Large decorative chests known as cassoni remained the most popular type of furniture in use in the homes of the Italian urban elite during the 14th through the 16th centuries. They were one of the trophy furnishings of rich merchants and aristocrats and cassoni would be recognizable in most Italian homes of this period. The basic form was extremely simple consisting of a roughly rectangular chest that served a variety of different functions. They stored and protected clothing, linens and other valuables and they could also be used as seats. Cassoni, however, varied greatly in terms of shape, size and decoration. Some versions were equipped with a lock for security and were known as forzieri.
