First off, to check and see where the mattress is sagging [1], you should put a flat object on the mattress and check the space in between the flat object and the mattress. Usually, places that heavy body parts get placed are the parts of the mattress that become saggy. Sadly, it is very difficult rather than impossible to fix a saggy mattress other than sending it to the manufacturer, but some ways will remove the feeling of a mattress being saggy.

Some of the top-rated memory foam mattresses might last for a very long time. The cheap ones might get saggy real quick, but they also have a very easy solution for fixing sagginess. Because the memory foam mattresses are usually two-sided, to fix the sagging parts, flip the mattress around, and use the other side which is not saggy.

Rotate the Mattress

It is recommended to rotate the mattress every once in a while to protect it and prevent the mattress from becoming saggy. As we mentioned, the parts that get saggy are usually the parts where there is the most amount of pressure from the body on them. For example, the head, shoulders, or hips. It is good to rotate the mattress to let the parts where there are pressures on rest. Your feet do not put much pressure on the mattress, so if the place you lay your head on feels saggy, rotate it, and let your head lay on the area that is comfortable. Your feet will not feel the mattress being saggy as much as your upper body. Although some manufactures might recommend against rotating the mattress, if not, doing it would be helpful.

Use a Topper 

If rotating and flipping do not work is not an answer to how to fix a sagging mattress, and if the sagging of the mattress is slight and unnoticeable, the sagginess can be fixed with a mattress topper. There are different mattress toppers and some might not fix the mattress, so make sure that you get the best mattress toppers for a better experience. Besides the quality, a topper will affect you better if you are light-weighted, and you sleep alone. One thing to keep in mind is that a topper might completely mess up the firmness of the mattress, and they usually make for a very supportive and soft layer, so make sure you choose the topper for your mattress wisely.

Add Extra Pillows

Some people might prefer to have pillows underneath their feet, hips, or any other area of their body. A pillow with a suitable shape can also fill up the sagging area and make the bed more comfortable. However, it will make that feel different, and you need to be careful to do this the right way. You can also place the pillows underneath the mattress to make the sagging areas pop up. 

Check the Foundation of the Bed

Sometimes, the problem of a sagging mattress can be from the foundation of the bed. Some beds have a weak foundation. Usually, the ones that have less than six legs to support them around the center of the mattress tend to be the weaker options. The bed foundation might also be old and worn out. The sagging in this situation usually is caused by the slats. To fix this, try having a better bed foundation for the bed. The best option is to take the mattress's recommendation on what type of bed you should be taking that supports the mattress in the best way. It is also possible to support the foundation with more materials such as plank woods or plywood to reinforce the bed frame. Make sure the materials you are using are strong enough and will not break.
