Frame in lacquered metal, guaranteed for 10 years. Polyurethane foam padding in different densities, upholstered with a two-layer protective fabric. Loose cushions in polyurethane and dacron; mother-of-pearl buttons. Feet in solid ash in a walnut stain; neutral thermoplastic non-slip glides. Upholstered in fabric or leather. For this project, natural colours and materials such as cotton, linen, hemp, and wool have been used. Fully removable covers. With use the seating will become softer and more "lived-in"; therefore a slight wrinkling of the covering is perfectly normal.
