Top 10 Best Sofa Bed Mattress Replacements in 2024 – Complete Guide

Best Sofa Bed Mattress Replacements

You own a stylish sofa bed if you are searching for a sofa bed mattress replacement. A sofa bed is quite unique furniture. It not only offers a comfy space for sitting in the living room, but it can also turn into a bed when there is a demand for an additional bed in your apartment. A good quality sofa bed can provide years of unproblematic service.

Even though you have bought the best couch in your budget, the regular operation can cause wear and tear. You will have to buy a replacement mattress when the old one is not usable. That’s where this guide will help you in making an informed decision.

Things to consider before buying sofa bed mattress replacements

It is always confusing and a bit difficult to choose the right mattress. You get too many options and all of them seem impeccable. However, you need only one to replace the old mattress and that one should be perfect as per your comfort demands. Choosing a perfect mattress will be quite easy for you if you consider the following things.

Which type of mattress do you want?

There are different types of replacement mattress for the sofa bed, which are as follows:

  • Memory foam mattress:

Millions of people are using memory foam mattresses. Memory foam as a material provides great benefits when it comes to enjoying a healthy 8 hours’ sleep. The pressure point reduction capability of memory foam mattresses is simply awesome. It will take shape as per the needs of the sleeper and then get back to its original shape very quickly. You get a comfy surface to sleep every night. In addition, you do not need to flip the mattress after using it from one side for a long time.

  • Foam mattress:

It is another one of the most commonly used materials to produce mattress. It is not as comfortable and as feature-rich as memory foam and latex, but it is a more affordable solution. If you are looking for an affordable replacement mattress for the sofa bed, you can consider a foam mattress. It is actually a great choice if you are not going to use that sofa bed on a regular basis. Foam mattresses can remain comfortable and cozy if not used on a daily basis. That’s why it is a worth considerable choice.

  • Latex mattress:

Latex is an innovative material used to produce mattresses, toppers, and pillows. It should be your first choice if you like to sleep on a firm or medium-firm bed. You can use latex mattress on a daily basis and it will not lose its comfort levels for a very long time. That’s what makes it a pretty special choice. Latex is obtained from rubber trees and soy plants. Therefore, you can say a latex mattress is the most eco-friendly sofa bed replacement mattress.

  • Coil mattress:
Pocket Coils

One of the most widely preferred mattress types is coil mattress. A coil mattress is also the most standard kind of sofa mattress. A simple coil mattress with a thin layer of foam at the top cannot provide optimum comfort. However, when coupled with two or more layers of memory foam, latex, and HD foam base, a pocketed coil mattress can provide the best comfort. You can bank on this type of mattress to get greater comfort along with better pressure release points. A hybrid coil mattress can work really great to prevent back pain and other similar issues. That’s why it is an awesome choice.

The size of the mattress:

The second most important thing you should consider is the size of the mattress. It should not be quite tough for you to do if you already know the size of that old mattress. You can measure the sofa bed frame to assess the best size of the mattress. Do not measure that old mattress because it is not in its original shape now. The dimensions of that mattress are changed over the years and that’s why you should measure the bed frame. Take an accurate measurement of area in the bed frame and compare it with the size of new mattresses. You will easily find a mattress in that size.

The build quality of the mattress:

All the popular mattress manufacturing brands provide mattresses featuring two or more layers. The number of layers determines how comfy and how supportive a mattress will be. Whether you will use that sofa bed occasionally or on a regular basis, make sure the layers are placed perfectly to offer full-body support.

You can find mattresses featuring gel memory foam layer, air-infused memory foam layers, pocketed coil layer, and HD base layer at the bottom. Whatever number of layers there is, the mattress must provide top build quality to provide a comforting sleep throughout the night.


A mattress can help you a lot in coping with back pain and other sleep issues if its firmness level is perfect. Many people do not consider this crucial aspect of the mattress and it costs a lot in the end. You might wonder a soft mattress is always the best to enjoy a restful night, but that is not true. You get three types of firmness levels in mattresses: soft, medium-firm, and firm.

Your chosen mattress must sufficiently conform to the shape of your body but it should also offer great pressure relief points. Therefore, you should reveal what firmness level is the best for your rest and then pick the right mattress for your sofa bed.
