How Often Are You Supposed To Change Your Mattress? A Practical FAQ Guide

If you’re wondering “How Often Are You Supposed To Change Your Mattress”, you’re not alone. Many people aren’t sure when a mattress is truly “worn out” or if they can safely keep using it. This guide walks through what most sleepers can expect, what really matters, and how to tell when it’s time for a replacement.

What does it actually mean to “change your mattress”?

When people ask “How Often Are You Supposed To Change Your Mattress”, they usually want to know:

How many years a mattress typically lasts
How to recognize signs of wear
Whether different mattress types last for different lengths of time

In general, changing your mattress means replacing your primary bed with a newer one once the old one no longer supports you well, feels uncomfortable, or shows obvious damage.

Most modern mattresses are designed to be used for several years with regular, everyday sleep. However, the actual lifespan can vary based on:

Mattress type and materials
How heavily it’s used (nightly vs. guest room)
Body weight and sleeping style
How well it’s cared for

So, how often are you supposed to change your mattress?

A common guideline is that many mattresses are ready for replacement around the 7–10 year mark. This is not a strict rule. Some mattresses feel worn earlier, while others remain comfortable and supportive for longer.

Instead of following a fixed number, it helps to combine time with real-world signs:

If your mattress is under 5 years old and still feels supportive and comfortable, it usually doesn’t need changing.
Between 5–10 years, it’s useful to check it regularly for sagging, lumps, and changes in comfort.
After about 10 years, many sleepers notice enough wear that a replacement becomes more likely.

The key idea: Change your mattress when it no longer supports comfortable, restful sleep — even if it hasn’t reached a certain age yet.

What are the most important signs it’s time to replace your mattress?

Here are some common indicators that your mattress may be past its best:

Visible sagging or deep body impressions that don’t spring back
Lumps, bumps, or uneven areas you can feel through the cover
You frequently wake up stiff, sore, or uncomfortable, but feel better after sleeping elsewhere
You roll toward the middle unintentionally or feel like you’re “stuck” in a dip
The mattress creaks, shifts, or wobbles more than it used to
You notice more motion transfer, like feeling every move from a partner
It has tears, frayed edges, or broken components (such as coils poking or bent)

If several of these describe your current bed, it’s a strong sign that you’re due for a change, regardless of the exact age.

Does mattress type change how often you should replace it?

Mattress materials can affect how they age. While there are always exceptions, many sleepers find:

Innerspring mattresses may lose support or develop sagging over time, especially in the center.
Foam mattresses can develop body impressions or feel softer and less supportive after years of use.
Hybrid mattresses (foam + coils) tend to blend both behaviors, with potential wear in both layers.
Latex mattresses are often known for staying resilient for longer, though they can still soften with age.

None of these types last forever. The same rule applies: how the mattress feels and performs matters more than the label or material.

How can you help your mattress last longer?

While you can’t stop natural wear, you can often slow it down with simple habits:

Use a supportive base that matches the mattress type
Rotate the mattress periodically if the manufacturer allows it
Use a mattress protector to guard against spills and stains
Avoid jumping or heavy sudden impacts that can damage internal layers
Clean the surface regularly according to the care instructions

These steps support your mattress over time, but they don’t remove the need to eventually replace it.

How often are you supposed to change your mattress if you sleep differently?

Life circumstances can shorten or extend the practical lifespan of a bed:

Heavier sleepers may notice sagging or impressions sooner.
Couples, especially if both partners share a smaller bed, may see more concentrated wear.
A guest room mattress that’s rarely used often remains comfortable for longer.
Children’s beds may be replaced more often as kids grow and their comfort needs change.

In these situations, asking “How Often Are You Supposed To Change Your Mattress” is really asking, “Is this mattress still doing its job for my body and my sleep?” If the answer feels like “not really,” that’s a sign to consider a change.
