Our black ball tray provides a firm hold for fitness balls, with a size of 55-75 cm. The plastic tray is the ideal ball stopper, which 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 safe manner. The anti-rollaway effect also makes the ring perfect for sitting on. Simply place the exercise ball of the desired size in the tray and the healthy seating alternative is ready.
