Maybe it’s been a while since you’ve bought your mattress or your bed is now sagging. You might be questioning if your mattress’ is in its last years already. But how long does a mattress last?

Even the most expensive mattress is bound to degrade its quality over time. And when it does, it is important that you know if it’s time to replace your mattress already. A good quality mattress will dictate whether you will have a good night’s sleep, which also affects a person’s overall health and wellbeing. In fact, in a 2020 consumer report1 by Better Sleep Council and International Sleep Products Association, millennials rate “a good night’s sleep” as the most important factor in overall health and wellbeing.

In this blog, we will discuss how long different types of mattresses last, factors influencing a mattress’ lifespan, and signs to check if you need a new mattress already.

How Long Does a Mattress Last?

According to Better Sleep Council, most mattresses have an average lifespan of 7 years3. But different types of mattresses have different lifespans. Based on more than 25,500 mattress owners’ experience2, air mattress and latex mattress lasts the longest at about 8 years of lifespan.

On the other hand, futon mattresses last the shortest.

Why do the air mattress and latex mattress types last the longest? Let’s analyze:

  • An air mattress is made up of latex and filled with air for the structure. The only damages an air mattress can have are holes or lacerations which can be fixed easily. Here’s how you can patch a hole in an air mattress.
  • A latex mattress is made up of natural materials which contribute to its durability. Because of its compact structure, latex mattresses have a natural resistance to mould and dust mites. You can learn more about what is a latex mattress here.

Following the study of more than 25,500 mattress owners2, we can observe that the average lifespan is aligned with its price. This is because most of the time, a good quality mattress means a higher price because of the materials used for that specific type.

Mattress Type

Average Lifespan

Price (based on average model)

Futon mattress

5 years

Under £400

Innerspring mattress

6 years

£400 to £800

Foam mattress

6 years

£400 to £800

Hybrid mattress

7 years

More than £1600

Memory foam mattress

7 years

£800 to £1600

Latex mattress

8 years

£800 to £1600

Air mattress

8 years

More than £1600

But price and types of mattress are not the only factors that affect the lifespan of a mattress.

Factors Influencing Mattress Lifespan

Now that we know how long different types of mattresses usually last, that doesn’t mean you can reach that period.

  • Can a mattress last 20 years? Even if the average lifespan is 7 years, it can last 20 years if the mattress is properly taken care of.
  • Can a mattress last 7 years? Even if the warranty period is 10 years, it may not last 7 years if the mattress is heavily used.

Different factors influence the lifespan of a mattress and these include:

  • Mattress quality

When we buy a mattress, the price would most of the time be dependent on the quality of the mattress. For example, based on what has been discussed previously, a futon mattress would cost the cheapest but it would still wear out the fastest.

This also applies to the different densities of a foam mattress, the higher the density is, the more expensive it is, and the more durable it is. A higher density mattress can resist weights and compressions applied on the mattress.

On the other hand, lower density mattresses would have the tendency to sag over time because of compressions.

  • Mattress type

As discussed previously, air bed and latex mattresses last the longest while futon beds last the shortest. This is due to the materials they are made of the manner of use for each type.

  • Weight of sleeper

Mattress owners who weigh more than 100kg, for example, will need to replace their mattress more frequently due to the heavy stress exerted on the mattress. Sleepers who are lightweight, on the other hand, will not impose heavy stress on the mattress.

  • Frequency of use

Whether you’re the type to stay in bed all day long or just use the bed on weekends will affect if your mattress will sag or lose its quality early on.

  • Care and cleaning routine

If a mattress is properly taken care of, meaning

  • Cleaned regularly
  • Changed beddings regularly
  • Vacuum cleaned regularly
  • Has proper ventilation
  • Has appropriate bed frame
  • Not jumped on or subjected to heavy wear and tear

It would most probably last beyond its warranty period. But if it’s the opposite, dirt, stains, and damage will take a toll on your mattress.

How Can You Tell if You Need a New Mattress?

How often should a mattress be replaced is not just dependent on the typical lifespan of a mattress or the warranty period of a mattress. It should depend on the user’s comfortability. A 2020 consumer report1 by Better Sleep Council and International Sleep Products Association shows that most mattress buyers started to shop for new mattresses because of issues with their old mattresses. The most common issues that triggered buyers to look for a new mattress include

  • previous mattress being too old
  • previous mattress not providing a good night’s sleep
  • previous mattress sagging

So, when should you change your mattress? How can you tell if it’s time to say goodbye? Aside from the age of your mattress, being more than 7 years of age, these are some of the signs you should look out for:

  • You are not sleeping well.

If you’re not sleeping well, this can affect your overall health4. Short-term sleep deprivation can impair judgment, mood, and cognitive performance.

On the other hand, chronic sleep deprivation can lead to obesity, diabetes, cardiovascular disease, and even premature death.

  • You sleep better in other places like hotels, couches, and other beds.

If you’re sleeping better on other beds, it means your mattress is the cause of your sleeping problems.

  • Your mattress is sagging and you wake up with back pain

A sagging mattress can cause back pain because the spine is not aligned when sleeping. You might think you can fix this, but how do you fix a sunken mattress? Well, you can try adding pads to the centre of the mattress, but this won’t be as comfortable as a new mattress.

  • Your mattress is lumpy and you wake up with body aches.

If you only sleep on a particular area of the bed, it might create lumps on other parts of the bed because of uneven use. Your mattress might have developed lumps because of irregular rotation or flipping.

  • You sink onto the bed.

If you sink on the bed, it means that it is not firm enough to give you the support you need. The materials of the mattress may have deteriorated already because of heavy use. For example, if you have children who are always jumping on the bed, this can cause damage to the spring.

  • You’re having allergies when in bed.

Dust and dirt like fur, hair, and dead skin are common allergens that can be found in your mattress. While regular cleaning can get rid of these on the surface, dust and dirt may have deeply infiltrated your mattress especially if it is old and not been taken care of for a long time.

  • Your mattress has grown moulds.

Moulds can develop in a moist and humid environment, especially if your bedroom is not properly ventilated. While you can clean moulds on the surface, if it has deeply developed on the core of your mattress, there’s nothing we can do.

  • Your mattress has a bed bugs infestation.

Should you get a new mattress if you have bed bugs? Definitely, yes! Bed bugs can take time to get rid of. If you’re suffering from bed bugs, you can check this blog for guidance on getting rid of bed bugs on mattresses.

If you relate to one of the situations above, it’s time to get a new mattress. You can check out our guides to have a deeper knowledge of what types of mattresses are best for you.
