This board is a new and unique balancing board for play and rehabilitation, and consists of a hard plastic surface with non-skid elevations in artificial rubber to give a good foothold. Low air pressure makes the board soft so that it moves slowly and thereby becomes less challenging for motor functions while high air pressure makes the board hard and lively which makes great demands on motor functions. A standard ball pump (included) is used to inflate the balancing board. Can support weights up to 180 lbs. Grades PreK&up. Ages 3+.
