Everything has its expiration date and the mattress is no exception.

But how often should you change your mattress?

Well, mattresses need to be changed every 7-10 years. However, you may want to upgrade your bed sooner if it’s become uneven, saggy, if the springs poke you, or if you constantly get allergies!

If you want to know what’s the connection between these factors, scroll down and read all the answers below!

What Impacts the Lifespan of Your Mattress?

First thing first, let’s figure out which things have an impact on how often should you change your mattress:

  • Quality. The quality of the materials will directly impact your mattress lifespan. Cheaper beds are made of less durable materials: more porous foams, thinner coils, synthetic latex instead of natural, etc. They typically have a 1-2 year shorter lifespan that you’d normally expect. For example, if an average innerspring mattress lasts for 7 years, you can subtract 2 years in case you’re buying a cheaper bed.
  • Climate. Weather conditions can also impact your mattress longevity. This mainly applies to humid regions because the moisture is the main enemy of the mattress, especially if it’s made of foams. Memory foam can absorb moisture from the air, which can lead to mould growth and can be dangerous not only for the mattress but also for your health (1). So, if you live in a humid area, be sure to encase your mattress into a waterproof mattress protector and get the bed base with good under-bed aeration.
  • Pets. Another reason that can make you want to replace your mattress is allowing your pets to sleep on the bed. Pet hair and skin particles can accumulate into the mattress layers and lead to allergies. Plus, some gods or cats can chew or scratch the mattress, which isn’t good for its longevity too.

The Main Signs Your Mattress Needs Replacement

Now, you might be living in a region with high humidity and sleeping with three dogs in the bed every night but your mattress seems okay.

That’s totally normal, as the wear and tear happen gradually.

But you can still track these changes and find out if you need to buy a new mattress.

Here’s what to look for:

  • It takes you longer to fall asleep. When a mattress is new, it adapts to your adopted position pretty quickly, so you spend less time getting comfortable and falling asleep. But when the mattress wears out, its upper layers go flat, and you feel a more rigid base which isn’t so pliable to your body shape. So if you noticed that you toss and turn more than usual to find a comfortable position, this might be the sign that your mattress needs changing.
  • You wake up with morning pain. This is connected to the previous point. See, when you spend more time to find a comfortable position, it may result in adopting an awkward one that can strain your back muscles. Plus, an older mattress typically has an uneven surface with saggy spots and indentations, and they cannot support the neutral spine alignment.
  • You have congestions and puffy eyes. This might sound counterintuitive but actually, your mattress can accumulate millions of dust and debris particles over the years, and these particles can become the food for dust mites (2). Dust mites are the most common allergen in the world, and if you’re sensitive to them, you might develop allergies or even asthma.

With that being said, if you noticed that each of your mornings is accompanied by puffy eyes or low back pain, and it takes you longer than usual to fall asleep — maybe these are the signs that your mattress needs replacement.

How Often Should You Change Your Mattress?

The final factor that impacts the lifespan of your mattress — and the one you pay attention to when choosing a new bed — is its type. There are four mattress types: foam, latex, hybrid, and innerspring, and each of them has its own estimated lifespan.

So, let’s see how long your mattress will last, depending on its type.

Foam Mattresses

Both memory foam and polyfoam mattresses fall into this category but they have some subtle differences in terms of lifespan.

So, an average memory foam mattress will generally last you 8-10 years before wearing out completely. The main issues of the aging memory foam bed are saggy edges, indentations, odours, and mould and mildew growth. You can prevent or slow down these issues by rotating your mattress every 3-6 months and encasing it in a mattress protector.

As for polyfoam, this is usually a cheaper alternative to a traditional memory foam mattress. Polyfoam is more porous and less resilient, so it can go flat sooner, in about 7-8 years.

Latex Mattresses

The good news here:

With a latex mattress, the question “How long to keep a mattress?” might not even arise.

See, latex mattresses are considered the most long-lasting among other types. they can serve you for 15 years, and some high-end models even claim a 20-year lifespan.

So the chances are that you will want to replace your mattress rather our of boredom than because of actual wear and tear.

But what’s the secret?

Well, the latex, despite having an open-cell structure, is pretty dense and has a quick rebound. The latter means that it bounces back to its initial shape after you remove the pressure, unlike memory foam that takes some time to expand. These properties make the latex more long-lasting.

Plus, natural latex is immune to mould and dust mites, which also adds some scores to its durability.

Innerspring Mattresses

Traditional innerspring beds have a relatively simple structure: a coil unit core and a thin layer of foam or pillow-top above. But despite their simplicity, innerspring mattresses are no worse than other types and will serve you for 7-8 years with ease. 

Also, many innerspring beds are made to be flippable which makes it easier to make the most of their use.

Hybrid Mattresses

Hybrid mattresses typically have a coil core with different foam or latex comfort layers. This is a combination that many users find the most comfortable among all the mattress types.

But this is where the things get tricky:

Hybrid mattresses are the newest mattress type. And while most of the manufacturers claim that their hybrid beds can last up to 10 years, there isn’t too much data on their longevity. Plus, the lifespan of the mattress can fluctuate depending on the materials and their combination. So it’s better to check out the signs of wear and tear and rely on your feelings.

Summary

Now you know everything about the mattress lifespan and can choose the bed depending on your demands. Note that the average mattress will serve you for at least 7 years but you can slow down the wear and tear by rotating it, encasing it in a mattress protector, or flipping it (if the manufacturer allows for that).
