The special wobble stool provides kids with more fun and transforms boring and sedentary sitting into dynamic activity. Kids can teeter, totter, jiggle and sway all day on the chair while having their works done. Also, flexible sitting can release fatigue and engage the core naturally for the right sitting position. Both cushion and the bottom are made of soft and non-skid silicone gel, which strikes the perfect balance between a comfortable sitting experience and high stability.
