How Often Should You Buy a New Mattress?

Let’s say you sleep in your bed for 8 hours a night for 365 days straight. At the end of the year, you have spent almost 3,000 hours lying on your mattress. Considering how much time you spend sleeping (plus lounging) on your mattress, it’s not surprising that it wears out eventually. The harder question is – how long does it take before a mattress really needs replacement?

The answer depends on a lot of factors: the mattress quality, the amount you sleep, your sleep style, whether you sleep with a partner, etc. The National Sleep Foundation recommends changing your mattress every eight years, but some mattresses will last longer than this (and some will last shorter). Ultimately, it’s up to you to decide when your mattress needs replacement.

After all, you know your mattress and what kind of sleep it delivers better than anyone. But you also use your mattress every night and have grown used to its flaws and defects. Lots of people are sleeping on worn-out mattresses that hurt (not help) their sleep simply because it feels familiar.

You don’t want to fall into this trap yourself. You also don’t want to replace your mattresses before it’s actually necessary. Watch out for these signs that suggest it’s time for a new mattress:

  • Dips and Depressions – Your mattresses are supposed to provide a flat sleeping surface with even amounts of support. If there are obvious sections where the mattresses is sagging – most likely around pressure points in your shoulders and hips – it means your mattress no longer provides adequate support. At best, this makes your mattresses less comfortable, and at worst it leaves you with pain in the morning. Either way, saggy mattresses need replacement.
  • A Permanent Outline – If you have a memory foam mattress, you’re familiar with how the impression of your body stays in the foam for a second or two after you get out of bed, then it springs back to flat. As the years go by, the foam takes longer to fill back in, and eventually you’re left with a permanent outline of your body in bed. This is a clear indicator that the memory foam is worn out, incapable of providing adequate support, and in need of replacement.
  • Spinal Pain – No matter how old your mattress is, when it doesn’t provide enough spinal support it’s not worth holding on to. If you sleep on your back or stomach, your spine should naturally form an S shape. If your spine is flattened or the S is elongated, the mattresses aren’t doing you any favors. Side sleepers should have a straight spine, but a worn-out mattresses can cause uncomfortable bending and flexing. Spinal pain starts as a morning annoyance, but it can quickly become a chronic condition, so it’s worth seeking out a new mattress ASAP.
  • Lumps and Bumps – Over years of use, the padding inside your mattress will begin to shift around no matter what kind of mattress you have. Lumps can start to form, meaning that padding that’s supposed to provide you with support has moved to other parts of the mattress. On top of that, trying to sleep on an uneven sleeping surface is annoying. Investing in a new mattress gives you an optimal environment to get the sleep you need.
  • Allergy Flare-Ups – So far, we have mostly focused on how mattresses lose padding and support, but that’s not the only consequence of age. Allergens like mold, mildew, and dust mites collect in the mattress too. Unless you’re diligent about cleaning the mattress (not just the sheets) those allergens could reach high enough concentrations to cause respiratory issues or other allergic flare-ups. Your bed is supposed to help you relax, not make you sick, so if your allergies are bothering you unexpectedly, consider a fresh mattress.
  • Restless Nights – If you have trouble getting to sleep and staying asleep, your mattress is the first thing to investigate. Lots of factors affect your sleep, from your pillows to the temperature of the room, but none matter more than the mattress beneath you. Even if you can’t identify a specific problem, the fact that you’re consistently not sleeping well indicates that something is wrong with your current mattress. For the sake of your health and wellbeing, start looking for a mattress that encourages you to sleep deeply.
  • Crowded Conditions – You can also outgrow a mattress. Perhaps you move into a bigger bedroom, start sharing your bed with a partner, or need a better sleeping surface because of pregnancy. Your sleep is too important to try and make do with a bed that no longer works for your sleeping arrangements. The sooner you make an upgrade, the sooner you can sleep how you want.
  • Advancing Age – The best time to replace a mattress is before it’s absolutely necessary. If your mattress is 7-10 years old it may still perform perfectly, but statistics suggest it’s reaching the end of its lifespan. Instead of waiting until you start tossing and turning at night or waking up with aches and pains, begin looking at new mattresses – many of which offer features and amenities that were not available last time you went mattress shopping.
