How Often Should You Change Your Mattress? | Replacement Guide Australia

Your mattress is more than just a place to sleep — it’s the foundation of how well you rest, recover and wake up feeling ready for the day. Over time, even high-quality mattresses wear down, which can affect comfort, support and hygiene.

Replacing your mattress when the time is right can help improve your sleep, protect your health and give you the best chance at a restful sleep.*

In this guide, we’ll cover average mattress lifespan, key replacement signs and practical care tips that’ll help you sleep better for years to come.

Key takeaways

• Most mattresses last 7–10 years depending on materials and how you use them.
• You may need to replace it sooner if you notice sagging, wake up in pain or struggle to sleep.
• Look for lumps, sagging, noise and worsening allergies as replacement signs.
• A quality mattress supports your spine properly and helps improve sleep quality.*
• Rotating your mattress and using a quality bed base can extend its lifespan by 2–3 years.

How long does a mattress last on average?

Most people don’t think about replacing their mattress until something feels wrong. Mattress durability comes down to two main factors: the density of the foam and the strength of the internal springs.

Memory foam, spring and hybrid mattresses

• Latex: 10+ years. Natural latex is extremely resilient, though comfort layers may compress over time.
• Memory foam: 7–9 years. Offers pressure relief but can soften or sag, especially in warmer climates.
• Innerspring: 6–8 years. Coils lose support as internal components wear.
• Hybrid: 8–10 years. Combines foam and springs for balanced durability.

Check for dips, uneven surfaces or sagging every few months. If you're thinking about changing sizes, read our guide to Australian mattress sizes to ensure the best fit.

What are the signs it’s time to replace your mattress?

Physical wear

Visible dips, sagging or uneven surfaces can throw your spine out of alignment. Springs that creak or squeak are often a sign of internal wear.

Sleep and comfort issues

If you wake up sore, stiff or toss and turn, your mattress may no longer be supporting you properly. Poor sleep quality can contribute to fatigue, irritability and chronic pain.*

Bed hygiene concerns

Mattresses trap sweat, dust, dead skin cells and allergens. Over time, buildup can worsen allergies or asthma.*

Upgrading your mattress is also a good time to check your bed frame. Good base support improves airflow, comfort and longevity.

How to extend the lifespan of your mattress

Rotate and flip regularly

Rotate your mattress every 3–6 months to prevent uneven wear. Some mattresses are also flippable.

Use protectors and proper support

Mattress protectors and toppers shield against spills, dust and allergens.

Pair your mattress with a supportive bed frame to improve airflow and reduce moisture damage.

Clean it occasionally

Occasional vacuuming or professional cleaning removes dust mites and allergens.

Replacing children’s and guest mattresses

Children’s mattresses

• Growth changes: Replace every 6–8 years as support needs evolve.
• Physical wear: Play and jumping accelerate wear.
• Hygiene: Stains and odours are signs it’s time for replacement.

Guest beds

• Dust and allergens: Even unused mattresses collect debris.
• The comfort test: If springs are felt or support is weak, replace it.

What to do with your old mattress

• Council pickup: Check local hard rubbish collection.
• Mattress recycling: Many programs recycle up to 75% of materials.
• Donation: Charities accept mattresses in good condition.
