How to Fix Mattress Indentation

If you’ve ever experienced a mattress indentation, you know how frustrating it can be. Waking up with a sore back or feeling like you are sinking into a crater can disrupt your sleep and leave you tired and unrested. But fear not!

This comprehensive guide will delve into the depths of mattress indentation and provide practical solutions to fix mattress sag. Whether you have memory foam, innerspring, or hybrid mattresses, we’ve got you covered.

How to Fix Mattress Indentation- Step-by-Step Guide

Bed indentation can occur due to various factors such as age, improper support, or low-quality materials. Regardless of the cause, here are some practical ways to fix indentation in your mattress and regain your sleeping oasis:

1. Rotate and Flip Your Mattress Regularly

One of the simplest ways to prevent and fix mattress indentation is to rotate and flip it regularly. Most mattresses are designed to be reversible, allowing you to sleep on both sides.

By flipping your mattress, you distribute the weight evenly, preventing excessive wear and tear on one side. Additionally, rotating your mattress every few months ensures that body impressions don’t become permanent, extending its lifespan.

2. Use a Mattress Topper

Opt for a high-quality memory foam or latex topper, as they contour to your body and distribute the weight evenly. Not only will a mattress topper improve your comfort, but it will also extend the life of your mattress.

3. Add Extra Support with Plywood

Adding plywood between the mattress and the bed frame can work wonders for mattresses that lack proper support. Measure the dimensions of your mattress and cut a piece of plywood to fit snugly between the two.

This additional support prevents the mattress from sagging and helps eliminate existing indentations. Ensure the plywood is smooth and free of sharp edges that could damage the bed.

4. Utilize Pillows for Targeted Support

If you’re dealing with a localized mattress indentation, strategically placing pillows can help provide targeted support. For instance, if there’s a dip in the middle of your mattress, try putting a firm pillow underneath to level it out.

Experiment with different pillow placements until you find a configuration that provides comfort and support.

5. Vacuum and Clean Your Mattress

Over time, dust, debris, and sweat can accumulate within your mattress, exacerbating the indentation problem. Regularly vacuuming your bed can help remove these particles and keep it clean.

Additionally, consider using a mattress cleaner or a mixture of baking soda and essential oils to freshen up your mattress and eliminate any odors. A clean bed not only promotes better sleep but can also minimize the appearance of indentations.

6. Seek Professional Help

If all else fails and your mattress indentation persists, it might be time to consult a professional. Reach out to the manufacturer or a trusted mattress expert to assess the condition of your mattress.

They can offer personalized advice and recommendations based on your specific situation. Sometimes, they suggest repairing or replacing the mattress to restore optimal comfort.


Don’t let mattress indentation rob you of a good night’s sleep any longer. By following the techniques mentioned in this guide, you can restore the comfort and support of your mattress.

Remember to rotate and flip your mattress regularly, consider using a mattress topper, add extra support with plywood, strategically place pillows for targeted support, and keep your bed clean.

If the problem persists, don’t hesitate to seek professional advice. With these solutions, you’ll be well on your way to fixing mattress indentation and enjoying restful nights again.
