5 Best Sofa Bed Mattresses (Review) In 2021Last Updated: January 15, 2021
If it's time to replace your sofa bed mattress, you've probably realized that you can't just use a regular mattress, which is far too thick for the job and won't fold up into the frame. Instead, you need a replacement mattress specifically designed for sofa beds, that will be thin enough to fit comfortably into the frame but thick enough to provide support and make sure that you or your overnight guests sleep comfortably. Some people even opt to treat themselves to a replacement sofa bed mattress almost as soon as they buy their sofa bed because the mattresses that come with them tend to be somewhat thin, or made with innerspring that can be notoriously uncomfortable (and sometimes noisy)! This guide is designed to help you find the best sofa bed mattress for your needs, with reviews of some of the most comfortable memory foam mattresses on the market. We look at why memory foam sofa bed mattresses make such a good choice and how they are constructed in layers to provide cushioning and support. We also have some advice about just what to look for when making your decision, with tips for choosing the right level of firmness, the correct dimensions, and compatibility with the different types of frames you'll find on sofa beds. We even share some tips on the best ways to clean off pesky stains and keep your sofa bed mattress smelling fresh for as long as possible!

Classic Brands Memory Foam Replacement Mattress Sofa Bed - Best Value
This 4.5-inch memory foam replacement mattress for a sleeper sofa bed is designed to keep your guests totally comfortable throughout the night. Memory foam has a great ability to return to its original shape after being compressed, which makes it one of the best mattress materials around.

The feel of this mattress is 'cushion firm', which is the perfect blend of comfort and support, and ideal for all users.

This means that it is deliberately constructed with breathable foam that uses a porous, open-cell design to allow the air to freely circulate. The result is the best possible night's sleep for you or your guests as it avoids the uncomfortable overheating that other types of mattress can sometimes cause. The low profile design makes this mattress useful outside the bedroom, too, and it is perfect for use on boats or in campers.
