How Often Should You Replace Your Mattress

Read more about Mattress

How do you know when your mattress needs replacing? It might be sooner than you think. Find out if you're ruining your sleep and how to tell when you need a new mattress.

How Frequently Should You Replace Your Mattress?

Some experts say you should buy a new mattress every 7-10 years. But the timetable depends on several factors, including:

  • The type (including inner spring, memory foam, latex, waterbed, etc.)

  • The amount of wear and tear your mattress experiences

  • How you feel after sleeping on your mattress

  • If the circumstances in your life change (e.g., have a new partner, gain/lose weight)

While the rule of thumb says you should change your mattress every 8 years, this doesn't apply to everyone. If you're still sleeping well on your mattress and it show no visible signs of deterioration, don't feel pressured to make the switch.

When to Change Each Type of Mattress

Here's a breakdown of the best time to change each type of mattress:

Innerspring Mattress
This type lasts 7-8 years with regular use. A continuous coil innerspring mattress may last as long as 10 years due to the increased stability of the longer coil.

Memory Foam Mattress
The extra layer of foam helps prolong the life of the mattress, since the springs don't get as much direct contact. Some people get up to 10–15 years out of their memory foam mattress.

Latex Mattress
A latex mattress is one of the longest lasting mattresses available today with a lifespan up to 15 years.

Latex has the most elasticity, resulting in less premature sagging. Many manufacturers allow the replacement of the top layer of a latex mattress too, making it last even longer.

What's the Cost of a New Mattress?
You could spend anywhere from a few hundred to several thousand dollars on a new mattress. It depends on the type, quality, and where you buy it.

Shopping for a mattress online can save you money. Many mattress companies offer free trial periods for as long as 100 nights to decide if you like it.

Why You Should Replace Your Mattress

The best reason to replace your mattress is a lack of quality sleep. If you are starting to wake up feeling rested, it may be time for a change.

A poor night's sleep can put your health at risk. You may have an increased risk of health conditions, including:

  • Stroke
  • Heart disease
  • High blood pressure
  • Diabetes
  • Depression

Can a mattress last 20 years?
In rare cases, a mattress can last 20 years. The longevity of your mattress depends on several factors, including the quality of its parts and the way you've taken care of it.

Memory foams and latex mattresses can last up to 15 years, much longer than the average innerspring. In the end, it's up to you how long your mattress lasts. If you're still getting a good night's sleep, you might not need to make a change.

how to tell when you need a new mattress

No matter what type you have or how long you've had it, it may be time for a replacement if:

  • You feel like the coils poke you in your sleep.

  • Your bed has become noisy.

  • You just can't get comfortable or wake up sore.

  • There are obvious dents or saggy areas in the mattress.

  • You have an allergic reaction or frequent congestion.

Other Reasons to Change Your Mattress
Sometimes changes in your life, not your bed, may require a new mattress. If you've lost or gained weight or have a new partner, it may be time for a change.

Prolong the Life of Your Mattress

There are a few things you can do to help extend the life of your mattress:

Get a Mattress Pad/Protector
These provide an extra layer of protection from dust mites, dander, sweat, and body oils.

When should I replace my mattress pad/protector?
A quality mattress pad/protector can last for several years. Be sure to clean it regularly and look out for tears or signs of fraying.

Wash Your Bed Linens Weekly
Regular care of your bed linens can help prevent the accumulation of sweat, body oil, and dust from seeping into the mattress.

Vacuum Your Mattress Semi-annually
Sprinkle your mattress with baking soda and let it sit for 15–20 minutes before vacuuming it off. This will deodorize the mattress and remove any debris that might have seeped through the bed linens or mattress cover.

Don't Let Kids Jump on the Bed
Kids jumping on the bed can ruin the integrity of the springs, causing your mattress to sink.

Keep Pets off the Mattress
Your pet's dander, body oils, and urine can eat away at the fibers of the mattress.


Do you need to replace the box spring with the mattress?
A good box spring can can last 15-20 years. You won't necessarily need to replace yours when buying a new mattress. However, it is important to ensure that your box spring provides the support that you need.

The telltale signs that you need a new box spring include:

  • Broken slats
  • A sagging box
  • Squeaky springs

Will rotating a mattress help preserve it?
Flipping your mattress is beneficial ONLY if you have a double-sided mattress. You should doublecheck to make sure.

If you rotate your mattress every 3 months, you could prevent premature and excessive wear and tear. But if you are already experiencing issues, you may still need a new one.

How often should pillows be replaced?
Your should replace your cheap cotton or polyester pillow every 6 months or so. Higher quality pillows, like memory foam, can last 1-2 years or even longer.

But regardless of type, pillows aren't meant to last forever. They tend to be breeding grounds for mites and allergens. If you can't remember the last time you got a new one, it may be time.

Bottom Line

Your mattress may last anywhere from 7 to 20 years. But when your quality of sleep diminishes, it's time to make a change.

Remember: A new mattress isn't an added expense—it's an investment in your overall health and wellness.
