Sensory spinning play on this elephant swivel chair encourages kids to move as they sit, lie down or kneel on the molded PP seat. The 21 x 19.5 x 10 in overall size and 20 x 19.5 in seat give children room to shift positions while they rotate. A curved ergonomic seat helps engage core muscles and support balance during motion. Ball bearings in the heavy-duty metal base create smooth, quiet 360° spinning, and non-slip foot pads add stability while supporting up to 220 lbs for kids ages 3 and up.
