Binaria is one product that has been unique for many years. The Binaria was developed by the doctor, Jordi Badia in co-operation with the industrial designer Otto Canalda. It is not simply a stool, it is a seat designed on well researched medical principles. It is highly recommended for any activity where you have to sit down, but at the same time you are required to maintain certain mobility. Especially in the work place. The development of the Binaria has been based on detailed ergonomic and anthropometric studies. For any occupation, be it a dentist or a supermarket cashier. the patented shape of the seat guarantees the healthiest position of the backrest in relation to the legs. This being 135°.The characteristic split in the centre of the seat ensures the legs of the user are positioned in the most natural way, creating both stability and good hip articulation. Binaria is a work seat that feels really good. In actual fact the design is well proven. It was first launched in 2003 for the company Oken which does no longer exist. BD Barcelona Design have now added this product to their range. lt is available in the three original finishes of White, Black, and Red and e new version in leather.
