The quality of life depends on the quality of sleep. A mattress is an important attribute of a healthy sleep.

American researchers found that buying a new mattress noticeably improves sleep. But how to know when it is necessary to change the mattress? And how often should it be done? Let’s answer these and other questions.

How often should you change your mattress: what is the life span and what does it depend on?

No one will tell you the exact figure. All because the life of the mattress is affected by several factors. For example:

  • the quality of the mattress;
  • the materials used;
  • the weight of the sleeper;
  • the posture of the person during sleep.

To understand that you need to buy a new mattress, you can buy the signs, which we will write about below. But this sleeping attribute has an average lifespan that you should focus on. According to the National Sleep Foundation (USA), the lifespan of most mattresses is 7-10 years.

Experts from the same foundation evaluated the average lifespan of popular types of mattresses. Products with latex filling last the longest.

How to know when it’s time to change your mattress: 7 signs

Of course, if your mattress is 8 or more years old, you should it. But since the lifespan of mattresses depends on several factors, the quality of your sleep remains the key indicator. The National Sleep Foundation recommends replacing your mattress in the following cases.

1. You’ve stopped getting enough sleep. You may have noticed that you sleep better in hotels or visiting than you do at home.

2. You feel the mattress is sagging. For example, dents may have formed in the middle, causing the sleeper to roll toward the center.

3. Waking up with a pain in the body. One cause of morning discomfort can be just dents in the mattress. Because of them, the bed attribute does not provide enough support for a comfortable sleep.

4. You or your partner toss and turn in bed all night or can not find a comfortable position for a long time.

5. Allergy or asthma symptoms have increased. Dust mites and allergens accumulate in the mattress. If vacuuming and regular cleaning, don’t help improve the situation, it’s time to think about buying a new mattress.

6. You have felt your partner’s movements at night more than before. For example, if your roommate rolls over, a wave goes all over the bed and you wake up.

7. The mattress has creaked. This may show that the springs are worn out and no longer properly support your body.

If the above symptoms of mattress death do not suit you, it is probably ready to guard your healthy sleep for a few more years.

What happens if you don’t change your mattress: health implications?

An old mattress is one probable cause of restless sleep. Poor sleep worsens the quality of life, at least because it causes several diseases.

For example, lack of sleep can be associated with diabetes, high blood pressure, cardiovascular disease, coronary artery disease, obesity and so on.

Dust mites are also worth mentioning separately. Beds are their prime habitat. Hundreds of thousands of dust mites can live in bedding, including the mattress. They feed on dead bits of epidermis that a person loses every night.

Dust mites and their products contribute to allergic reactions such as allergic rhinitis, respiratory allergosis, bronchial asthma, atopic dermatitis, conjunctivitis.

It is unlikely to completely rid the house of these insects, but you can control their numbers by changing the mattress in time.

How to prolong the life of a mattress

Proper and careful use of the mattress will preserve its original appearance for a long time and help to prolong its service life. Here are a few tips.

  • Use a mattress cover. This is a cover for the mattress. It will protect the product from dust, moisture, the spread of mold spores or from the claws of the cat.
  • Clean your mattress according to the manufacturer’s recommendations. This way you can reduce the risk of dust mites.
  • Ventilate your bedroom regularly to reduce dust and moisture concentrations. Sometimes you can remove the sheets and mattress cover while airing to refresh the mattress itself.
  • Try to keep the mattress away from pets to reduce the risk of damage to the product.
  • Do not allow children to jump on the bed to avoid different disturbances in the mattress's construction.

Does your mattress need to be flipped?

Experts from the National Sleep Foundation recommend studying the instructions that come with the mattress. It should tell you whether you can flip the mattress.

Should I do it at all, even if the instructions say to change sides? Yes, you should. This way you can evenly distribute the wear and tear of the mattress, thereby prolonging the life of the product.


The average person spends 26 years of his life sleeping. It turns out that on average we spend 33 years in bed. But old mattresses not only reduce the benefits of sleep but also increase the risk of negative health consequences.

A mattress is an important component of a healthy sleep. You should not skimp on it or neglect to replace it.
