The Spinning Board is a tool that is both fun and useful. It is used in homes and by therapists to help children get the rotary input they need. Some children spin as a way to calm and self-regulate. This will help them do that more efficiently and constructively. The Spinning Board is made of 100% Baltic Birch and carpeted for extra comfort, also with handles for safety. It measures 25" in diameter. The Spinning Board has a weight limit of 150 lbs.
