But every mattress should be replaced after 15 years at the latest.

In this article, you’ll find out everything you need to know about how often to change a mattress. 👇

How often should you change your mattress?

How long a mattress lasts depends on a few things, like the material, how well you look after it, and how much use it gets.

Here’s the general rundown:

  • Cheap mattresses: With budget models, you’re looking at a change every 5 to 8 years, as they tend to lose support quicker.
  • High-quality mattresses: Better-quality ones can go for 8 to 10 years before needing a swap.
  • Maximum lifespan: Regardless of quality, you should replace your mattress after 10 to 15 years at the latest - just for hygiene’s sake.

But is it enough to just clock the years?

When should you change your mattress?

Even if your mattress hasn’t hit its max age, there are warning signs you shouldn’t ignore:

Dips and lumps

If your mattress has dents, sags, or uneven patches, and you feel like you’re sinking into it every night, the support’s well and truly gone.

Over time, the materials - like foam or springs - wear down, especially in the spots where you sleep most.

This can throw your spine out of whack, making it harder to get comfy and stay that way.

Morning back pain

Are you waking up stiff, achy, or with regular back pain that wasn’t there before?

Your mattress might not be holding you up properly anymore.

A good mattress keeps your spine aligned while you snooze, but when it’s past its prime, it stops doing that job.

If you’re noticing twinges or soreness that linger into the day, it’s a big clue.

Worsening allergies

Sneezing heaps, waking with watery eyes, or feeling stuffed up every morning?

House dust mites could be the culprits - they love to settle into mattresses over the years.

The older it gets, the more these tiny pests build up, along with dead skin and dust.

Changing it could clear the air and ease those symptoms.

Musty smells or stains

Catching a whiff of pongy odours, spotting mouldy patches, or seeing stubborn stains?

Time to haul it to the tip.

These are dead giveaways that moisture isn’t escaping like it should.

Sweat, spills, and dampness get trapped over time, breaking down the materials and making it a breeding ground for mould or mildew - yuck!

How can you extend your mattress’s lifespan?

With the right care, you can stretch out how long your mattress lasts and get the most from it.

Here some tips:

  • Flip and rotate: Every three months, turn or spin your mattress to even out the wear.
  • Use a protector: A mattress protector keeps off dirt, sweat, and stains - and you can just bung it in the wash.
  • Air it out: Making your bed straight after waking? Bad move! Let it breathe by folding back the covers in the morning.
  • Clean the cover: Washable covers should get a 60°C spin every three months to cut down on mites and bacteria.

With these steps, you can keep your mattress comfy and clean for longer, delaying how often you need to change a mattress.

Conclusion – how often should you change a mattress?

A mattress is an investment in your health.

The better you care for it, the longer it’ll serve you well.

But even top-notch care can’t stop natural wear forever.

Aim to change it after 8 to 10 years - or sooner if you spot clear signs it’s knackered.

Your body will thank you!
