Futons are traditional sleeping and seating furniture that originate from Japan and consist of a thin mattress that can be easily folded or rolled out. They are used as a flexible sleeping solution and can be stored away during the day to save space. In modern applications, the term also often refers to futon sofas, in which a mattress rests on a collapsible frame that can serve as both a sofa and a bed. Futons are known for their minimalist design, versatility and space-saving features, making them popular in compact living spaces.
