How to Fix a Sagging Mattress: 6 Proven Methods

fixing sagging mattress

Did you know that nearly 35% of all Americans get less than 7 hours of sleep per night? Even worse, more than 1 in 10 US citizens are also diagnosed with sleep apnea, a condition that significantly deteriorates the quality of your sleep

Another thing that can make your sleep worse is a sagging mattress. A mattress starts to sag as a result of various factors. For example, the older the mattress, the more likely it is to become sagged. The sag usually develops in the middle of the mattress or on a place where a lot of pressure is being applied. If you sleep on the left side of the bed, that’s where the sagging develops over time.

Still, the question is – how to fix a saggy mattress?  

Luckily, there are several you can do that. Keep reading to learn how to fix a sagging mattress to potentially make your mattress feel like it’s brand new.

Why Is My Mattress Sagging in the Middle?

There are a number of reasons why your mattress might be sagging.

It could be that your mattress is starting to break down before its time (possibly from direct sunlight). It could be that liquid penetration has compromised the integrity of the mattress. Or the problem could be more structural in nature, having to do with the box spring, bed frame, or the surface that it’s placed on.

But more often than not, a mattress is likely sagging in the middle because it’s simply getting old.

Over time, your sleeping habits cause physical changes in the materials within your mattress. And areas that receive frequent pressure tend to lose their structural integrity faster than other areas.

For instance, the position of side sleepers may lead to dips where their hips typically go. Pets can also cause small, sagging areas of the mattress.

And finally, the weight of our bodies also tends to cause sag in the areas we sleep the most.

Is a Sagging Mattress Bad?

Yes, it can be.

Sagging mattresses don’t provide the kind of support most people need in order to sleep comfortably.

For most, that means less sleep and a lower quality of sleep.

This is especially detrimental because 32.6% of working adults already report sleeping 6 or fewer hours per night—less than the 7 to 9 hours recommended.

It’s no wonder almost half of Americans report feeling sleepy between 3 and 7 days a week.

Plus, poor sleep is connected with a range of health problems, including:

  • Memory problems
  • Mood instability
  • Weakened immunity
  • High blood pressure
  • Mental fog
  • Weight gain
  • Risk of heart disease and diabetes
  • Lower sex drive

Sleep deprivation is clearly a serious problem.

And while a saggy mattress may not seem like that big of a problem, it can make getting a good night’s rest even harder than it already is.

Signs That Your Mattress Is Really Saggy

Apart from the obvious visual clues, a sagging mattress usually shows other “symptoms” of deterioration and damage. Here are some of them:

1. You Feel Like Falling From Your Bed

A sagging mattress doesn’t support your weight properly, so you’ll probably experience a weird sensation of falling from your bed or falling in the center of your bed while sleeping.

This sensation will eventually make you develop “protective mechanisms” such as having a pillow on your back for support or sleeping in an uncomfortable position.

2. You Wake up Tired

A sagging mattress usually deteriorates the quality of your sleep. This happens because you become conscious about the “hole” in the middle of the bed, and you probably try to do anything to avoid it. This constant struggle during the whole night keeps you from having a restorative and peaceful sleep, and that’s why you wake up tired.

3. You Wake up with a Painful Back

Since a sagging mattress doesn’t provide proper support to your spine anymore, you can develop mild back pains in the long run. This happens because your weight is unequally distributed, and excessive pressure is put on some of your nerves and muscles.

As a result, you wake up in the morning with a sore arm or pain in your back. You probably don’t know why this is happening, and you blame the pillow. In fact, your sagging mattress might cause this problem, and that’s why you should fix it soon.

How Do You Fix a Sagging Mattress?

Keep in mind that there are no quick fixes when it comes to fixing your saggy mattress, but you can do something to solve the problem in the long run. Here’s what you have to do:

1. Flip the Mattress Upside Down

This solution is great for double-sided memory foam mattresses.

If you have one of those pads, try to flip it upside down. This will change the position of the sagging area and hopefully fix the problem. The idea is that you’re going to apply pressure on a completely different spot once you have flipped the mattress.

As a result, its shape will eventually even out, and you’ll enjoy a less saggy mattress in the future. It’s hard to predict when your mattress will return to its normal shape, but give it a few days or weeks and see how it goes. If the mattress starts to become saggy again, flip it back up and repeat the process.

2. Rotate the Bed

In some cases, the mattress cannot be removed from the bed, so you cannot flip it upside down.

However, you can still try to fix it. Simply rotate your bed so that you sleep in the opposite area of the mattress. This will cause a counter-pressure which will eventually even out your sagging mattress. Again, give it a couple of days or weeks for your mattress to return to its original shape.

3. Use a Mattress Topper

A premium mattress topper, when used properly, can save the day in this case.

Toppers are usually placed on top of the mattress to protect them over the years as well as making your sleep much more comfortable. They can be made from different materials, and they have custom sizes and thicknesses.

Find a thick topper that matches the size of your bed and place it on top of your mattress. This will eventually even out the indents, sags, or bumps in your mattress and improve the quality of your sleep.

Best of all, a mattress topper can be used on a regular basis to prevent additional sagging. If the topper itself deteriorates, you can simply replace it with a brand new one. Toppers are much more affordable than mattresses, so you can save a lot of money in the long run.

Some homeowners found this solution to be successful when it comes to sagging mattresses.

A small pillow placed between the mattress and the bed frame or box spring changes the pressure levels, making your mattress return to its original shape. Although this won’t happen overnight, it’s a good and simple way to attempt fixing a saggy mattress.

If just one soft and small pillow is not enough for this purpose, use a combination of pillows and blankets. The more support you can add to your mattress, the better.

5. Use a Piece of Plywood

In some cases, you need to add extra support to your mattress to prevent it from sagging.

A piece of plywood can be successfully used to do that. Place this piece between the mattress and the bed frame. The mattress will rest on the plywood and hopefully return to its original position in a couple of days or weeks.

With that being said, keep in mind that your mattress might feel a little harder at first, but hopefully, you’ll get used to it. You can also use a combination of a topper and plywood to “sandwich” your mattress and make it come back to its normal shape.

6. Inspect the Box Spring or Bed Frame

In some cases, the bed frame itself might be damaged and cause the mattress to become sagged.

Make sure that you detach the mattress completely and inspect the frame. Are the wooden pieces damaged? Is something bent or deteriorated that causes the mattress to sink when you sleep on it? If the answer is yes, then you need to fix the bed frame first before fixing the mattress.

If the answer is no, then the mattress itself is the culprit, and you need to follow the aforementioned tips to make it come back to its original shape.

How to Prevent the Mattress from Becoming Saggy

Learning how to fix a sagging mattress is a good idea, but it could be even better to prevent this problem right from the start, right?

Well, luckily, you can do something to prevent your mattress from sagging too soon. Here are a few tips:

1. Inspect Your Mattress Often

At least once every month, make sure that you take a closer look at your mattress and scan for sags or bumps.

It’s better to identify a small indentation and attempt to fix it instead of having to face a more difficult problem with your mattress. Use a ruler or something similar to check how flat your mattress is. If you discover deep angles, you need to fix them before they get worse.

2. Apply Pressure Evenly

In other words, you could try to sleep in different places of the bed from time to time. This prevents the mattress from becoming too accustomed to pressure in just one spot that it cannot recover once the pressure is removed.

Once every two or three months, you can switch places with your partner and sleep in different positions. Also, make sure that your bed frame has proper support in the center since that’s where most sags tend to start.

3. Go for a Metallic Frame

In some cases, this can help you enjoy your mattress for more years as it provides better support.

Wooden bed frames tend to deteriorate quicker with the passing of time. This means that the wood elements become more fragile, and they might crack under years of pressure from your body. As a result, the mattress sinks into the hole created by broken wood pieces, and a hole will develop very quickly.

If you go for a metallic frame for your bed, you can prevent having to deal with a sagging mattress. Metal is much more durable than wood, and it can last for a lifetime, no matter how heavy you are. Metallic frames provide additional support to the mattress and extend its lifespan.

With that being said, keep in mind that a bed mattress should be changed once every 10 years, depending on its quality and materials.

How Do You Fix a Dip in the Middle of a Mattress?

While the 6 tips for how to fix a sagging mattress listed above can all help, the best and most realistic option is a new mattress topper (if you don’t want to replace your current mattress, that is).

A new mattress topper is an inexpensive way of adding the structure and support you need to your current bed without having to invest in an all-new mattress.

Added to that, mattress toppers can also help keep your mattress clean and cool—perfect for those who have a hard time staying at just the right temperature throughout the night.

Best Mattress Topper for Sagging Mattress

The key to getting the most benefit out of using a mattress topper to fix a sagging mattress is cushioning and support.

As a result, you’ll want to look for thick, high-quality mattress toppers to help counteract any deformity in your mattress.

You’ll also want to look for toppers that have multiple layers of material inside. For instance, a combination of premium wool and gel-infused poly foam work together to give your bed plushness without skimping on structural support.

That means you want to use only premium mattress toppers.
