How To Fix A Sagging Mattress (Tips and tricks)

You settle into bed but instead of feeling supported by your mattress, you feel like you’re sinking into it.

Your mattress certainly shouldn’t feel like quicksand, and over time this can lead to aches and pains or problems such as insomnia, which has been linked to health problems such as high blood pressure.

What’s causing your mattress to sag?

There are many possible culprits, but one of the most common is due to how you sleep on the mattress every night. If your body keeps pushing into the mattress at certain spots in it, this can cause it to sag in those areas over time.

However, that’s not the only reason why your mattress feels saggy.

Let’s take a look at other common reasons for slumping mattresses, as well as how to fix a sagging mattress yourself. 

Why Is Your Mattress Starting To Sag?

Besides for sleeping in the same position every night, which could cause your mattress to sag over time, there are other reasons that could be causing your mattress to sag. These include:

  • The materials in the mattress are becoming softer. Mattresses that are made of latex and foam can become softer after a lot of use, as Tuck reports. In addition, if you have a bed with springs this can also cause sagging because the tension in the coils will decrease over time.
  • The mattress is of low quality. If the foam of your mattress is of the low-density variety, for instance, this will weaken much faster over time than a bed that has high-density foam.
  • You and your partner cuddle in the middle of the bed. This can cause sagging to occur in the center of the mattress, and can cause you to feel uncomfortable when you move to the sides of the bed. It might not be you who’s causing those indentations, though. If you have large pets who love to sleep on the bed with you, they could be causing sagging in certain areas.

How Can You Stop Your Mattress From Sagging?

Maybe you haven’t had your mattress for a short amount of time and you don’t want to have to buy a new one.

Luckily, there are ways to counteract mattress sagging. Here are some tips and tricks you can try to breathe new life into your mattress and get a better night’s sleep.

Rotate Your Mattress

You should do this every six months even if your mattress hasn’t started to sag.

Not the same thing as flipping it over, rotating your mattress means that you move it around so that the head of the mattress is at the bottom and the foot of the mattress is now at the top.

This alleviates the mattress’s pressure points and can help it to wear away more evenly instead of causing weak spots in certain areas and not others.

Chances are, rotating your mattress will make you feel like you’re sleeping on a brand new, and much more supportive, one!

Buy A Mattress Topper

As its name suggests, a mattress topper goes on top of your mattress. It’s usually a layer of cushioning that offers support, and you can use it to make your bed feel firmer and more comfortable.

Try to find a mattress topper that’s as thick as possible as this will give you an improved feeling and conceal mattress sagging much more.

Mattress toppers don’t have to cost a lot of money – you can find some for less than $100.

Use Gel Pillows

No, you don’t need these gel pillows to rest your head on but to put underneath your mattress!

This is a quick and easy way to deal with mattress sagging. You must put one pillow under each side of the mattress, making sure that you prop them underneath the indentations that are present.

Then, put the mattress back in place and test it out. You might need to adjust it if you’re not feeling support.

Of course, this might not be a long-term solution, but the hard gel pillows will last longer than regular pillows which become softer and less supportive after a few days, as Mashup Mom reports.

Replace Your Foundation

Your mattress might not be the problem – it could be that your bed’s foundation is to blame for why the mattress is starting to sag.

If you have a box spring foundation, give it a looksee to check if any springs look damaged or broken. If that’s the case, it means it’s not supporting your mattress.

You should replace your foundation and the good news is that this does work out to be cheaper than buying a brand-new mattress.

If you don’t want to buy a new box spring right now, Do It Yourself offers this tip: put a sheet of thick plywood between the box spring and mattress to give the mattress more support.

How Can You Prevent Sagging In The First Place?

It’s important to try to prevent your mattress from sagging.

This makes it easier to deal with than having to try to fix it and make it more supportive when it starts to let you down.

Understand that every mattress will experience natural wear and tear over time, but you can prevent your mattress from sagging by switching up your sleeping habits.

If you sleep alone, try to alternate sleeping on both sides of the bed so you don’t let one part of the bed become shapeless after a few years.

If your mattress allows for flipping, you should flip your mattress around regularly so you prevent one side from becoming saggy.

When Should You Replace Your Mattress?

Sometimes trying to repair a sagging mattress isn’t enough to ward off sagging.

You might have to replace your mattress if the sagging is quite bad.

If you’ve had your mattress for almost 10 years, then it’s really old and probably needs to be replaced anyway, bearing in mind that the average mattress will only last for approximately a decade.

You can measure your mattress sag to find out if you qualify for the mattress to be returned to the manufacturer.

Most manufacturers require the mattress sag to be greater than one inch before they repair or replace it, but you should always check this with your manufacturer as some will replace or repair mattresses that have less sagging.

Here’s how to measure how much your mattress is sagging:

  • Remove all the bedding from the mattress so that you get an accurate reading.
  • Get a long piece of string and place it across the mattress width from one side of the mattress to the other. It should be placed so that it is spread across the deepest part of the sagging area. You should fasten the string to the edges of the mattress with a bit of painter’s tape.
  • Next, place the end of a measuring tape on the area of sagging. It should make contact with the part of the mattress that’s sagging the most. This will show you how deep the mattress is sagging and if you should contact the mattress manufacturer for assistance.

sagging mattress tips and tricks for better sleep

Not necessarily. You can find less expensive mattresses that don’t sag quickly, but you have to ensure that they are of high quality.

Check that the foam in the mattress is high-density and that its coils are thick – low-gauge steel springs are the most durable, as Tuck reports.

What mattress is least likely to sag?

Latex mattresses are highly durable and although they might sag a little bit in their first few years of use, they don’t sag to the same extent as foam mattresses.

The mattress that’s least likely to sag overall is the airbed mattress, due to how it has strong air chamber supports.

Conclusion

Dealing with a saggy mattress is no fun.

It interferes with your sleep quality and can cause you to wake up with aches and pains all over your body. If you’ve got a saggy mattress on your hands, there are ways to make it more supportive, as we’ve outlined in this article.

If it can’t be fixed with a few DIY efforts, you might be able to get it replaced by your manufacturer. Here’s to less sag and more sleep!
