What is a "sofa bed"?

A sofa bed is a piece of furniture that functions as both a sofa and a bed. During the day, it serves as a comfortable seating area for lounging or socializing. At night, it can be transformed into a bed by folding out or unfolding parts of the sofa.

They come in various sizes and styles, offering both convenience and versatility in a single piece of furniture.
