Saggy Mattress

A sagging mattress isn’t only uncomfortable, it can also lead to poor quality sleep and a host of other problems.

  • Your body sinks into the middle or edges of the mattress when you lay down.
  • You feel bumps or ridges in the mattress when lying on it.
  • The mattress has visible dips or indentations in various areas.
  • You wake up with aches and pains, even though you were comfortable before falling asleep.
  • The edge of the bed feels like it’s about to give way when sitting on it for long periods of time.

If you’re experiencing any of these issues, then it’s likely that your mattress is sagging and needs to be fixed as soon as possible!

What Causes a Mattress to Sag?

Defect or Damage

If you’re already dealing with a sagging mattress due to defects or damage, it may be time to take action. In many cases, your mattress may qualify for repair or replacement under its warranty policy. Make sure to contact the manufacturer and inquire about the specifics of their warranty policy; they may be able to provide you with a free repair or replacement if the defect is eligible.

Normal Wear and Tear

Normal wear and tear are the inevitable result of sleeping on a mattress every night. Over time, the materials that make up your mattress start to break down and sag. While this isn’t necessarily a cause for alarm, it can lead to uncomfortable sleep and put extra strain on your body.

Improper Support or Use

Are you experiencing premature sagging in your mattress? If so, improper support or use could be the culprit. It’s important to provide your mattress with adequate support—which typically includes a box spring, platform bed frame, or bunkie board—to ensure it remains stable and comfortable over time.

If you’re using an older foundation that may not be strong enough to support your mattress, consider investing in an updated model with more stability.

How to Fix a Sagging Mattress

Now that you know the signs and cause that your mattress gets to sagging. Here are some important tips you can take action easily.

Use a Mattress Topper

A mattress topper is a great way to improve the comfort and support of your existing mattress. Whether you have an older mattress that’s starting to sag or just want an extra layer of cushioning, a mattress topper can make a world of difference.

Mattress toppers come in all shapes, sizes, and materials, so you’re sure to find one that fits your needs. Choose from 2-5 inches of foam, latex, wool, down alternative or feather for ultimate comfort and support.

With a good quality mattress topper, you can reduce the effects of sagging and even out any lumps or bumps on your bed. Not only will it give you a better night’s sleep but also extend the life of your current mattress! 

Rotate the Mattress

Rotating your mattress regularly is one of the best things you can do to prevent sagging and extend its lifespan. While it’s a good idea to rotate your mattress every three to six months, doing so more often can also be beneficial if your bed is already sagging.

When rotating a mattress, it’s important to swap the head and foot of the bed. Doing this helps redistribute weight evenly so that no one section of the bed gets too much pressure. Additionally, don’t forget to flip the mattress over while rotating—this will help ensure both sides get even wear and tear.

If you’re looking for an easy way to fix a sagging mattress, try rotating it first! Not only will this help improve comfort but also extend the life of your bed significantly! So make sure you add regular rotation into your maintenance routine today and enjoy improved support while saving money in the long run!

Replace the Mattress Foundation

Your mattress foundation can become worn down due to years of use, especially if it’s not made from sturdy materials such as wood or metal. When this happens, the support structure of your bed will start to weaken and cause it to sag in certain areas. Fortunately, replacing the foundation is a simple and inexpensive solution that should help restore your bed’s original shape and provide better support throughout the night. 

Use Extra Pillows

Extra pillows can help to provide support in areas where the mattress is sagging most. It’s important to use good quality pillows with good shape retention that won’t flatten out over time. Pillows made from memory foam are especially effective at providing targeted support.

If you’re looking for an affordable and easy way to fix a sagging mattress, consider using extra pillows underneath your hips, back or legs! Not only will this help to improve your comfort, but it can also help to reduce pressure points that can cause pain and sleepless nights.

Use a Piece of Plywood

Plywood is a great DIY fix for mattresses because it provides the necessary support while still being lightweight and easy to work with. To do this, simply place the piece of plywood between the mattress and the bed frame.

This will give your mattress an even surface to rest on that won’t shift or move around like pillows can. Plus, it won’t take up much space in your bedroom either! With this fix, you should be able to enjoy a good night’s sleep without worrying about sinking into your mattress ever again.

Vacuum Your Mattress to Redistribute Filling

Vacuuming your mattress will help redistribute the filling, making it fuller and firmer. It’s an easy fix that can make all the difference in terms of comfort and support. Plus, it’s a fast and inexpensive way to give your bedding a much-needed boost.

All you need is a vacuum cleaner with an upholstery attachment, such as an extension tube or curved nozzle. Simply run the vacuum over your mattress for about 10 minutes, making sure to cover all areas evenly. This will help disperse any clumps of filler material so that it’s evenly distributed throughout the entire mattress – giving you a more comfortable and supportive sleep surface!

Buy a new mattress

A quality mattress can make all the difference in terms of comfort and support, so it’s essential that you get one that suits your individual needs. From memory foam mattresses to pocket sprung options, there are plenty of choices on the market – each offering its own unique benefits.

When it comes to finding the perfect mattress for you, make sure you take into account factors such as body weight, sleep position preferences, and temperature regulation needs. It’s also important to read reviews before making a purchase – this will help you determine which model is best suited for your specific needs.

With the right mattress in place, you can rest assured that your sleeping experience will be comfortable and supportive night after night!

How to Prevent the Mattress from Becoming Saggy

Preventing a mattress from becoming saggy is much easier than fixing one. With the right habits and attention, you can ensure your mattress remains supportive and comfortable for years to come. Here are a few tips on how to keep your mattress in top shape:

Inspect Your Mattress Often

Inspecting your mattress regularly is essential for keeping it in good shape and avoiding any sagging or lumpiness. Doing so can help you identify any issues early on and take immediate action to fix them before they become worse.

All you need is a ruler or something similar to check the flatness of the surface, and you should be able to spot any indentations or bumps. A few minutes of your time every month will go a long way in ensuring your mattress remains supportive, comfortable, and free from sagging. Better yet, set a reminder in your phone to make sure you don’t forget!

Apply Pressure Evenly

Sagging occurs when the mattress is not evenly supported. To prevent this, it’s important to apply pressure to the surface of your mattress as evenly as possible. Make sure that you and your partner are both sleeping in the middle section of the bed rather than at one end or side.

When lying down, ensure that your weight is distributed across the entire mattress — no one area should be taking more pressure than another. You can also try switching positions occasionally and sleeping on different parts of the bed (as long as they’re supported by a box spring or frame) in order to make sure that all areas are getting equal attention. Doing this will help keep your mattress from sagging unevenly over time.

Go for a Metallic Frame

When it comes to choosing the right bed frame, your best bet is going for a metallic frame. Metal frames are known for their durability and resistance against wear and tear, which means that they can last for many years, no matter how heavy you are.

Wooden frames tend to deteriorate quicker over time, so if you want your mattress to last longer and prevent it from sagging, metal is definitely the way to go.

Additionally, metal beds come in many different styles and designs so you can find one that complements your bedroom’s decor perfectly!

Clean it regularly

Dust mites and other allergens can accumulate in mattresses over time, causing them to become saggy prematurely so make sure you clean yours at least once every 6 months using an appropriate vacuum cleaner or steam cleaner attachment for best results.


Can you fix a mattress that sinks in the middle?

Yes, it is possible to fix a mattress that sinks in the middle. First, determine the cause of the sagging. If it is due to lack of support, consider adding a sturdy foundation or box spring. If the mattress is old and worn out, it may need to be replaced.

If the mattress is relatively new, you may be able to rotate it regularly to distribute the weight evenly or add a mattress topper for extra support. Another option is to invest in a firm lumbar support pillow, which is designed to support the lower back and prevent sagging.

How long should a mattress last before sagging?

The lifespan of a mattress can vary depending on the materials used and the amount of use it receives. Generally, a good quality mattress should last between 7 and 10 years before it begins to sag. However, it is important to note that factors such as the weight of the sleeper, the quality of the mattress, and how often it is used can all impact the life of a mattress.

Regular maintenance, such as flipping and rotating the mattress, can also help to extend its lifespan. Nonetheless, If your mattress is causing discomfort, sagging or is more than 10 years old, it may be time to consider purchasing a new one.

Is a sagging mattress bad for your back?

Yes, a sagging mattress can be bad for your back. When a mattress sags, it loses its support and cushioning, leading to improper spinal alignment during sleep. This can cause muscle strain, tension, and even spinal misalignment. Over time, it can also exacerbate pre-existing back pain and lead to long-term issues. It is important to regularly check the condition of the mattress and replace it as needed to ensure proper support for your back and overall health.


A sagging mattress can be a significant problem, but it is not a lost cause. With the right tools and techniques, you can easily fix and prevent sagging in your mattress.

By following the tips outlined in this post, you can enjoy a comfortable and restful night’s sleep without the discomfort and pain caused by a sagging mattress.
