Antonio Citterio has designed a collection that represents the expression of a modern language, with clear references to the Knoll tradition of classic design. Particular emphasis has been placed on sustainability, with the use of natural materials like wood and marble.The seating family Klismos by Knoll offers an original combination of materials and dynamic, slender forms. The seats and backs are in natural cotton cord woven on an oak wood structure. The back can be also in wood. Elegant optional leather cushions can be added to the seat for greater comfort.
