The Rayuela Stool is made from recycled wood by Spanish designer Alvaro Catalán de Ocón. The most efficient form, offering the greatest possibilities, is the rhombus. Three of them make a Hexagon, which is the best way to cover a surface. The Rayuela Stool uses three different finishes to create a fascinating optical effect. The stool was recently exhibited at Spazio Rosanna Orlandi, Milano.
