The Sit-Stand Arm has been designed to provide better ergonomic support in both seated and standing positions. The design provides comfort by moving the user closer to the work surface. These arms are ANSI/HFES, 100-2007 and BIFMA G1-2002 compliant by meeting the adjustment guidelines for users from the 5th percentile female seated to the 95th percentile male seated, while conforming to the operator's knee-clearance requirements. The Ovation arms use our patented Lift-N-Lock™ technology in a concealed brake mechanism for superior lock-up and stability and includes the patented Dial-a-Tilt technology with both height and tilt gauges. Designed and manufactured in the USA for TAA and BAA compliance, these arms have a great range of motion.
