Swopper is a revolutionary new concept in sitting. Swopper allows the user to access motion during a seated task. What was once static and motionless in a chair becomes fluid, energized movement on Swopper. Swopper allows you to tilt, sway and bounce simultaneously. This natural, fluid motion gives you access to several amazing health benefits: keeping spinal joints lubricated, maintaining proper postural alignment (conventional "static" seating often only serves to "de-condition" the intrinsic muscles of the spine and back by restricting motion), and promoting spinal mobility (keeping the natural forward curve).

Adjustment Features: Seat Height 22" to 27 1/2" (with no one on seat)

Spring Tension: the "bounce" in the seat is adjustable for people up to 290 lbs.

Lateral Movement: the range of motion (from side to side, forwards and backwards) can be adjusted to suit your individual need and comfort.
