Salli SwingFit Ergonomic Saddle Chair or Stool - SS-SF
The swing mechanism of Salli SwingFit Saddle chair enables the seat to be tilted in every direction without a separate adjustment lever. Thus you can exercise while sitting, which adds to the mobility and metabolism of the lower back, and activates the whole body.
Rocking seat adjusts to the movements of the body. Even small movements stimulate muscles in the abdominal and pelvic area, similar to sitting on a gym ball.
