What?! Why? Do I even need to?

So many people in the world believe that a mattress is a one-time investment but they could not be more wrong. Think of it. Mattress is the most-used furniture in any house and we spend 1/3rd of our lives sleeping on it. So to expect it to last a lifetime is possible only in dreams! Typically, you should replace your mattress every 8 to 10 years because most mattresses tend to become ineffective beyond that.

Here’s the average lifespan of mattresses

But the lifespan of a mattress can vary vastly depending on its type, construction and how it was maintained all this while. So it’s wise to judge your mattress on more than one sign.

11 Tell-Tale Signs You Should Replace Your Mattress

  1. If you wake up feeling stiff, sore, achy and tired even after clocking 8 hours of sleep, your mattress is not working any more.
  2. If you are napping soundly on sofas and hotel beds than on your mattress of four years, it’s not a good sign.
  3. If you are tossing and turning in bed all night and even your favourite sleep position isn’t helping, then something has changed about your mattress. It isn’t supporting your spine like it used to and this can lead to back pain.
  4. If you are rolling to the center of the bed center in your sleep or you feel your mattress is caving in, the core of the mattress has lost its structural durability.
  5. If your mattress sags or dips as you sleep and sit on it, it’s worn out. Either the springs have broken down or the foam has softened. Saggy mattresses can cause pain as they fail to cushion the body.
  6. Tears, hols, worn edges, stains, dust and lumps are obvious signs that your mattress is well past its prime.
  7. If your sleep gets disturbed as your partner moves in and out of bed, your mattress isn’t absorbing motion transfer and needs to be replaced.
  8. If you find yourself coughing and wheezing as you hit the bed at night or after you wake up, chances are dust mites and other allergens have made your mattress their home.
  9. If you have gained weight or lost many kilos, your good ol’ mattress might not cradle you the way it used to. Which sadly means, it must go.
  10. Likewise, if you have added a bedmate to your life recently, you will have to swap your old mattress with something that’s compatible for the both of you.
  11. Lastly, if your mattress has served you for an average of 8 years, it’s time to part with it. It’s another thing that hardly any of us recall when we bought it!

Pro tip: The next time you get a new mattress, please write down the date and year of purchase somewhere. Because why mess with sleep?

when to get a new mattress

Above all, a new mattress can improve sleep

2007 research at Oklahoma State University analysed the impact of new bedding and it reported significant improvements in participants’ sleep.

  • 64.40% reported improved sleep quality
  • 69.60% reported improved sleep comfort
  • 62.80% reported reduced lower back pain
  • 58.40% reported reduced back stiffness

So even if your mattress hasn’t reached its ‘expiry’ yet, it’s definitely worth switching to a new mattress – it might help you sleep a whole lot better.

Check Warranty

If mattresses can last for 8 to 10 years, then why do mattress companies give 15 to 20 years of warranty?

That’s exactly where the confusion lies. Mattress warranty is not as same as the durability of the mattress or its lifespan. So let’s see what these terms mean:

  • Mattress warranty covers the structural damages incurred by the product.
  • Mattress durability refers to a mattress’s ability to resist force exerted on it.
  • Mattress lifespan/life expectancy refers to how long a mattress can maintain its original comfort and support and this depends on how well it’s built, how often you use it, how you care for it, etc. In most cases, mattress warranties tend to outlive the mattresses.

Pro tip: If your mattress hasn’t expired but has only suffered damages, check if it’s still under warranty and get it fixed instead of throwing it at once. 

There are two kinds of warranty. Know them.

  • Warranty against defects: This is a written warranty that the manufacturer gives you to repair or replace a damaged mattress under terms and conditions.
  • Consumer guarantee: This one is ensured by Australian Consumer Law (ACL) and it promises that the product functions the way it’s advertised by the seller.

But if you have made up your mind to get rid of the old mattress, why don’t you do it the eco-friendly way. Yes, that’s possible. Read about it here.
