The ONGO Seat
ONGO is a young German company, whose main product is a stool that they are promoting as both furniture and exercise equipment.
The ONGO Seat has a curved footprint and a built-in ball track at the base, which follows every movement of the seated occupant. The movement of the seat is transferred directly to the ball. Each position change creates an acoustic feedback through the rolling noise, which encourages movement to prevent tension, strengthen back muscles and improve posture.
