Foam Forever: How long does foam actually last?

When buying a new mattress, every guide you read will tell you to choose one that is most durable. The lifespan of the new mattress, therefore, becomes a crucial factor when you replace your old one.

How long does a mattress last? Well, that depends on a whole lot of factors. Especially the quality, the make, the density, etc.

According to sleep solution experts, a memory foam mattress lasts longer than average. For this reason, memory foam is a top choice amongst buyers.


Like we already mentioned, what a mattress contains determines its durability. A memory foam mattress’ density of both its material as well as its core, contribute immensely to its lifespan.

Finding the right density then becomes important when shopping for memory foam. A higher density mattress will have more cells to support the sleeper’s body weight by conforming to the latter. As a result, it lasts longer than other mattresses.

But this could hamper the comfort as high density equals to greater viscosity.  Striking a balance between durability and comfort will help you find the perfect mattress for you.

According to memory foam mattress brands around the world, low-density foam mattress usually lasts somewhere between 5 to 6 years while the high-density ones can last longer than 10 years. This, however, also depends on how the mattress is used and taken care of.

Support base 

The support foam layer that is typically found beneath the actual memory foam, becomes the second factor determining the longevity of the mattress.

This layer takes credit for supporting your body along with the memory foam layer. However, if this layer is of low quality, then the mattress will not last long.

High resilience forms are best as they don’t break down or soften, and therefore, there is no compromise made in terms of support as well as durability.


Many blogs will tell you that the warranty offered by a product is a significant indicator of its durability. This, however, is not necessarily true. Though it is a factor, you need to take the warranty period given with a pinch of salt.

If you want a good quality memory foam mattress, you need to look for one that offers a minimum of 10 years of full coverage. Why? Because as we just saw, that is its average lifespan.

Of all the mattresses, innerspring mattresses have the worst lifespan and durability. This is because padding layers start losing firmness pretty early and so do the springs that cannot be altered. While latex and memory foam both have impressive durability, foam outperforms latex in most of these areas, and therefore, would be our pick.

Apart from its durability, there are other factors that make foam the top choice amongst customers. Because if your mattress does last long, but loses all its other properties during that time (example – spring mattress), then is it really worth it?

The other reasons that make foam mattress great –

  • Offers motion isolation – Memory foam mattress has an advantage over other mattresses, and that is, its ability to isolate motion. This property is especially beneficial if you sleep with a partner and your partner turns and tosses in their sleep through the night. So every time your partner moves, the mattress absorbs the motion and isolates it so that you don’t get disturbed in your sleep.
  • Gives greater firmness – Nowadays memory foam comes with varying firmness, with a thick lower base, and a thinner top layer. This means, you can use the mattress the way you want depending on the kind of thickness or firmness you are looking for. This helps you choose the best sleeping surface according to individual requirements and changing weather conditions. What is the weather advantage you ask? While you can use the harder side during winter, you can sleep on the softer side during summer.
  • Alleviates back pain – Memory foam mattress conforms to the body shape of the sleeper. It also evenly distributes his or her body weight, thus ensuring that there is no pressure on the neck, the hips and the joints of the sleeper.  As a result, the mattress gives relief from back pain and/or other back injuries.
  • Maintains natural spinal alignment – Since the mattress does not bend your spine in an unnatural way, it can improve your posture over time.
  • Allows temperature neutrality – Unlike previous memory foam mattresses, the ones designed today come with advanced cooling properties and breathable fabric that ensure your mattress does not trap body heat, which in turn, makes sure you sleep comfortably through the night.
