How Long Should You Keep Mattress? A Practical FAQ Guide

If you’re wondering “How Long Should You Keep Mattress” before replacing it, you’re not alone. Mattresses don’t last forever, and knowing when to move on can make a big difference to your comfort and sleep quality. This guide answers the most common questions about mattress lifespan and when it’s time for an upgrade.

How long should you keep a mattress on average?

Most mattresses are commonly kept for about 7–10 years, but the right time to replace yours depends on how it looks, feels, and performs, not just its age.

In general, you may want to start closely watching your mattress after about 5–7 years of use. From that point on, signs of wear, discomfort, or changes in your sleep are more likely to appear.

What affects how long you should keep a mattress?

Several everyday factors influence how long you should keep mattress in good condition:

• Mattress type – Foam, hybrid, latex, and innerspring mattresses can wear differently. Some hold their shape longer than others, depending on materials and construction.
• Body weight and number of sleepers – A mattress used by two people, or by someone with a higher body weight, tends to wear faster than one used lightly.
• Usage – A mattress used nightly will age more quickly than one in a guest room that’s slept on occasionally.
• Care and support – Using a proper base or foundation and rotating your mattress (if recommended by the maker) can help it stay more even and supportive over time.
• Environment – Excess moisture, poor ventilation, and pets can all affect how long materials stay fresh and intact.

Because of these variables, it’s more accurate to focus on how your mattress behaves now, rather than relying only on its age.

What are the clear signs you should replace your mattress?

Instead of asking only “How Long Should You Keep Mattress,” it helps to look for practical warning signs:

• Visible sagging or deep impressions, especially where you usually lie
• Lumps, bumps, or coils you can feel through the surface
• Frequent tossing and turning or difficulty getting comfortable
• Waking up feeling stiff or achy when you didn’t before
• Noisy springs that creak or pop with movement
• Changes in your sleep quality that improve when you sleep elsewhere (like on a different bed)

If you notice several of these at once, your mattress is likely past its best, even if it isn’t very old yet.

How do different mattress types compare for lifespan?

Here is a simple overview of general lifespan ranges many sleepers experience:

These are typical ranges, not guarantees. How you use and care for your mattress has a strong effect on how long it actually lasts.

Does a warranty tell you how long to keep a mattress?

A mattress warranty is often longer than the realistic comfort life of the bed. For example, a warranty might cover certain defects for many years, but:

• It usually only applies to specific issues, like deep sagging beyond a set depth.
• It does not guarantee you’ll feel comfortable for the full warranty period.
• Normal softening, body impressions within a limit, or personal comfort changes are typically not covered.

So, do not rely on the warranty alone to decide how long you should keep a mattress. Use it as a reference, but pay more attention to what you see and feel.

How can you help your mattress last closer to its full lifespan?

A few simple habits can help you keep your mattress in better shape for longer:

• ✅ Use a supportive base that’s appropriate for your mattress type
• ✅ Rotate it regularly (if recommended) to reduce body impressions
• ✅ Use a mattress protector to help guard against spills and dirt
• ✅ Keep pets’ claws and jumping off the surface when possible
• ✅ Avoid sitting on the same edge every day to limit uneven wear

These steps can’t stop normal aging, but they can help delay obvious sagging or damage.

Is it okay to keep a mattress if it’s older but still feels fine?

Yes. Age alone doesn’t mean you must replace your mattress. If:

• It still feels supportive and comfortable
• There is no major sagging, damage, or odor
• You sleep well and feel rested

…then you can reasonably keep using it, even if it’s older than typical guidelines. The key question is whether it still meets your comfort needs today, not how many years it has been on the bed frame.
