z-ball
z-ball is the ultimate ergonomic inflatable playing- and sitting ball with 3 equal handles.Beside the benefits of existing sitting balls, like creating an open-hip-edge and the dynamic sitting, the z-ball makes an even better position of the S-attitude of the back possible. Many people are sitting wrong on existing sitting balls: they sit in the middle of it and create a bad position of the back. In this z-ball, the logical position of the handles stimulates to sit more at the front of the ball and gives in the mean time support to the loin: the ultimate sitting position results. To fix the ball, you can turn it upwards.
