It is a Classic if bought new before late 2016, with an even mesh weave and a joint with exposed screws behind the seat. Remastered chairs have zoned mesh, a smooth triangular joint and often two lower-back pads. Supports Your Head and Neck: Raise the headrest 6 to 9 inches above the backrest, tilt the cushion 36 degrees and angle the neck joint up to 76 degrees. The hinge locks in place without rattling, so it stays put through long workdays at your desk. Breathable Mesh, Matching Look: Black polyester mesh on a graphite nylon frame keeps air moving and blends in with the original Classic Aeron finish. A removable coat hanger on the back keeps your jacket off the floor and wrinkle-free. Easy, Scratch-Free Install: Attaches to the Aeron back frame in minutes with the included hardware and instructions. No drilling and no permanent changes to your chair.
