Your mattress is one of the most-used items in your home — yet it often gets ignored until it starts to cause problems. Unlike your phone or car, there’s no clear reminder to upgrade, so many people keep sleeping on worn-out mattresses long past their prime.
So how long should a mattress really last, and how can you tell when it’s time for a replacement? Let’s break it down.
1. The Average Mattress Lifespan
A quality mattress typically lasts 8 to 10 years, depending on:
-
The type of mattress
-
The quality of its materials
-
How often it’s used
-
How well it’s maintained
Lower-quality foam mattresses can start to break down within five to six years, losing shape and support. In contrast, a premium hybrid mattress — like those from Sleep Republic — can maintain comfort and structure for well over a decade, thanks to its durable spring and foam combination.
2. Signs Your Mattress Needs Replacing
Even the best mattresses wear out over time. Here are some clear signs it’s time for an upgrade:
-
Visible sagging or deep body impressions that don’t bounce back
-
Lumps or dips that make the surface uneven
-
Squeaky or weakened springs
-
New or worsening back and joint pain
-
Increased partner disturbance from reduced motion isolation
If you’re waking up stiff, sore, or still tired after a full night’s rest, your mattress may no longer be giving your spine the support it needs.
3. The Hygiene Factor
Even with regular cleaning and a mattress protector, all mattresses collect dust, sweat, and allergens over time. These can trigger allergies and asthma symptoms, particularly if your mattress is several years old.
To keep your mattress cleaner for longer, use a breathable Mattress Protector and wash your bedding regularly. When odours linger or allergies worsen, it’s usually a sign it’s time to replace your mattress altogether.
4. When Life Changes, So Should Your Mattress
Our sleep needs evolve over time. You might have gained or lost weight, developed back or joint issues, or simply changed your preferred sleep position. If your mattress no longer feels comfortable or supportive, upgrading is one of the easiest ways to improve your overall wellbeing.
For enhanced support and pressure relief, the Sleep Republic Hybrid Mattress uses high-definition pocket springs, gel-infused memory foam, and natural latex for breathability, alignment, and all-night comfort.
5. Invest in Long-Term Comfort
At Sleep Republic, our hybrid mattresses are built for endurance. With a 12-year warranty and a 150-night risk-free trial, you can rest easy knowing your sleep investment will stand the test of time.
For the ultimate in luxury and longevity, the SR Luxe Mattress features multi-layered comfort zones and reinforced edge support — ideal for sleepers who want extra durability and refinement.
Sleep Better for Years to Come
If your mattress is more than eight years old, showing signs of wear, or no longer helping you wake up refreshed, it’s time for a change. You spend about one-third of your life in bed — make sure it’s on a mattress that supports your comfort, health, and future.
Frequently Asked Questions
How often should you replace your mattress?
Most people should replace their mattress every 8–10 years, or sooner if they experience sagging, discomfort, or poor sleep quality.
Do hybrid mattresses last longer?
Yes. Hybrid mattresses with pocket springs and high-quality foam layers typically last longer than all-foam models due to better structural integrity and airflow.
What voids a mattress warranty?
Improper use — such as placing the mattress on an uneven or unsupportive base — can void the warranty. Always pair your mattress with a suitable Bed Base for longevity.
