Provide a quiet, non-disruptive way for kids (and adults) to release energy with Bouncybands. Made from heavy-duty, latex-free rubber, Bouncybands attach to the legs of a chair and offer a place for feet to rest. Helps relieve anxiety and stress, plus allows active students to stay on task and be more productive, since they can stretch and move while staying seated. Black bands come with support pipes, so they resist sliding down chair legs. One band and two support pipes per package. Band is 13-1/2" long, for chairs with legs that are 13" to 17" apart. Chair not included.
