Many people keep a mattress far longer than they should — often because it still “looks fine”. In reality, a mattress can quietly lose support long before it looks worn.
At The Sleep Shop, we regularly meet customers who are surprised to learn their mattress is the root cause of poor sleep, aches, and stiffness.
Here’s how often you should replace a mattress, the warning signs to watch for, and when cleaning and protectors are no longer enough.
How Long Should a Mattress Last?
As a general guideline:
-
7–10 years is the typical lifespan
-
Heavier use, body weight, and materials can shorten this
-
Support usually fails before comfort does
If your mattress is older than 8 years, it’s worth reviewing how well it’s actually supporting you.
Signs Your Mattress Needs Replacing
Common warning signs include:
-
Waking with back, hip, or shoulder pain
-
Sagging or dipping areas
-
Feeling tired even after a full night’s sleep
-
Increased tossing and turning
-
Pain that improves as the day goes on
These are signs of support breakdown, not just surface wear.
Is Cleaning Enough?
Cleaning can improve hygiene, but it cannot fix:
-
Sagging springs
-
Loss of spinal alignment
-
Internal foam breakdown
We explain proper mattress care — and when cleaning isn’t enough — in our full guide on how to clean a mattress properly:

Don’t Forget Your Pillow
An old pillow can make a new mattress feel uncomfortable. Pillows often wear out faster and absorb more moisture.
If you’ve noticed yellow staining, this is usually caused by sweat and body oils over time. We explain this in detail in our guide on why pillows turn yellow and when it’s time to replace yours:
