How Long Does a Mattress Last? Signs It Is Time to Replace Yours

A mattress is a significant investment, and knowing when to replace it can be tricky. Most mattresses last 7–10 years, but the right answer depends on the materials, construction, and how well you have cared for it. This guide covers how long different mattress types last, the visible signs of wear, comfort and support changes, hygiene considerations, and situations where replacement may not actually be necessary. For warranty and comfort exchange details, see our warranties and trials guide.

How Long Different Mattresses Last

Mattress lifespan depends primarily on the materials used. Here is a general guide, though individual results vary based on quality and care:

These are guidelines, not guarantees. A high-quality hybrid with high-density foam and tempered coils may outlast a cheap latex mattress. Construction quality matters as much as material type.

Visible Signs of Wear

Some signs are obvious — you can see or feel them. If you notice any of these, it is likely time to replace your mattress:

• Visible sagging. A dip or valley where you sleep, visible when the bed is stripped. Sagging deeper than 1.5 inches may also be a warranty issue.
• Body impressions. Permanent indentations where your body lies. Light impressions are normal; deep ones that do not recover are a problem.
• Lumps or bumps. Uneven surface texture, often from foam or fiber shifting inside.
• Tears or fraying. Damaged cover or seams that expose the interior.
• Noise. Creaking or squeaking when you move, often from worn coils or loose components.

Comfort and Support Changes

Sometimes the mattress looks fine but no longer feels right. Comfort and support degrade gradually as materials compress and lose their original properties. Signs include:

• Waking up stiff or achy. If you wake up uncomfortable but feel better as the day goes on, your mattress may no longer be providing adequate support.
• Sleeping better elsewhere. If you sleep better in a hotel or guest bed than at home, your mattress may be the issue.
• Tossing and turning. Increased restlessness can result from pressure points that develop as the mattress softens unevenly.
• Feeling your partner move. If motion isolation has worsened, the foam or coils may have degraded.

Hygiene and Allergens

Over years of use, mattresses accumulate dust mites, dead skin cells, sweat, and body oils. Even with a protector, some buildup is inevitable. Signs that hygiene may be a factor:

• Increased allergy symptoms, especially in the morning
• Odors that do not dissipate with cleaning
• A mattress over 8 years old without a protector

A mattress protector and regular vacuuming help, but after 8–10 years, replacing the mattress is the most effective way to address accumulated allergens. For care tips, see our mattress care guide.

When Replacement May Not Be Needed

Before replacing your mattress, check these other factors — the issue may not be the mattress itself:

• The foundation. A worn or inadequate foundation can cause sagging. Check that your foundation is solid, has center support for Queen and larger, and is not itself sagging. See our foundation guide.
• The pillow. Neck and upper back discomfort may stem from a worn pillow, not the mattress. Pillows should be replaced every 1–2 years.
• Sleep position changes. If you have changed sleep positions (e.g., from back to side sleeping), your current mattress may no longer be the right fit — even if it is not worn out.
• Body changes. Weight gain or loss, injury, or aging can change what your body needs from a mattress.

If the mattress is under 7 years old and none of the visible signs apply, try a new pillow or check the foundation before replacing the mattress. If issues persist, visit a showroom near you to compare your current mattress feel against new options.
