The Bio Office Chair is a simple swivel chair supported on five castors with a height-adjustable seat. The castors form part of an elliptical tubular steel structure that perfectly integrates with a polypropylene or upholstered seat and back rest. The cold laminate steel structure is available lacquered with back supports and optional arms in injected aluminium. With optional chrome wheels, the ergonomics and functionality of the Bio Office Chair make it ideal for professional environments such as offices and work spaces.
