Ergonomics is their business! Jobri is invested in producing all kinds of ergo products from pillows to massagers to chairs. We carry their superb quality ergonomic kneeling chairs that are built to exacting standards. Kneeling chairs were one of the first ergo chairs, designed with the body's angles in mind. They are successful in alleviating pressure and stress on the lower back, creating an open body angle. Often copied never replicated! Jobri chairs ship in 1-2 days. Try a different way of sitting, your back will thank you.
