When to Replace a Mattress

  • Are You Leaving a You-Shaped Imprint? A body-shaped impression on the surface of your bed when you get up in the morning is a sign that your mattress is on the fritz.
  • Are You Hearing a Mattress Symphony? Squeaks and screeching are signs that your coils are on their way out. While you may not realize it, your support level has probably already decreased significantly.
  • Do You Detect an Odor? If smells of mold and mildew are coming from your mattress. You might even notice that you're sneezing or coughing when you spend time on your mattress if you have allergies to the mattress.
  • Do You Hurt Every Morning? Waking up in pain could mean that your mattress isn't supporting you at night. Bad mattresses are notorious for causing pain in the back, neck, hips, and shoulders.
  • Is It Impossible to Get Comfortable? Tossing and turning? An uncomfortable mattress can cause you to feel physically and mentally agitated at night.

Mattress Lifespan? (By Type)

The aging process of a mattress depends on the type of mattress you buy and how the mattress is manufactured.

How Long Does a Futon Last?

A futon can last ten years or more. But the cotton material within will compress over time, making the futon harder.

If you’re looking for a very plush sleeping situation you probably aren’t going for a futon anyway, as a typical futon feels like a firm mattress. You may find over time that the futon becomes overly firm. That’s when it’s time to buy a new mattress.

How Long Does an Air Mattress Last?

The lifespan of an air mattress varies wildly depending on how you treat it. Putting excess weight on an air mattress, moving around a lot while you sleep, or getting close to sharp objects could drastically reduce its lifespan.

No matter how careful you are, holes and deterioration in the seams are inevitable. If you find yourself repairing leaks a lot, or your air mattress has a funky smell, it’s time to buy a new mattress.

How Long Does an Innerspring Mattress Last?

An innerspring mattress should last about ten years. But that depends on how you treat it, and the quality of the construction of the mattress.

No matter how strong the coils are, they will break down faster if they are absorbing a lot of weight or unnecessary stress. (Kids! No jumping on the bed!) If you start to sink into your innerspring bed, that’s a sign that the coils are failing and it’s time to buy a new mattress.

How Long Does a Hybrid Mattress Last?

A hybrid mattress is an innerspring mattress with a top comfort layer made out of more modern material like gel or memory foam.

The coils that provide the main body of the mattress should last about ten years. The comfort layer should be designed to last just as long, but the material may get less comfortable over time. If you notice lumps or sagging in the comfort material, it’s time to buy a new mattress.

How Long Does a Waterbed Mattress Last?

If you care for it properly, a waterbed mattress should last 10-20 years. That care is key, however. You need to buy something called a “waterbed conditioner” to treat the water in the bed. Otherwise, microbes or minerals in the water can break down the vinyl mattress.

You also will likely need to patch the occasional leak. If your waterbed starts to develop frequent leaks, it’s time to buy a new mattress.

How Long Does a Memory Foam Mattress Last?

A memory foam mattress should last 8-10 years. The lifespan of a memory foam mattress depends on the density of the foam, and the weight of the person sleeping on it. Lower-density foam mattresses are less expensive, but also more prone to sagging.

How Long Does a Latex Mattress Last?

The lifespan of a latex mattress depends heavily on which latex mattress you buy. Some manufacturers offer warranties as long as 25 years, but check the fine print — by year 25, you may not get full price for a defective mattress, just a discount towards a new one.
