Memory foam mattresses are a popular choice for many people because they contour to your body, provide pressure relief and don’t transfer movement. They’re also low-maintenance and generally last longer than other types of mattresses. But how long do memory foam mattresses last? The answer is … it depends. Several factors can affect the lifespan of your memory foam mattress, including how often it’s used and how well you take care of it. We’ll break down everything you need to know about memory foam mattresses, including how long they last and how to prolong their lifespan.

What Is a Memory Foam Mattress?

Memory foam is a type of viscoelastic polyurethane foam that offers cushioned support and pressure relief. It was first developed by NASA in the 1970s as a material to cushion astronauts during take-off and landing. Today, it’s a popular material for mattresses, pillows and other bedding products. Memory foam mattresses differ from traditional innerspring mattresses in several ways. First, memory foam contours to your body, providing support and pressure relief where you need it most. Also, memory foam isolates motion, so you’re not disturbed by your partner’s movements during the night.

Replacing Your Memory Foam Mattress

Memory foam mattresses can last up to ten years, averaging around eight years. Of course, this is just an estimate. Some people have had their memory foam mattresses for much longer. In fact, some customers are telling us they’ve surpassed the ten-year mark before needing a replacement. There are a few factors that will affect how long your memory foam mattress will last, including:

1) Frequency of Use

This may sound like common sense, but how often your memory foam mattress is used will significantly affect its lifespan. If you sleep on your memory foam mattress every night, it will probably need to be replaced sooner than if you only use it occasionally. For example, a memory foam mattress used in your guest bedroom may last much longer than one used in your primary bedroom if you don’t have frequent visitors.

2) Who’s Using It

Another factor affecting how long your memory foam mattress will last is who is using it. For example, a child who jumps on the bed daily and uses it as a play area is likely to shorten the mattress’s lifespan compared to an adult who simply sleeps on it. In addition, if two sleepers use the same mattress, it may need to be replaced sooner than if only one person is using it. This is because multiple people mean more wear and tear — and thus more frequent replacements.

3) Quality of Materials

The quality of the materials used to make your memory foam mattress will also affect its lifespan. Higher-density foams, for example, will last longer than lower-density foams. Likewise, a thicker memory foam mattress will usually last longer than one that’s thinner and less dense. Simmons Beautyrest memory foam mattresses are a great example of high-quality memory foam mattresses built to last.

4) Using a Proper Base

It’s essential to use a proper base for your memory foam mattress — one that is sturdy and supportive. A weak or unstable base can cause the mattress to sag over time, which will shorten its lifespan. But do you need a box spring with a bed frame for your memory foam mattress? The truth is, you can use a box spring or a foundation, but it’s not necessary. In fact, memory foam mattresses work just as well on a solid platform — like a wooden slatted bed frame — because it allows the mattress to breathe.

5) Care and Maintenance

Taking care of your memory foam mattress is important if you want it to last. If you’re interested in prolonging the lifespan of your mattress, we recommend following these tips:

  • - Use a mattress protector – A mattress protector will help keep your memory foam mattress clean and free of dust, dirt and other debris. It can also protect against spills and stains.
  • - Rotate or flip your mattress – Rotating or flipping your mattress every six months will help evenly distribute wear and tear. This is especially important if you sleep in the same spot every night.
  • - Keep it clean – In addition to using a mattress protector, you should also vacuum your memory foam mattress regularly to remove any accumulated dust or dirt. Be careful not to use too much force, as this could damage the foam.
  • - Only use gentle cleaners – Life happens, and sometimes your mattress will need to be cleaned. When this happens, use gentle cleaners that won’t damage the foam. Avoid using harsh chemicals or abrasive scrubbers. Diluting with water can also help.

Tips for Buying a New Memory Foam Mattress

If you’re shopping for a memory foam mattress, there are a few things to remember: 

  • - Foam Density – Pay attention to the density of the memory foam. Higher-density foams will be more supportive and durable than lower-density foams. 
  • - Warranty – Ensure the mattress has a good warranty so that you can get it replaced if there are any issues. Be aware that some warranties require you to use a mattress protector to keep the warranty valid. Inquire about these details before you buy.
  • - Trial Period – Many mattress companies offer a trial period so that you can test out the mattress in your home. This is a great way to ensure you’re happy with the mattress before committing to it. 

Final Thoughts on Memory Foam Mattress Lifespan

And if you’re looking to prolong the lifespan of your mattress, we recommend using a mattress protector, rotating or flipping it every six months and keeping it clean. Avoid harsh chemicals or abrasive scrubbers, and only use gentle cleaners if necessary. Following these tips can help you get the most out of your memory foam mattress.
