Replacement Sofa Bed Mattresses For Every Budget
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 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 a sofa 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 ways to clean off pesky stains and keep your mattress smelling fresh for as long as possible!

Zinus Memory Foam Sleeper Sofa Mattress – Top Choice
The Zinus Memory Foam Sleeper Sofa Mattress is designed to mold perfectly to the contours of your body, this memory foam mattress provides you with the perfect amount of support in all the right places. The foam itself is split into two different layers. The top layer consists of an inch of gel memory foam, beneath which lie a further 4 inches of high-density support foam. This is all wrapped up within a cover made from knitted jacquard, which has a lovely soft feel to it. The BioFoam used in the construction of this mattress has a number of qualities that make it an excellent choice. It contains natural plant oil, which replaces some of the petroleum traditionally found in a memory foam mattress. You can also be confident that this mattress will remain beautifully fresh, as it uses both green tea extract and natural activated charcoal to eliminate odors. Active charcoal is also great for absorbing moisture, helping maintain freshness, and ensuring a cool and comfortable night’s sleep.

Classic Brands Memory Foam – Greatest 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 top mattress materials around. Despite being firm enough to offer orthopedic support, it can easily be folded into most standard sleep sofa beds. Another great advantage with a memory foam mattress is that it is antimicrobial, resisting both mold and bacteria. The Classic Brands Memory Foam Replacement Mattress Sofa Bed is also hypoallergenic. The feel of this mattress is ‘cushion firm’, which is the perfect blend of comfort and support, and ideal for all users. The cover is made from a breathable ribbon knit which feels soft to the touch and the entire foam mattress is ‘self-ventilating’. 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 greatest 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. This replacement mattress is available in twin (with dimensions of 33 x 72 x 4 inches), full (with dimensions of 53 x 72 x 4.5 inches) and queen (with dimensions of 58 x 72 x 4.5 inches).
