Transform a standard school chair into a Wobble Chair enabling kids to have an outlet for excess energy while working, alleviating anxiety, hyperactivity and boredom. Kids can rock back, forth and all around as the continuous movement increases blood flow to the brain enabling a greater ability to focus. Installation is simple as each foot snaps right onto the standard round school chair glide. Feet measure 66mm H and 396.5mm dia. Can be used on tile, wood, and carpeted floors. Not a toy – adult supervision required.
