When To Replace Your Mattress And Box Spring

In general, you must replace your mattress and box spring at the same time. This is especially true if you got them together and the manufacturer recommends using a box spring with their mattress. However, there is an exception with this timing if you got your box spring and mattress separately. 

Considering that the average lifespan of a mattress is between five to ten years, you may need to get a new one much earlier than the box spring. On the other hand, a box spring can get worn down at the same rate as a mattress, but it can take ten years before needing replacement. 


How Long Should You Keep Your Mattress And Box Spring?

The mattress and the box spring can get worn down at the same rate, but not all mattresses can last as long as a box spring. Therefore, you need to check them separately to know how long you must keep them. For example, a mattress with a life expectancy of five years will need an earlier replacement than a box spring that has been yours for much earlier but can last for ten years. 


When to replace your mattress

The mattress replacement period is not a one-size-fits-all, but a good time to get a new one is after seven to eight years. However, do note that some mattresses can even last for a decade or more, as proven by the warranty period of some brands.

A box spring is also exposed to your usage as the mattress, but it can last as long as ten years. Therefore, it’s unnecessary to get a new box spring for every new bed, but it’s still a reasonable timing. 


Why Should You Replace Your Mattress Every 8 Years?


Poor sleep quality

The most significant reason you must replace your mattress around every eight years is that an old bed can affect your sleep quality. Remember that the original construction of the mattress can get ruined as its materials get worn down as years pass. Even if you do remedies like fixing a sagging mattress or repairing the springs and other components in the bed, it won’t give you the support and comfort ideal for a consistent good night’s sleep and prevent body pain in the morning.  



An unsupportive and uncomfortable mattress can cause you to have inconsistent sleeping patterns or even sleep deprivation. And unfortunately, lack of quality sleep also leads to other health concerns such as depression, high blood pressure, and early signs of aging. Furthermore, a mattress that has been used for eight years or more has a high chance of accumulating allergens such as mold and dust mites that can worsen asthma and allergies. 


How Do I Know If My Mattress And Box Spring Are Worn Out?


Visual signs

You know that your mattress is at its retirement when there are changes in its appearance. For example, the material may look discolored regardless of cleaning, and the surface itself has impressions, dents, or even lumps. Of course, you can try other solutions such as flipping the mattress or using a mattress pad to fix these issues temporarily, but it’s much better to get a new one, especially if it’s more than five years old anyway. 


Poor sleep

The loss of box spring structure will be noticeable throughout the night. You may need to adjust positions more often, you wake up at odd hours, or even take a longer time to fall asleep. If you wake up tired the next day, your bed might not be as relaxing as it used to be. 


Body pain

The lack of support because of the deformed box spring and uneven mattress surface will inevitably cause body pain. In addition, your muscles no longer relax when lying down, and your spine is not in the ideal neutral position. So be on the lookout for discomfort, especially on the lower back, shoulders, and hips. 



And that’s it! In this article, we answered how often should you replace your mattress and box spring and found out that it can be at the same time. However, remember to consider that box springs last longer than mattresses. 

Both the box spring and mattress will be exposed to wear and tear. Therefore, monitor your sleep quality and even health because they can indicate that you need to replace the two. Remember that the box spring is needed for support, while the mattress is responsible for comfort and pressure relief.
