The bulbous, fluffy design of the Biboni Sectional Sofa from Knoll features a curving shape that accommodates the human form, resulting in a fresh, friendly form that evokes the classic Chesterfield character. Designed by Sharon Johnston and Mark Lee of the architecture firm Johnston Marklee, and made in Italy, its wood frame is softened by foam and sheathed in a blended upholstery that offers both softness and strength. The sofa appears almost to float in the middle of a room, with a textured surface that appears to shift with changes in the light around it.
