How Often Should You Replace Your Mattress?

You spend about a third of your life in bed, so your mattress plays an important part in your health and well-being. That’s why it’s important to have the right type of mattress that will provide you with the most comfortable sleep. On top of that, it’s also important to know when to replace that mattress since nothing lasts forever. So, how often should you replace your mattress?

According to the National Sleep Foundation, mattresses have an average lifespan of 8 years. However, there’s no set rule and it all depends on the type of mattress you have, its quality, how you care for it and how you sleep. For example, high quality mattresses, with good care, can last 15 years or more. Cheaper and lower quality ones might last just about 5 years.

Mattress Lifespan According to Its Type

These mattresses are made with inner steel coil springs and layers of various foams or fibers. Typically, they last about 7-10 years. Will they last longer or shorter depends on the spring construction. The more resilient the coils and the denser the padding, the longer it will last.

Another factor affecting the longevity is the weight of those sleeping on them. Heavy sleepers cause more wear and tear.

Memory Foam

Memory foam mattresses are made from polyurethane material that offers the ability to conform to the sleeper’s body.

Unlike spring mattress, memory foam ones don’t have any mechanical parts that can break down. A high quality memory foam mattress can last about 10 to 15 years. Some might last even longer.

To keep it longer in its best form, you might need to turn the mattress head to foot. This will help to distribute the wear and tear.


This type of mattress uses natural or synthetic latex foam. The material makes it very hard and also very durable. You can expect a lifespan of about 15 years and more.

Why Replace Your Mattress?

There are various good reasons to buy a new mattress when your old one has lost its prime condition.

First of all, having to bear your body weight through multiple nights eventually causes the mattress to lose its shape. It can start to sag and it can create lumps. Due to this, instead of providing adequate support, the mattress will provide you with uncomfortable, sleepless nights.

Secondly, mattresses tend to accumulate dust mites and other allergens. This happens due to your body shedding hair, dead skin cells and body oil. Eventually, this can create a breeding ground for dust mites. And if a person sleeping on the mattress has allergies or any respiratory condition, this can cause symptoms.

Signs That It’s Time For a Replacement

Wear And Tear

If you see visible lumps or sagging in the mattress or if you can feel the bed springs when you lie down, it’s time to get a new one. Also, the same goes for a noisy mattress. If you can hear the springs creaking and groaning all night long, then it’s most likely past its prime condition.

It Becomes Uncomfortable

why replace your mattress

A mattress, together with a pillow, is supposed to provide support for your body, helping to properly align your spine while you sleep. But if the mattress is worn out and has lumps or it feels flattened and uneven in places, this means that it’s not providing proper support and aligning. This can result in poor sleep and in some cases, it can cause body aches and pains.

Sleepless nights can contribute to chronic neck and back pain. If you experience pain or stiffness every morning when you wake up, it can be a sign that you have an old mattress or one of poor quality.

You can try first flipping or rotating the mattress. However, if it still doesn’t feel comfortable, it might be time for a new one.

Allergy or Asthma Symptoms

Even the cleanest beds with time accumulate dust mites. This can cause allergic reactions and asthma attacks.

There are a few things you can do to ease your symptoms. First of all, you could use a protective, allergy-reducing cover. And secondly, regularly vacuuming and steaming could also help to prevent the accumulation of dust and mites in your mattress.

  • Make sure that your kids don’t jump on the bed as this can damage the coils or can cause dents in foam.
  • Rotate your mattress head to feet every 3-6 months, which will allow it to wear out more evenly.
  • If your mattress is flippable, do it every 6 months or so.
  • Regularly clean the mattress according to the instructions provided by the manufacturer.
  • Use a mattress protector, which will help to keep the dust and debris away.
  • Make sure that your mattress has a proper foundation with even distribution of weight.

Getting a new mattress will help you get better sleep and you won’t be waking up with any stiffness or allergy symptoms.
