Why Does My Mattress Have Dents in It?

One of the most common reasons why mattresses have dents in them is poor support. A mattress that lacks adequate support will sag after time, creating a dent or indentation. Poor support can be caused by an old, worn-out foundation or frame, an inadequate bed base, or a lack of center support.

Overweight people also put more pressure on the mattress which can lead to premature sagging and indentations. Additionally, foam mattresses are prone to body impressions because they compress under pressure and don’t fully return to their original shape without proper care.

To prevent this from happening, rotate your mattress every three months and use a rotating schedule for sleeping positions so you’re not always sleeping in the same spot night after night.

This will help to evenly distribute your weight across the surface of the mattress, preventing dents or indentations from forming.

Finally, make sure your foundation or frame is strong and supportive enough for your mattress to rest on. The combination of a good mattress and proper support should prevent any sagging or indentations from occurring in the future.

If you’ve already noticed an indentation in your mattress, there are several solutions that can help fix it.

For example, some mattresses come with “toppers,” which can be added to the top of your bed and help fill in any existing indents, providing extra cushioning and comfort as well as returning the original shape of the mattress.

10 Methods How to Fix Mattress Indentation

Method 1: Rotating and Flipping the Mattress

One of the simplest and most effective methods to fix mattress indentation is by rotating and flipping it regularly. By doing so, you distribute the weight evenly across different areas of the mattress, preventing excessive wear and reducing the chances of indentation.

Method 2: Using a Mattress Topper

Adding a mattress topper can help alleviate mattress indentation. Opt for a high-quality memory foam or latex topper that provides additional support and cushioning to the affected areas.

The topper helps distribute body weight evenly, reducing the pressure on the indented spots and restoring the mattress’s original shape.

Additionally, mattress toppers are a great way to add extra comfort and support for an improved sleep experience. Make sure to purchase a topper that is the same size as your mattress for a seamless fit.

Method 3: Placing Plywood Underneath the Mattress

If your mattress is sagging or has noticeable indentations, placing a sturdy and supportive plywood board underneath it can provide extra reinforcement. Ensure the plywood is cut to fit the size of your mattress and placed evenly across the entire surface to provide consistent support.

Make sure the plywood is thick enough to provide sufficient support and that it isn’t too thick, otherwise it may cause discomfort.

Method 4: Utilizing Mattress Wedges or Bolsters

Mattress wedges or bolsters are specifically designed to target sagging or indented areas of a mattress.

These supportive accessories can be placed underneath the mattress in the affected spots to lift and level the surface, helping to reduce the indentation over time.

They provide support to the area, allowing it to return to its original shape. Mattress wedges or bolsters are a convenient way to fix mattress indentations without having to buy a new mattress. They are easy to install and generally cost significantly less than buying a new bed.

Method 5: Trying a Mattress Refluffing Technique

For mattresses with fiber or down fillings, refluffing can help restore their original shape and minimize indentation. Gently beat or pat the affected areas to redistribute the filling material and restore loft. Repeat this process periodically to maintain the mattress’s shape.

Method 6: Applying Heat to the Indented Areas

In some cases, applying heat to the indented areas can help expand the foam or padding, reducing the visibility of the indentation.

Use a hairdryer or a heating pad on a low setting, being cautious not to overheat or damage the mattress. Apply the heat evenly over the indentation, and then allow the mattress to cool and regain its shape.

Method 7: Using a Mattress Repair Kit

If your mattress has a removable cover or has been punctured, using a mattress repair kit can help fix minor indentations. These kits typically include adhesive patches or foam fillers that can be applied to the affected areas, providing support and filling in the indentation.

Be sure to follow the instructions carefully when using these kits, as they can be tricky to work with and won’t fix deep indentations.

Method 8: Seeking Professional Mattress Reconditioning Services

In cases of severe or persistent mattress indentation, professional mattress reconditioning services can be sought. These services involve specialized techniques such as steam cleaning, foam replacement, or even adding additional layers of support to restore the mattress’s shape and firmness.

Method 9: Investing in a New Mattress

If your mattress is old, worn out, and the indentations are beyond repair, it may be time to invest in a new mattress.

While this may seem like a significant expense, a high-quality mattress can provide better support, comfort, and durability, ensuring a good night’s sleep for years to come.

Method 10: Proper Mattress Care and Maintenance

Prevention is key to avoiding mattress indentation. By practicing proper mattress care and maintenance, such as using a mattress protector, regularly cleaning and vacuuming the mattress, and avoiding placing heavy objects on it, you can prolong its lifespan and reduce the chances of indentation.

Things to Consider When Fixing Mattress Indentation

1. Determine the Cause:

It is important to determine the cause of the mattress indentation before looking into solutions, as this will help narrow down the best solutions and prevent it from happening again.

Common causes of mattress indentation include heavy objects placed on the bed, people sleeping in one spot for long periods of time, or age-related wear and tear.

2. Replace the Mattress:

If your mattress is old and worn out, you may want to consider replacing it altogether as this can help reduce future indentations.

Additionally, if your mattress has specific warranty requirements related to indentations, you should look into them before making a decision.

3. Flip or Rotate the Mattress:

If your mattress is still relatively new and free of major damage or defects, flipping or rotating it every few months can help distribute weight more evenly across its surface and prevent indentations from forming.

4. Add Support:

If your mattress lacks adequate support, you can try adding a memory foam topper or adjustable bed frame to help better distribute weight across its surface. This may be especially beneficial if you find yourself sleeping in one spot for long periods of time.

5. Increase Airflow:

Poor air circulation can cause mattresses to sag over time due to moisture buildup underneath the fabric layer.

Poor Air Circulation Can Cause Mattresses to Sag Over Time

To increase airflow, consider investing in a mattress protector or using a fan to circulate air around the bed while you sleep. This will also help reduce allergens such as dust mites that could potentially cause indentation over time as well.

6. Vacuum regularly:

Vacuuming the mattress regularly can help reduce allergens that could potentially cause indentation over time. Pay special attention to crevices and seams where dust and dirt tend to accumulate. Additionally, you should use a damp cloth to spot clean any visible stains or spots on the surface of the mattress.

By following these tips on how to fix mattress indentation, you can help keep your mattress in top condition and reduce the risk of future indentations.

With regular maintenance and care, your mattress will last longer and provide a more comfortable sleeping surface for years to come.


In conclusion, mattress indentation can be a difficult problem to solve and one you may not have considered until it has caused disruption to your good night’s sleep.

But do not fret, as there are a few ways to ensure that your mattress indentations won’t cause any further sleepless nights in the future. Regularly rotating or flipping your mattress is the most effective and easy way to prevent such indentations, as well as ensure appropriate weight distribution.

Finally, if after trying the above solutions you still find yourself stuck with mattress indentations, consider purchasing a new mattress.
