How long does a mattress last?

By Callie Paige

We spend a third of our lives asleep. That’s a whopping 25 years if we live to the ripe old age of 75, which will be no mean feat if Donald Trump carries on like he is.

So when you’re considering which mattress to buy, asking ‘how long does a mattress last’, is a pretty valid concern. As with most research done on mattresses, there’s no straightforward answer, and much of it differs from person to person.

What you also need to think about is the performance of your mattress over the years you own it. Take a car for example - it runs like a dream for the first 3 years, and then slowly problems develop as wear and tear affects different components.

However, what we can do is provide advice and share our considerable experience of the mattress industry, which should give you an idea of how long your mattress will last. 


Can you increase how long a mattress lasts?

The less you use it, the longer it’ll last. But where’s the fun in that? Many people will stick to using their bed for sleep, but as we found out in a recent survey, for all the people that swear by only sleeping in bed, nearly the same amount like to enjoy a bed for everything it can give. You know what we’re talking about…eating and watching Netflix!

Although we have to say, if you’re looking to make your mattress last a little longer, if you do get up to more in bed than just sleep, we recommend you regularly clean it to make sure in a couple of years time, you’re not left embarrassed.

A final thing to note on how long does a mattress last, is that weight matters. Finding a bed that supports you if a key consideration when purchasing - too firm or too soft, and you could find your pressure points unsupported, potentially giving you back trouble. The best thing to do is test your mattress out to make sure it’s going to provide the support you need. Most brands give you 100 nights, Sid gives you 120 nights. 

Material - How long does a mattress last?

One of the obvious considerations is the material your mattress is made out of. This is taken to the extreme when you consider the variations in quality between each material - some memory foam mattresses are naturally going to be better than others. Check out the 7-layer composition of Sid, for example.

Speaking generally, to get the most out of the money you’ll spend on a mattress, it should last you at least three years, all the way up to fifteen years if you’re investing in quality. Below we’ll go into how long your mattress should last dependent on material.


Latex remains one of the hardest wearing materials when it comes to mattresses. This is due to the multi-layer nature of latex, meaning that when one of the layers has worn out - usually the top layer for obvious reasons, you can easily replace it and your mattress will feel like new. To make the most of Latex mattresses, you need to keep on top of maintenance in particular, as lifespans can reduce, and costs increase if you don’t look after them.

Memory Foam

The popularity of memory foam mattresses has skyrocketed in recent years, with the evolution of bed in a box brands (although if we’re honest, there’s only one of those you should be choosing - Meet Sid).

Since 2014, consumer-focused brands have revitalised the industry with clever marketing and basic memory foam mattresses. Often these mattresses comprise of multiple layers of different types of foam, with a single section being memory foam. This means the support can often start to sink around the most used areas of your mattress, compressing the foam and reducing the support provided.

When looking for a memory foam mattress, quality is a necessity. Recent advances in memory foam technology have resulted in mattresses that comprise of high-quality layered compositions, with each layer designed for a specific purpose. For example, Sid contains a Graphyx memory foam layer that combats a common issue with memory foam mattresses - overheating, above a high-density Revo foam that provide the support you need.

All of this begs the question - how long does a memory foam mattress last? Many memory foam mattresses will last around 10 years, however the best in this category are guaranteed to perform for up to 15 years.


Innerspring mattresses are still one of the most common mattresses in the UK, however, they’ve become notorious for their poor quality - especially when it comes to longevity. Naturally, coiled springs will lose their bounce over the years, resulting in a lumpy mattress. The mattress itself is also a breeding ground for bed bugs, as the cavity where the coils are stored are perfect for tiny critters to hide.


How do you know if you need a new mattress?

Well, we think we’ve covered the obvious points. If your back starts to hurt, it’s probably time to change. Having a sprung mattress over 3-5 years could also mean it’s time to update, think of all those bugs…

But we want you to think differently when it comes to your mattress. No more beige oblong. Sid is a mattress that caters to your changing tastes over the 15 years you’ll own it, thanks to its unique interchangeable cover.

Use a mattress topper. A cushioning layer on the top of your mattress provides extra comfort and vital protection against your mattress getting damaged. Sid has an integrated luxurious quilted top layer, that is easily removed by the premium quality zipper.

Another important factor is rotating your mattress. While memory foam mattresses like Sid don’t need to be flipped, due to their unique composition, by rotating the mattress every month you can even the pressure applied to the memory foam.
