The OM5 Series® Work and Active seating all feature “body-activated motion” that was inspired by a desire to create ergonomic seating that is both intuitive and highly responsive. Through precise engineering and well-balanced geometry, all of the seating in the complete OM5 Series® subtly respond to moment-by-moment micro-changes in body position to facilitate mind and body well-being. OM5 Series stacking sled-base chair has an articulating, one-piece nylon shell top. The OM5 Active is available in 8 shell colors and comes standard arm-less, with a black powder-coated or chrome frame. Arms are optional. 12 Year Limited Warranty. (See also these active models: OM5 Cafe Stool and OM5 Guest).
