Our black ball tray offers fitness balls, with a size of 55-75 cm, a firm hold. The plastic shell is the ideal ball stopper that is simply placed on the floor.
The seat shell prevents the ball from rolling away, allowing fitness exercises to be performed in a more controlled and safer way. The anti-roll effect also makes the ring perfect for sitting on. Simply place the exercise ball of the desired size in the shell and the healthy seating alternative is ready.
