How old is your mattress? Unfortunately, there are not many people who can accurately answer that question. We often don’t even think about the lifespan of our mattress - even though we spend thousands of hours on it!

A good night’s rest is mandatory if you want to have a good day - and, for this, you need to have a good mattress. But sleeping on an old, worn-out, or poor-quality mattress can have negative side effects.

How Long Should a Mattress Last?


Most mattresses should last between 7 and 10 years. However, there are many variables that can influence mattress lifespan.

The original build quality of the mattress, the materials used, and even the weight and sleeping styles of the sleepers can all influence a bed’s longevity.

For example, a natural latex mattress or a very high-density memory foam mattress will last much longer than a standard spring or cold foam mattress. 

Heavier-weight people will also need to change their mattress more regularly. This is because the mattress will wear out more quickly and won’t be able to support the body as well. To avoid back pain, we recommend larger-built people change their mattress every 7 years.

Of course, mattresses don’t have an explicit “expiration date.” It’s up to the individual to decide when it’s time for a new bed. 

Signs of a bad mattress

A worn mattress tends to sag in the centre. When you lie down, you’ll feel dents in your hip and back areas.

You may also wake up with lower back pain or stiff muscles. It is likely that your mattress no longer provides enough support to keep your spine aligned. A good mattress should help maintain healthy alignment of the spine by keeping it in a relatively straight, natural line. When your mattress ages, the material will sag and you’ll sink in more deeply, which misaligns your spine. If you’re feeling this so-called hammock effect, then it’s time to change your mattress to avoid pains and sleepless nights.


Another sign of a bad mattress is visible distortion. To find out if your mattress has lost its shape, you can use a measuring tape to check for visible sagging areas.

Older mattresses also cause more severe allergies. Dust, dust mites, pollen, and mould accumulate in your mattress over the years, and this is more pronounced in older mattresses. As a result, you may experience itchy eyes, rashes, and even difficulty breathing. Even if you have a mattress that’s specifically designed for allergy sufferers, you’ll risk reacting if the mattress is too old.


Checklist of the top signs indicating a bad mattress

1. Your mattress is over 8 years old
2. You don’t feel rested when you wake
3. You wake up with aches and pains and holding your back
4. Other places feel more comfortable
5.Your spring mattress squeaks or your box spring creaks
6. You have a visible and noticeable sag
7. You hammock into the mattress
8. You are suffering from bad dust allergies
9. You have experienced a significant change in weight

Why and when should you change your mattress?


A new mattress can do wonders for your sleep. A high-quality mattress will be comfortable to lie on but firm enough to support your body, keep your spine straight, and release pressure points. You’ll get a good night’s sleep and wake up feeling refreshed.

If you’ve noticed any of the previously mentioned signs of a bad mattress, then it may be time to invest in a new one. Also, pay attention to the following:

  • Do you feel the springs of your spring mattress?
  • Do you feel the slats of your box spring?
  • Does your mattress contain bumps and dents?
  • Is your mattress squeaky?

If you’ve answered yes to any of these questions, then your mattress (and possibly box spring) are worn out.

Need another way of telling if it’s your box spring? Press down on a part of the box spring that is normally under pressure (like where your hips or shoulders lie). Then press down on another part that is usually under less pressure (like where your feet are). If there is a difference in flexibility and resistance, then you need to change your box spring.


The comfort and support of our mattress is vital to the quality of our sleep. Even though mattresses can be a significant expense, it’s absolutely worthwhile to replace them regularly.

Sleep is one of the most important aspects of human health. Without quality sleep, our bodies are not able to heal and rejuvenate themselves, and our brains struggle to process emotions and store memories. 

Get the mattress that gives all the support you need for ultimate sleep experience.
