How Often Should You Change Your Mattress To Ensure Clean Environment?

We spend almost a third of our lives on a mattress. That is why buying a new mattress should be one of the most important investments of every person. A quality mattress is most deserving of a great night’s sleep.

Sleep experts say that if you are wondering if it is time to buy a new mattress, then it probably means you should. If you sleep in your bed every night, you spend between 5 and 10 hours lying on the mattress. That’s over 50 hours a week, much longer than your workweek of five eight-hour days.

This leads us to the conclusion that every mattress is exposed to a very challenging task, and that is to give us refreshing sleep. Sleep is one of the most important aspects of human life because it has a huge impact on our energy level and our health. So if you wake up at night or suffer from insomnia, the mattress can be the culprit. We will tell you how often you should change your mattress to avoid using old mattress for too long until the first symptoms of insomnia appear.

    Mattress types and durability

    You can find many different types of mattresses on the UK market, but four types are the most popular – memory foam, latex, innerspring and hybrid. The quality of the mattress itself has a greater effect on durability and how long it will last than just the type, but certainly the type also plays a big role. When buying a mattress you can approximately know when you will have to change it according to the type.

    Memory foam

    Memory foam has become the material chosen by the largest number of customers who want to buy a mattress and pillow. There are many reasons why memory foam is popular. Some of the reasons are comfort, support, pressure relief and motion insulation. Also, a memory foam mattress can be suitable for all sleep positions.

    When we talk about durability, it mainly depends on the foam density, which we’ll talk about later. On average, they last about 5 years. All foam mattresses tend to sag, but if you rotate them regularly and flip, if it is a two-sided mattress, you can significantly extend the service life, so it is not uncommon for memory foam mattresses to last 10 years.


    Our extensive experience with sleep products has shown us that latex mattresses have the longest lifespan of all mattresses, as they often last over 10 years. Latex is such a durable material that you will not notice dents and damage even after many years.

    Also, you don’t have to flip and rotate latex mattresses as often as memory foam mattresses. It is enough to do it once a year and that way you will avoid sagging.


    Of these 4 types, innerspring mattresses have on average the shortest service life, but this is not some significant difference compared to memory foam mattresses for example. Innerspring mattresses almost never last 10 years, but between 5 and 8 years, since the longevity of coil system is not that great.

    However, the quality of coils is improving from year to year, so almost every new model of innerspring mattress lasts longer than the previous one. And by rotating and flipping you can also extend its service life.


    Most sleep companies report that hybrid mattresses have become the best-selling type of mattress and that is not surprising, as they combine the best of both worlds. You get the characteristics of memory foam and innerspring mattresses in one, and also in this way the downsides of both types are significantly reduced.

    How long a hybrid mattress will last depends on the quality of the coil system and foam density. If you buy a premium hybrid mattress, with proper maintenance, it will last you at least 6 to 8 years, and in many cases over 10 years.

    Factors that influence the durability of a mattress

    As we have already said, some other factors have much more influence on the durability of a mattress than just the type of mattress. In this section, we will tell you what these factors are and how they affect durability.

    Material and quality of it

    When we say material, we mean the material used for cover in which the mattress is encased. Different synthetic materials are usually used, but sometimes you can also find cotton, silk and many other materials. The choice of material but also the quality of it, is crucial for how long it will take until you notice first signs of wear and tear. Although wear and tear of cover will not have a greater impact on the quality of your night’s sleep, no one wants to sleep on ruined mattress.

    Another very important thing is workmanship. The best foam and the highest quality materials can be used, but if the level of workmanship is low, then the mattress cannot be durable. This is especially important for mattresses that have multiple layers. Such mattresses are most durable when hand tufted and least durable when layers are glued.

    Foam density

    When buying a memory foam mattress, but also a hybrid, foam density is the best indicator of how long the mattress will last. High density foam may last twice as long as low density foam. Density is measured as mass per unit volume. It is expressed in pounds per cubic foot (PCF).

    The more foam there is in a given area, the denser and heavier the foam is. Low density foam has less than 3 PFC, and high density foam over 5 PFC. Our recommendation is that the mattress on which you often sleep has at least 4 PFC and preferably 5 and more. While for the guest room, for example, you can buy a low density foam mattress, because it will rarely be used and thus service life will not be short. Also, keep in mind that high density foam is very firm, especially the first few nights. So if you are side sleeper who like softer mattress, than go for medium density and not high density, since durability is not the only feature you have to pay attention to when buying mattress.

    Coil gauge

    As foam density is very important for memory foam mattress, when you are on the market for innerspring, pocketed coil, or hybrid mattress, then you need to know coil gauge.

    Mattress coil gauge you should aim is for 12 to 15. In contrast to foam density, lower coil gauge means firmer mattress and more durability. The lower the gauge, the thicker the wire and therefore firmer and longer-lasting is mattress. Pay attention to the number of coils as well as the type, not just the thickness of the wire. The higher the coil count, the more comfortable the mattress will be. There are hourglass coils, pocketed coils and continuous coils, and pocketed coils are considered a premium option.

    How to know that it’s time to replace a mattress?

    You don’t need to be clairvoyant or sleep expert to know when to replace your mattress. Just pay attention to the following sings and it will be clear to you whether the current mattress is still good or it is time for a new one.

    5+ year old mattress

    If it’s been 5 or more years since you bought the mattress, you should at least consider whether it’s time to buy a new one. Of course, this is not the rule, because most high-quality mattresses will provide the same performance after 5 or 6 years as on the first day.

    But also, there is a possibility that your body is accustomed to the mattress, but that actually there are many red flags that indicate that a new mattress is needed. So think about when you bought your mattress and if half a decade has passed, do a basic inspection.

    Poor sleep quality

    Poor sleep quality can be the result of so many causes. It can be a health problem, stress, depression, anxiety, aging and so on. But we must not forget that the cause of poor sleep quality, which includes the inability to fall asleep, short and segmented sleep, can be worn out mattress.

    Uncomfortable mattress maybe be the reason you can’t sleep. Or it has lost bounce, so it no longer adjusts to your current position. Also, maybe motion insulation is significantly worse than when you bought it, so tossing and turning of your partner is waking you up constantly.

    Visible damage of the mattress

    The most obvious sign that you need to buy a new mattress is visible damage on your current mattress. If those damages are solely on the cover, then that’s not a big deal and you can probably use it for few more years. Alternatively, you can look for another high-quality mattress protector to provide it with the additional protection. 

    But if you also notice sagging, lumps, damaged coils and similar things, then it’s time to replace it. Such a mattress is no longer usable and instead of good night’s sleep, it will give you joint pain, back pain, lack of energy and insomnia.

    Frequent allergy problems

    Nearly a quarter of the British population has had allergies at least once in their lives. That’s why a mattress will certainly not be the first thing you blame for frequent allergy problems.

    If you notice that your allergies or asthma have worsened, and you do not know the reason, it is very likely that it is dust mites that feed on dead skin cells and other allergens that are in the mattress. Since you spend huge part of the day sleeping, then you are exposed to allergens during that time and your problems will get worse. Vacuuming the mattress should help as well as mattress protector, but when the mattress is old, then it is impossible to eradicate dust mites and you have to order a new one. Also, try to find a mattress made of bamboo material, which is naturally hypoallergenic.

    Muscle stiffness & joint pain

    When you wake up in the morning, you should feel rested and ready for the day, not stiff and in pain. When your mattress is not comfortable, your muscles and whole body will suffer.

    You will feel pain in your neck, spine and other parts of your body, and your muscles will be so stiff that even stretching will not help. It has been proven that a new mattress can reduce back pain and other problems with bones, joints, tendons and muscles.

    Squeaky springs

    Noisy springs can be a problem you face since the day one when you buy a cheaper innerspring or even a hybrid mattress. If the springs are noisy from the beginning, then this is not a sign of deterioration of the mattress.

    But if your mattress was completely quite for years, and now you’re starting to hear springs when you turn around, that’s definitely a warning sign. That is sing of fabric pockets damage or the springs are worn out. In either case, a new mattress is necessary.

    Will my mattress last longer if I flip it often?

    As we mentioned rotating and flipping can be very helpful and extend the mattress lifespan. If you have a two-sided mattress then it is recommended that you flip and rotate mattress regularly, every 6 months. If it is single-sided, then just rotate it. Memory foam and innerspring mattresses should be rotated and flipped more often than latex mattress.

    The most important thing is that as soon as you notice that your mattress is not as comfortable as before and that the quality of your sleep has deteriorated, buy a new mattress immediately, because without a suitable mattress you will not be able to sleep. And if you can’t sleep, it will have far-reaching consequences for your physical and mental health. Insomnia can cause depression and anxiety, and then it is a vicious circle from which it is difficult to get out. Also, back problems will occur and you will constantly feel a lack of energy.
