You can add two pieces of plywood in between the box spring and the mattress. This method is less costly than obtaining a new mattress to sag again in a couple of weeks.

Slats Replacement

You might want to check the slats on the frame underneath the box springs. In case the slats have warped, you might need to replace them with a new one. Adding one or two more slats will provide extra support to the mattress, especially in areas where there are sags.

Here are some of the ideal ways to economically repair your old mattress that is not only effective, but it is also cheaper than having professionals repair your mattress.

Mattress Helper

Mattress Helper is a long foam that you can add to the mattress as filler for the sagging area. Mattress Helper is like a long pillow under the mattress but of a longer and more consistent shape. It is a good investment instead of buying a new mattress that might have cost much only to sag in a matter of weeks, which is not ideal at all.


The bladder is an inflatable pouch that pumps up air into the mattress that can be placed strategically between the box spring and the mattress where the sag is located. A bladder comes in different kinds and sizes depending on the bed that it will be used on.

Foam Topper

A foam topper is a type of mattress filler that will help fill the sag of your mattress. Most of you will think that it is too thin for it to fill the mattress’s sag. But as the saying goes, don’t judge the book by its cover; thus, try using it first before you give your verdict of its usefulness against mattress sags.

Overfilled Plush Mattress Pad

The overfilled plush mattress pad is likely a very fluffy comforter you often used at home; the difference is that it is used to add life to the mattress’s sag. It fills the curves that the mattress is having. It also adds volume to the mattress, making it look like there is no sag visible on the surface.

As doctors say to their patients prevention is better than cure, this saying does not only apply to avoiding diseases but it can also be applied to many things in general. To prevent sags in your mattress, you can shift the mattress in a cycle of three regularly. First, you can change the mattress position by swapping the head and foot area of the mattress; you don’t necessarily need to flip the mattress in doing this. The second is to flip the mattress by changing the top and bottom portion of the mattress effectively interchanging it all together, and lastly, changing the head and foot of the mattress again.

Regular checking of the mattress also helps in preventing sags from showing into the mattress. Checking the box spring of the mattress and the slats help in keeping the mattress in good shape. The spring must be in good condition to avoid sagging the mattress, and slats should not show any sign of warping. Having a good foundation for the mattress helps in preventing sagging from occurring in the mattress.
