BRAND NEW Complete with orignal herman miller warranty. Product information Occupying a place in the Museum of Modern Art's permanent collection, the Aeron is a chair that offers ergonomic comfort while adding a contemporary aesthetic into your home office environment. Thanks to unique design features, this chair adapts naturally to your body type. PostureFit supports the way your pelvis tilts forward naturally, ensuring that your spine stays aligned to avoid back pain and allow you to sit for hours in complete comfort. Along with PostureFit, Aeron’s other ergonomic design features include a high, wide, contoured back that takes the pressure off your lower spine, and slightly sloping armrests to provide natural and comfortable support. The dipped front edge of the seat takes the pressure off your thighs to promote good blood circulation and healthy posture, and thanks to the patented Kinemat tilt mechanism your neck, shoulders, hips, knees and ankles can pivot naturally.
