Couches and armchairs similar to this one, characterized the interiors of middle-class homes from the beginning of the 20th century to the end of the 1920s. In his activity as interior decorator, a relatively new profession and quite distinct from that of architect, Frank himself did not claim the authorship of the furniture he was using in his work, although he used it freely, reworking proportions, inclinations and other construction details. The fact remains that through his works he was able to exert an incisive influence on the taste of the period, and that his reinterpretation of pre-existing objects characterized them to the extent of making them seem his own. Not being destined to mass-production, Frank?s designs are known through the photographs of the interiors he decorated. The sofas are simply a two and three-seat derivation of the armchair.
