Exercise the balance chair

Designers can really toss, design such a chair exercise people's sense of balance chair.

The seat cushion of the chair is not fixed, but supported by a central shaft. People sitting up will only shake around, even if not shake or spend a lot of strength, its uncomfortable degree is not pressure and squatting. Dare you ask who is not sitting in the chair to rest? The best way to work on your balance is to walk on the balance beam.
