Furniture Design Please Have a Seat Chair by Ari Korolainen Have a seat is a real ecologically friendly chair. The back of the chair and the seat is made of recycled cardboard. The surface material is recycled leather, which is made of waste pieces collected from shoe and bag factories and pressed to leather sheets. It is possible to make different colour combinations. The frame of the chair is made of wood. One chair requires 5 meters of wooden frame, 5 kg recycled cardboard and 0,5 kg of recycled leather. The chair is like a piece of art, where every wooden part and measurement are results of careful thinking.
