Does a sofa bed come with a mattress? 

Ever wondered if sofa beds come with a mattress? If you have, well you’ve come to the right place. Some sofa beds do come with mattresses but not all.  

Sofa beds are like futons, and they are designed to lay out flat to form the shape of a bed, but they don’t come with a mattress. However, a sofa sleeper has a hidden compartment for a mattress within its sofa frame which can be unfolded for easy use and storage too. 

Many sofa beds either come with the mattress included within their frame or you can use the back and seating area of the sofa as a mattress. Although, if you prefer to buy a sofa bed mattress separate then you can check out on the product page, the dimensions of the sofa bed to understand the size of the mattress, that is needed for the sofa bed.
