No other chair I've found is as flexible (or looks as interesting) as the Swopper. Occasionally if you need a change you can spin the dials on the base to adjust the bounce and tilt. Thumbs up. Blurb:
- Allows you to sit in motion with freedom of movement.
- Bounces and moves in all directions to enhance circulation and spinal fluidity and flexibility.
- Improves posture, abdominal strength, and lower back strength.
- Raises and lowers to work for any height individual or work station.
- Stylish design featured in the New York Museum of Modern Art.
