How Often Should You Replace Your Mattress?

Your mattress plays a bigger role in your health than you might think. After all, you spend about a third of your life sleeping—and the quality of that sleep depends largely on the comfort and support your mattress provides. But how do you know when it’s time to say goodbye to your old bed and invest in a new one?

The Average Lifespan of a Mattress

Most mattresses last 7–10 years. The exact lifespan depends on the type of mattress, the quality of its materials, and how well it’s cared for. Premium mattresses may last longer, while budget models may wear out sooner.

Signs It’s Time for a New Mattress

Even if your mattress is within the average age range, certain warning signs signal it’s time for a replacement:

• Sagging or indents that no longer support your body properly

• Lumps or uneven areas that cause discomfort

• Waking up stiff or sore despite getting enough hours of sleep

• Increased allergy symptoms, which may indicate dust buildup inside the mattress

Why Replacement Matters

Sleeping on a worn-out mattress doesn’t just affect your comfort—it can impact your health. Poor support may lead to back or neck pain, restless nights, or reduced sleep quality. Over time, this can affect your energy levels, mood, and overall well-being.

How to Extend the Life of Your Mattress

While no mattress lasts forever, proper care can maximize its lifespan:

• Use a mattress protector to guard against spills and allergens

• Rotate it regularly (and flip, if designed for double-sided use)

• Keep it on a strong, supportive foundation

Final Thoughts

If your mattress is more than 7 years old—or you’re noticing sagging, lumps, or morning aches—it might be time to upgrade. A new mattress is an investment not just in better sleep, but in your long-term health and comfort.
