When to Replace a Mattress
Old mattresses are a leading cause of poor-quality sleep, which has been linked to everything from high stress levels to obesity and a weak immune system.
But the side effects of sleeping on an old mattress aren't limited to poor-quality sleep. By failing to provide the support your body needs, it can lead to back and neck pain. Meanwhile, the build-up of dust mites can worsen your allergy symptoms.
Replacing your old mattress could make a serious difference to your health and wellbeing. Read our guide to find out how long the average mattress lasts, and learn about the warning signs that indicate yours is past its best.
How often should you change your mattress?
The Sleep Council recommends that you change your mattress every seven years as, after this length of time, it will have been subjected to more than 20,000 hours of wear and tear. That's bound to have taken a toll! So, if you're wondering whether it's time to replace your mattress, the first thing you should consider is how long you've had it.
How long does a memory foam mattress last?
Memory foam mattresses can last 10–20 years — much longer than traditional sprung mattresses. This is because, while they mould to your body while you sleep, they're able to return to their original shape once you've gotten out of bed.
However, it's worth noting that a mattress might need replacing sooner or later than its recommended lifespan, depending on its quality, how it's looked after, and how often it's used. You should use your judgement and look out for signs that your mattress is negatively affecting your quality of sleep.

What are the signs that your mattress needs to be replaced?
Once you've had your mattress for five years, you should start to pay more attention to its condition. We would recommend giving it a quick inspection whenever you change your sheets, so you can spot any problems before they begin to cause you too much trouble. Here, we'll outline some of the most common issues that signal your mattress could be past its best.
Is your mattress showing signs of wear and tear?
You should check your mattress for visible signs of wear and tear whenever you change your bed sheets. If it looks worn, is lumpy, or has a visible dip where you tend to lie, it's time to replace it. You should also pay attention to whether your mattress has become noisy. If it creaks, groans, or pings when you're trying to get to sleep at night, this is also a sign that you should be looking to invest in a new mattress.
Do you wake up tired or sore?
We all know how important it is to get a good night's sleep. If you regularly wake up tired and sore, it's likely your mattress has stopped supporting your body properly while you sleep. This can cause you to toss and turn through the night, which will prevent you from getting the rest you need. If this is something you struggle with, it's probably time to look for a replacement.
Does it feel uncomfortable?
When you run your hand over the top of your mattress, can you feel any springs or lumps that might prevent you from getting a good night's sleep? Mattresses can grow less and less comfortable over time, which means you might not notice these problems straight away. As a result, you should inspect yours on a regular basis, and look to replace your mattress if it's old and much less comfortable than it used to be.
Is your mattress keeping your partner awake?
If your partner is tossing and turning all night, it's going to ruin your quality of sleep — especially if your mattress isn't in the best condition and you can feel every move they make. So, if you think your mattress might be keeping your partner up all night, it's probably time to invest in a new one.
Our Duo Feel mattresses are ideal for couples, as they allow you to choose different levels of firmness for each side of your bed. This means they can cater to both of you, even if you have different sleeping styles.
Are your allergy or asthma symptoms getting worse?
Over the years you've had it, your mattress will have collected a surprisingly large amount of dead skin cells, dust, and dust mites. These are known to aggravate the symptoms of allergies and asthma, which is why you might find that you suffer particularly badly when you're in bed at night. If you've had your mattress for five years or more and this is something you're experiencing, investing in a new one is likely to help.
Our memory foam mattresses are great for allergy and asthma sufferers, as they have a solid core, which leaves much less space for dust mites to gather. There are also no plastic or metal surfaces within memory foam mattresses, which makes it much more difficult for irritants to attach themselves to your bed.
Have your body's needs changed?
As we age, our bodies change, and this will usually mean that our needs change too. While you might choose softer designs when buying your first few mattresses, it's typically best to opt for firmer variations as you grow older. This is because these will provide much more support for your joints and spine.
If you think you need a firmer mattress, our pocket sprung mattresses are ideal. Their individually wrapped springs contour to your body, which relieves pressure and should provide all of the support you need for a great night's sleep.
Once you've had your mattress for five years, you should pay much closer attention to its condition. If it is coming to the end of its lifespan, looks particularly worn, or is no longer providing you with the support you need, it's time for an upgrade.
If you think you need a replacement, take a look at our entire range of mattresses, where you'll find designs that cater to any needs you might have. We offer single, small double, and double mattresses in a variety of state-of-the-art materials, including memory foam, latex and hybrid styles. Looking for something a bit bigger?
