From a low crouch to a standing position, the seat height of the CPRO-200 can be adjusted in 2" increments by removing the seat and hooking it to the horizontal bars located on the chair frame. These units have four rubber "shocks" under the seat base that allow the seat to tilt forward, left, and right so it can accommodate your body movements. The front tilted position of the seat helps the user maintain the natural posture position of the spine.
