It is one of the most singular pieces of recent years. It is the work of a doctor, Jordi Badía, and industrial designer Otto Canalda. It is not simply a stool, this is a seat with medical prescription. It is specially recommended for all those activities which are undertaken in a seated position but require mobility. There are many of these in the working ambit: from the dentist to the supermarket cashier. The shapes of the seat, which are patented, guarantee the most beneficial position for the back with respect to the legs. At exactly 135º. The shapes have been developed from a meticulous anthropometric study and are characterised by a central division, which makes it natural to separate the legs and so achieve stability for the coxofemoral joint. Binaria is a chair which feels good. It has had time to demonstrate this fact. It first appeared in 2003 in the catalogue of the Oken company, which no longer exists. BD Barcelona Design now includes the chair in its own catalogue with three classic finishes – black, white and red – and a new version in leather.
