This little volcano is about to erupt! Our Rocking Volcano has an arc-shaped bottom, which allows kids to move, wobble, swing and rotate all while maintaining body balance. Balancing on the Volcano enhances children’s muscle strength, core strength, posture, and improves concentration. The seat is also patterned to give a sensory experience! The Rocking Volcano transforms conventional sitting into a fun activity by providing an outlet for children to move around while remaining seated. For children ages 3 yrs. +.
