A die-cast aluminium shell made up of many small, perforated and triangular faces. Chair_One is in a certain sense built like a football, i.e. with a series of flat ele- ments joined one to the other at angles to create a three-dimensional shape. All this is achieved by exploiting the potential of die-casting which is a precise technology allowing complex three-dimensional shapes to be obtained from metal (in this case aluminium). The result is therefore a chair in which the spaces prevail over the solid parts to characterise its aesthetic quality. Chair_One has now become a classic of the future.Stool_One: legs in anodised aluminium or painted in polyester powder. Seat in die-cast aluminium treated with sputtered fluorinated titanium and painted in poly- ester powder. Suitable for outdoor use. Also available cushions in fabric (Kvadrat “Steelcut Trio” or “Steelcut 2”) or in leather for indoor use.
