When To Replace Memory Foam Mattress

There will come a time when your memory foam mattress will wear out. If you’re now thinking about whether or not to change your memory foam mattress, it’s likely time to do so.

Typically a foam mattress lasts about eight years. However, noisy springs, wear and tear, constantly experiencing allergies and asthma, and feeling stiff muscles may indicate that you should replace your mattress.

The Many Reasons To Replace Your Memory Foam Mattress

Noisy Springs

One of the main parts of a mattress is the springs. It is responsible for holding the foams together to make it more conducive for sleeping. If a mattress’s inner springs start to make sounds, it is a sign that they are wearing out. 

Allergies And Asthma

Small insects like dust mites and bed bugs are allergens that can trigger allergic reactions from those prone to allergies and asthma.

While you may be replacing your bed sheets and cleaning your room regularly, it may not be enough to remove all allergens that might be present in your mattress. If your allergies worsen, try to see if the cause is your mattress.

Wear And Tear

It’s normal for any daily use item to wear out over time. This process determines the value of the item. 

If you see your mattress starting to have deformed lumps or misplaced coils, it may be a sign that you need to change your mattress. Coils may even poke the outermost layer of the bed, making it painful for those using the mattress.

Muscle Stiffness

If a mattress starts to become less comfortable and deformed, it will not be able to support your body in your sleep as per its purpose. When this happens, you will often feel pain in your back, legs, and even hips.

Another factor to consider is the constant weight of pressure put on the mattress. As for any other home item that people use, mattresses depreciate over time. It’s just a matter of how soon it happens. 

The weight of a person or people using the mattress can affect whether it will quickly become worn out or not. If, for example, two people use a single-sized bed at once, there’s a higher chance of faster depreciation on the mattress (learn my tips for when to replace other types here).
