Eureka Ergonomic ERK-SC-002/SC-001 Swing High-Back Executive Swivel Office Computer Chair with Armrest

The Eureka Ergonomic ERK-SC-002/SC-001 Swing is the only chair in the world where the pivot point of the chair is in the same area as the pivot point (CR-1) of a human's natural seated posture. As Ergonomists certify, the natural pivot point (or Center-of-Rotation (CR-1)) of a human's natural seated posture is proximate to the naval.  The pivot point of all other office chairs is under the seat, at least 6 to 8 inches out of alignment. The Swing Chair is engineered using the most current ergonomic research. The path of motion is the same as that recommended in the HFES-100 Standards (Human Factors Ergonomic Society) and is also certified by ANSI (American National Standards Institute).
