How Old is Your Mattress?

Generally, you need to replace a mattress that is 7-10 years old. Over time, mattresses lose their ability to provide proper support and comfort due to wear and tear. If you’re not certain how old your mattress is, consider these other factors as well.

You’re Experiencing Pain or Discomfort

If you consistently wake up with aches, pains, or stiffness, it could be a sign that your mattress is no longer providing the support your body needs. How your body responds to sleeping on the mattress is one of the best indicators of when it is time to replace your mattress, listen to it!

Sagging or Indentations

If you notice visible sagging or body indentations in your mattress, it’s a clear sign that the support layers have worn out. This can lead to poor spinal alignment and discomfort.

Most times a sag or indent in the mattress is easily identifiable upon visual inspection. However, if you’re not 100% certain of a sag, try placing a marble on the mattress to see if it rolls due to gravity. If you see movement, you’ve got a sag!

Lumps and Bumps

Uneven or lumpy areas on the mattress surface indicate that the internal materials are deteriorating and can no longer provide a uniform sleeping surface. So much so that sleeping on the couch might seem like a better option! Lumps in a mattress can cause pain and discomfort.

Restless Sleep

If you’re tossing and turning more than usual during the night, your mattress might not be providing the comfort you need for a good night’s sleep. The average adult requires 7 or more hours of sleep each night to achieve enough sleep for good health according to this article from The Mayo Clinic.

If you’re waking up because something is out of whack and you have to adjust positions, or maybe you need to make some adjustments to the bed itself, then it is absolutely time for a new mattress! Your body is smarter than your mind in this case, listen to what your body is telling you!

Allergies or Asthma

Over time, mattresses can accumulate dust mites, allergens, and even mold. If you’re experiencing increased allergies or respiratory issues, it might be time for a new mattress.

Allergens are going to make it miserable for you to sleep, particularly when the source is your old mattress. A new mattress will certainly help with this issue. Plus, there are new hypoallergenic options that are available!

Noise & Motion Transfer

If your mattress creaks, or squeaks, it could be a sign of deteriorating materials or a lack of proper support. Mattresses are obviously not meant to make any noise, so if you’re hearing a lot of strange sounds coming from your old mattress, it’s time to shop for a new one!

Motion transfer happens when your sleep partner or your pet moves around and those movements jostle you around disturbing your sleep. Modern mattresses are designed to virtually eliminate all motion transfer so a new one would certainly remove this sleep deterrent.

A Change in Lifestyle or Body

If your body weight or sleep preferences have changed, your current mattress might no longer be suitable for your needs. For example, if you’ve gained or lost a significant amount of weight, or if you now have different sleep preferences, it might be time to consider a new mattress.

Visible Wear & Tear

If you see visible signs of wear, such as frayed edges, exposed springs, or fabric damage, it’s an indication that your mattress has seen better days. Actual damage is an obvious sign that it’s time to replace that old mattress with a new one that will allow you to get a better night’s sleep.

Lack of Support

Your body needs to be properly supported while you sleep. That is the whole point of a mattress! When you lie down on your mattress, if you feel like you’re sinking too far or not getting the support you need, it’s a sign that the materials have likely worn out. Replace that old mattress!
