How Long Does a Memory Foam Mattress Last?

4.3/5 - (21 votes)

Bed mattresses don’t come cheap, which is why when shopping for a mattress or any other item, one important factor to consider is the usable lifespan of the product. A memory foam mattress is a popular choice because it is one of the most durable types of mattress.

It follows the natural contours of your body and is also sensitive to heat. What’s great about the memory foam mattress is that it goes back to its original shape after the weight is removed.

On average, a memory foam mattress lasts longer compared to the usual spring mattress. This is partly because of the materials used to make a memory foam mattress. Also, the density and the core of a memory foam mattress are two factors that can predict its lifespan.


Dense foam has tightly-spaced cell structures that also affect the overall performance of the product. Foams between 2 to 4 pounds are considered low-density; between 4.1 to 5.5 lbs. are considered medium density; beyond 5.5 lbs., you have a high-density memory foam mattress.

A memory foam with a higher density will last longer than their low-density counterparts because more cell structures will be able to conform and support the weight.

For most people, a medium-density memory foam mattress gives the most comfort as well as durability. For low-density mattresses, you can expect an average of 4 to 6 years of usable lifespan while mid to higher density foam mattresses can give you an average of 10 years or more.


This is the layer of foam underneath the actual memory foam that works to support it. This second layer is actually the foam responsible for supporting the body. High-quality mattresses should have a core of at least 2 lbs. or more since the higher the resilience of the foam, the better.

On the other hand, cores that have densities less than 2 lbs. can break down easily or soften, which could decrease the lifespan and negatively affect its performance.

Although a memory foam mattress is expected to last about 10 to 15 years, it’s life expectancy is also dependent on other factors, like the amount of use, as well as the quality of the product you bought.

Moderately used memory foam mattresses that are slept on around 8 hours a day will last longer compared to those which are slept on more than 10 hours a day or rarely used. How you take care of your mattress will also affect its performance and lifespan just like most products.

Tips on how you can take care of your memory foam mattress

Proper support

Start with a solid bed base that can properly support your weight and the mattress. A memory foam mattress requires a firm base like a platform bed or a solid wood base. A box spring or slats are not recommended for memory foam mattresses. Slats that are too widely spaced can cause the foam to deteriorate quickly.

Rotate your mattress

Although memory foam mattresses are said to be non-turn mattresses, regularly rotating your mattress can help even out and prevent depressions from forming on a portion of the bed caused by the concentration of body weight in specific areas of the mattress. You can do this every six to twelve months for an even wear. Just rotate the bed 180°, no need to flip it.

Use a mattress cover

Spills can occur anywhere, no matter how careful you are. Using a water-resistant or waterproof mattress cover can help you extend the lifespan of your mattress by preventing spills and dust from seeping through it. A mattress cover can also help you prevent odour and mildew problems.

For hygienic purposes, a washable mattress cover will also keep you from sleeping on an unhealthy environment full of sweat and dead skin cells. Most manufacturers also require this if you want to preserve the warranty coverage of your product.

Regular cleaning

Although a mattress cover can protect the surface from most dirt and spills, cleaning your memory foam mattress on a regular basis will help prolong its life. This will prevent bacteria, mould and mildew from slowly building up inside, which can cause your foam to deteriorate quickly.

Also, be mindful of the cleaning products that you use because some of the commonly used household chemicals are too strong for the mattress and can actually reduce its life.
