The ball chair is a an exciting tool that makes it easy for children to sit up straight, and and engage their cores while seated. This encourages a good, upright posture and activates trunk and abdominal muscles. While children are sitting on a ball, they are allowed some vestibular input through bouncing or rocking. This allows their brain to remain engaged and it is easier to focus on processing new information, exam taking, and other pertinent aspects of classroom learning. Many educators report great success in using these chairs to increase attention and focus in children while seated in the classroom.
