Children and adults have so much fun with this balance board that they are unaware of how good it is for them. While they maneuver the balls along the groove they are developing balance, coordination, determination and patience. Move the balls from the outer circle to the middle, or for a little easier goal...move the balls from the inside to the outside. Made in the USA from durable plywood protected with an attractive laminate. Can hold adults up to 275lbs. Kids 6 - 96 will love it!
