing
Age is a useful guide, but these physical signs matter more than the number of years on the clock.
- Visible sagging or dips, particularly where you usually sleep
- Lumps or uneven areas you can feel through the fabric
- Waking up with back, neck, or joint stiffness that eases once you are up and moving
- Sleeping noticeably better in a different bed, such as on holiday or at a friend’s house
- Increased allergy symptoms, which can point to a buildup of dust mites and skin cells inside older mattresses
- Audible springs, creaking, or a spring poking through the fabric
If you notice two or more of these, it is worth replacing the mattress even if it has not reached the typical age guideline yet.
Does Body Weight Affect Mattress Lifespan?
Yes. Heavier use puts more strain on the internal materials, whether foam or springs, and can shorten the expected lifespan by a couple of years compared to the averages above. If you are a heavier sleeper, or two people share a mattress designed for lighter use, checking for sagging a little earlier than the typical replacement point is a sensible habit.
How to Extend Your Mattress’s Lifespan
- Use a mattress protector to guard against sweat, skin cells, and spills, all of which degrade the comfort layers over time.
- Rotate the mattress regularly, roughly every three to six months, so wear spreads evenly rather than concentrating in one spot.
- Check the manufacturer’s guidance on whether your mattress should be flipped as well as rotated, since some modern designs are one-sided.
- Make sure your bed frame or base properly supports the mattress. A sagging set of slats or a worn divan base can pull an otherwise good mattress out of shape.
- Keep the room reasonably ventilated to reduce moisture buildup inside the mattress over time.
What About Bed Frames, Pillows, and Duvets?
Since you are already thinking about mattress age, it is worth checking what else in the bed is due for a refresh. UK survey data suggests bed frames average around 9.3 years old, with a substantial share over 11 years old. Pillows average 3.6 years and are generally recommended for replacement every one to two years, since they lose shape and can harbour dust mites well before they visibly wear out. A sagging bed frame or worn slats can undermine even a good mattress, so it is worth checking the base at the same time you assess the mattress itself.
Disposing of an Old Mattress in the UK
Mattresses cannot go in general household waste collections in most UK council areas. Your options typically include booking a bulky waste collection through your local council, usually for a fee, taking it to a household waste recycling centre yourself, or asking the retailer to take the old one away when a new mattress is delivered, which many offer as part of the service. Some charities will also collect mattresses in good condition for reuse, though most require them to meet fire safety labelling requirements and be free of visible damage or stains.

Frequently Asked Questions
How do I know if my mattress needs replacing?
Look for visible sagging or lumps, morning stiffness that improves once you are up, and sleeping better away from home. Any of these matter more than the mattress’s exact age.
How long does a memory foam mattress last?
Typically eight to ten years, depending on the density of the foam and how heavily it is used.
Does mattress type affect how often I should replace it?
Yes. Natural latex lasts the longest, often fifteen years or more, while spring and synthetic latex mattresses tend to need replacing sooner, usually within five to eight years.
How do I dispose of an old mattress in the UK?
Book a bulky waste collection with your local council, take it to a household waste recycling centre, or ask your new mattress retailer to remove the old one on delivery.
Should I replace my mattress and bed frame at the same time?
Not necessarily, but check the frame’s condition when you replace the mattress. A worn or sagging base can shorten the life of a brand new mattress considerably.
Final Thoughts
Six to eight years is a reasonable starting point for most mattresses, but the physical signs, sagging, lumps, and how you feel in the morning, are a more reliable guide than age alone. Using a protector, rotating regularly, and checking your bed frame’s condition will all help you get the most out of a mattress before it is time to replace it.
