Wide 5-1/2" (14 cm) x 1" (3 cm) thick platforms help prevent tipping and have no foot straps to bind the feet. Features artwork printed on each set so students know where to stand. Foam-padded platform bottoms protect your floors. A combination of lengths will keep the whole class moving. For indoor use only.
