How To Fix A Sagging Mattress


How Do You Fix A Sagging Mattress?


Rotate it

Perhaps the most obvious way to fix a sagging mattress is to rotate it. Not only is this a quick fix, but it can also be a preventative measure for sagging itself. Depending on the material your mattress uses, it might benefit from rotation regularly. 

If you think about it, a mattress sags because of the consistent pressure in that area. Rotating the mattress will help distribute the pressure, so the sagging focuses not only on one place. Make it a habit to check where your hips and shoulders lie and rotate your mattress to help the other parts receive pressure too. 

How do you rotate a mattress per se? The body areas mentioned will go to the other parts of the mattress by swapping the latter’s head and foot. You can do this every three to six months, as long as the manufacturer doesn’t say it’s not allowed or you’re using a one-sided mattress that can’t be flipped. 


Use a mattress topper 

Some mattresses are one-sided, and rotating them is not a viable solution. The material your mattress uses might not also benefit from flipping. If these are your issues, consider using a mattress topper instead. 

You’ll put it on top of the bed as an additional layer where you’ll lie. This way, you can prevent further sagging or fix a sagging mattress that is no longer supportive because of the dents. After all, a considerable gap between the bed and the body is not ideal for posture. 

Much like mattresses, toppers come in different materials and thicknesses. You must select the right density for you and how saggy your mattress has gotten. While using a mattress topper will not restore a sagging mattress, it’s a viable solution for those who can’t get a mattress replacement yet. 


Check your bed foundation

The final solution you can do for a sagging mattress is to replace your bed foundation. This is because it can worsen sagging or even cause sagging itself. The foundation should never be fewer than six legs because it won’t be supportive enough, especially in the area where the mattress receives pressure. 

You also want to check if the foundation is suitable for your mattress. Manufacturers should offer information on what foundation style is best for their mattresses. For example, what’s the ideal distance between the slats?

A quick tip to remember is to avoid box springs for foam and hybrid mattresses. Platform and foundation are more ideal for these mattresses. By getting the best foundation for your mattress, it will stay supported and prevent further sagging. 


Why Is My Mattress Sagging In The Middle?

To further understand how you can fix or avoid a sagging mattress, you need to know the reason why it happens. The sagging is commonly in the middle part, which is even more frustrating because you’ll lose support when you lie down. This area sags because of this very reason; it’s exposed to the daily wear-and-tear. 

The mattress will lose its structure over time because of the consistent pressure every night. You’ll notice that you are sinking, or you might even wake up with body pain. Sagging is typical regardless of the mattress material because even the metal coils in innerspring mattresses experience them. 

The comfort layer will lose its firmness, and the metal coils lose their tension. Always check where your shoulders and hips are in the mattress and flip the area now and then to distribute the pressure. Now, is sagging mattress terrible or just a pet peeve we should get over with?


Is Sagging Mattress Bad?

A sagging mattress is bad because it affects our comfort and even sleep quality. More so, you’re losing the proper support to maintain spinal alignment. You’ll wake up with body pain and stiff muscles, which are enough reasons for you to remember the three methods we discussed earlier. 



If you wake up every day with back or neck pain, your mattress might be the one to blame. Besides restoring a lumpy pillow, you must know how to fix a sagging mattress to maintain the ideal sleeping posture. Practice flipping your bed every three months or add a mattress topper to return the support you lost. 

You can also check your bed foundation if it successfully supports your mattress to prevent sagging. By doing these three practices, you can prevent premature sagging or even avoid worsening the issue. However, consider getting a new mattress after it has surpassed its expected lifespan. 

Remember that it should be part of your maintenance to replace your mattress after a couple of years. You can also check the warranty if it still covers your mattress. Regardless, never overlook the support you should get from your bed to avoid discomfort and body pain in the long run.
