Vestil CPRO-600 Ergonomic Work Seat / Chair
The Ergonomic Worker Seat allows individuals to go from a low crouch position to a standing position. The seat height can be adjusted by moving the seat and hooking in to the horizontal bars located on the chair frame. The unit has 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.
