Kore Design Teen/College Adjustable Wobble Chair, Black

Great for active students, this chair lets you rock as you study or play video games to keep your core muscles engaged and help you focus. The ergonomic design provides a comfortable place to sit, and the rubberized coating is skid resistant. Weight capacity tested to support 350 lb. Made of tough steel, chrome, PVC and high-density polyethylene for a strong design. Anti-tip ring on base prevents tip-overs. Non-skid, rubberized coating offers grip to prevent sliding. Scratch-resistant for durability. Rounded, ergonomic base creates a wobbly design, so you can move freely. Rock and swivel to engage leg, back and abdominal muscles. Counter-balanced, so you can sit upright without rocking. Quick and easy assembly required.
