The Aeron is the apotheosis of ergonomic seating, conceived to conform not only to different human shapes and weights but also to movement. The breakthrough Kinemat ® tilt enables the Aeron to smoothly move with the sitter from a forward tilt (when you reach for the phone) to a backward recline (while you contemplate what to say). The Pellicle ® web upholstery is yet another innovation both in concept and comfort. It evenly distributes weight over the seat and back and permits air circulation. As for durability, it will look like new long after you retire. Design doesn't get more civilized.See size chart located in "View Detail" to find the best fit for your Aeron Chair.This original is an authentic, fully licensed product of Herman Miller, Inc.
