Ballo Stool by Humanscale

The exciting and kinetic Ballo Stool features two rounded sides that engage your core while you're sitting down. If you like to move around throughout the day (and it's good for your health to do so), then this chair is exactly what you need. The lack of a backrest and rounded bottom gives the chair an unstable nature which means you have to keep it still. In order to do that, you have to actively concentrate on your posture. You can also dance around, which is awesome. This chair is made for the people who like to stay on the move and don't like to sit still.

Features:

• Lightweight at just 13.5 pounds and with cleverly designed hand holds, Ballo can be easily moved from space to space
• The top and bottom air domes are made from a thermoplastic vulcanizate (TPV) material, rather than PVC that is the industry standard and can off-gas
• Counterweighted base ensures Ballo remains upright for stable movement and convenient storage
