How Long Does a Memory Foam Mattress Last?

A memory foam mattress can last between 10 and 15 years if you take care of it well. These mattresses last much longer than others because of the unique memory foam material, which springs back to its original shape after you’ve been sleeping on it.

How do I know when my memory foam mattress is worn out?

You might need to replace your memory foam mattress sooner if it feels worn out. This depends on the mattress quality, how well it’s been cared for and how often it’s used. You also might need a new mattress if your body has changed over time, such as your weight or any new health issues which you need extra support for.

It’s important that you don’t wait until your memory foam mattress feels uncomfortable to sleep on before you replace it. Here are five things to look out for to see if your mattress needs replacing.

5 signs that your memory foam mattress should be replaced

1. Sagging or sinking

Memory foam is designed to respond to heat and pressure, moulding to the shape of your body. When the pressure is removed and you’re no longer lying on your mattress, the material gradually springs back to its original shape.

While a memory foam mattress is less likely to sag or sink when compared to a regular mattress, it still can happen, especially if you have a cheaper or lower-quality version. If there is a visible sag or indentation in your memory foam mattress where you have been sleeping, it’s time to replace it.

2. Wear and tear

Signs of wear and tear, such as your mattress feeling lumpy or making a creaking sound, would suggest that you need a new one. Other visible wear and tear like stains or unpleasant smells are also good signs that you should replace your mattress.

3. Waking up tired and sore

If your memory foam mattress needs replacing, it could affect your sleep quality. If you wake up still feeling tired, it could be because your mattress is no longer as comfortable and it’s impacting your sleep. For the same reason, you could experience aches and pains caused by an old mattress if it’s not supporting your body as well as it should be.

4. You can feel your partner moving

Memory foam is an absorbent material which helps to lessen the impact of your partner tossing and turning in bed. If they wake you up by moving around at night, or vice versa, your memory foam mattress may be less absorbent and may need to be changed.

5. Feels uncomfortable

If you find your old memory foam mattress is becoming uncomfortable to lie on, it’s likely time to replace it. It’s best if you can try to avoid waiting until this happens and invest in a new mattress before it causes discomfort.
