ARC Technology®
The single piece polymer shell features SitOnIt Seating ARC Technology® (Active Rebound Control). A unique insert enables this line of stackable chairs to flex based on the amount of weight pressed against it (weight assisted recline).
The flexor insert – hidden inside the back base – is made from polyoxymethylene (POM). POM is an engineering thermoplastic used in precision parts requiring high stiffness, low friction and excellent dimensional stability. The material is widely used in the automotive and consumer electronics industry. The flexor is securely bolted to the seat frame to endure punishing daily use, yet return to its original shape without fail.
