Abstract
Abstract A balance board structure for recreation or exercising use comprises a roller-supported foot platform having the roller positively retained in a frame under the platform by a retention pin extending through the roller into guide channels formed in opposed longitudinal side members of the frame. In use, the roller is manipulated along the frame by a person standing on the foot platform and the pin prevents separation of the components, for example during transport, or when the user falls off of the foot platform.
