Most people are diligent about washing their sheets, but when was the last time you cleaned—or even thought about cleaning—your mattress? While fresh sheets can make your bed feel clean, they only cover up what’s lurking beneath. From dust mites to bacteria, your mattress could be harbouring unseen allergens that affect your sleep and health.
And here’s the real shocker: according to the Sleep Council UK, an old mattress can contain up to 10 million dust mites. If that doesn’t make you reconsider your cleaning routine, nothing will.
Fresh sheets might make your bed feel clean, but dust mites and allergens could still be lurking underneath. The British Bed Federation (BBF) advises regular mattress cleaning to maintain a healthier sleeping environment.
So, how often should you clean or replace your mattress? And if it’s time for a new one, how can you find an affordable, high-quality option? Let’s dive in.

What’s Really Living in Your Mattress?
According to Allergy UK, dust mites are one of the most common indoor allergens, affecting millions of people. Investing in a hypoallergenic mattress protector can significantly reduce allergen exposure.
A mattress may look clean on the surface, but deep inside, it’s a different story. Over time, your mattress can accumulate:
- Dust mites – Tiny creatures that thrive in warm, humid conditions and feed on dead skin.
- Sweat and body oils – Absorbed into the mattress over time, creating the perfect environment for bacteria.
- Mould and mildew – Especially common in damp conditions or older mattresses.
- Bacteria and allergens – Including pet dander, pollen, and even fungi.
The result? Increased allergy symptoms, poor sleep quality, and even potential respiratory issues. If your mattress is more than seven to eight years old, it may be time to replace it.
How Often Should You Replace Your Mattress?
The National Bed Federation (NBF) recommends replacing your mattress every seven to ten years for the best sleep quality and hygiene. However, this depends on factors like wear and tear, hygiene, and material quality.
Signs it’s time to replace your mattress:
✔ You wake up feeling stiff or achy.
✔ Your mattress is visibly sagging or lumpy.
✔ You experience allergies or breathing issues in bed.
✔ Your sleep quality has noticeably declined.
If your mattress has reached the end of its lifespan, consider upgrading to a zip link divan bed for added flexibility—perfect for couples or guest rooms.
Comparison Table: Clean vs. Unclean Mattresses
| Feature | Well-Maintained Mattress | Unclean, Old Mattress |
| Hygiene | Free from dust mites, bacteria, and allergens | Traps dust, mould, and bacteria over time |
| Comfort | Even support and pressure relief | Sagging, lumps, and reduced comfort |
| Health Impact | Supports good sleep and respiratory health | Increases allergy risks and poor sleep |
| Odour | Fresh and neutral-smelling | Can develop musty or unpleasant odours |
| Lifespan | Lasts 7–10 years with proper care | Wears out faster and requires earlier replacement |
A well-maintained mattress can significantly improve your sleep quality, but if your current one is past its prime, consider investing in a next-day delivery bed in the UK for a hassle-free upgrade.
Best Ways to Keep Your Mattress Fresh
If you’re not ready to replace your mattress just yet, here are some easy ways to extend its lifespan and keep it clean:
- Use a mattress protector – This simple addition prevents sweat, dust, and spills from seeping into your mattress.
- Vacuum your mattress regularly – Use an upholstery attachment to remove dust and debris.
- Rotate your mattress every six months – Helps prevent sagging and ensures even wear.
- Air out your mattress – Strip the bedding and let it breathe for a few hours to reduce moisture build-up.
- Deep clean stains and odours – A mix of baking soda and vacuuming can help refresh your mattress.
Top Tip: For a natural refresh, sprinkle baking soda over your mattress, let it sit for 30 minutes, then vacuum. Adding a few drops of lavender essential oil can help neutralise odours and promote relaxation.
Final Thoughts: Sleep Better With a Cleaner Bed
Your mattress plays a bigger role in your health than you might think. While changing your sheets is important, it’s not enough to maintain a hygienic sleeping environment. Regular cleaning, combined with replacing your mattress when necessary, ensures better sleep, improved health, and long-term comfort.
