A. Anti-Breakage and Slow Deflation - Our exercise balls are made of honeycomb structure, which allows them to slowly release air and resist impact when punctured, thus reducing the risk of injury in the event of a fall and protecting you as your lovely mom! B. Non-slip surface - Whether you are at home, at the gym or outdoors, the non-slip surface makes you feel worry-free during exercise. Pilates, yoga, prenatal gymnastics or other low-intensity exercises, as you know. C. Office ball chair for more fun and better posture - Tired of ordinary office chairs? Don't worry! We are at your service! Try our office ball chairs and enjoy a healthier, more active lifestyle. This chair is a wizard that corrects your posture and finally eliminates back pain! Plus, you can even treat yourself to a productive back and abdominal strengthening or some long-deserved deep stretching during or after work! D. Wood or paint are not friendly to exercise balls. So keep the ball away from woodwork, wooden furniture or painted walls. No matter how cute they are, your lovely pets can damage the ball with their sharp claws, so just a reminder to stay away from them when exercising with the ball.
