Year 0 school girl.
She has a hard time concentrating and sitting still in her chair. She stands on her knees on the chair, lays across the table and turns and spins around.
A sense-stimulating aid: Protac Ball Cushion
Observed effect: The girl started sitting more calmly from day one. After a few days, it was clear that she could concentrate for longer periods of time and could sit quietly in her chair. She never lays across the table anymore. The girl can also tell the the cushion is helping her. When she arrives in the morning, she is normally the first to take her seat. If she plays on the computer or sits in a different plays than she usually does, she goes off with her chair and cushion.
