herman miller altissimo Herman Miller Aeron Chair, Size A

The Aeron Chair revolutionized office seating with its defining design qualities: the pioneering 8Z Pellicle suspension material and the patented PostureFit SL back support, which provide the ideal sitting position—chest open, shoulders back, and pelvis slightly tilted forward. Combining a deep knowledge of human-centered design with cutting-edge technology, the Aeron Chair is engineered with state-of-the-art adjustability, including the arms, seat height, depth, and recline, to help you maintain optimal posture so you can focus on the task at hand. It’s offered in three sizes to provide the greatest comfort for the widest range of users.

• Breathable suspension keeps you cool and comfortable.
  
• Three chair sizes deliver comfort to nearly every body type.
  
• Adjustable PostureFit SL pads provide lumbar support and stabilize the base of the spine.
  
• Harmonic tilt supports the way you naturally move for a smooth and balanced recline.
  
• Fully adjustable arms (height, depth, and angle) allow for a custom fit.
  
• Composed of recycled materials, Aeron's production helps divert plastic waste from the ocean.

Aeron is up to 91% recyclable based on available recycling facilities. Aeron is composed of more than 50% recycled material, including ocean-bound plastic. Aeron is BIFMA Level 3 certified and has also received the Indoor Advantage Gold certification, SCS Global Services' highest level of indoor air quality performance for furniture. The certification ensures that furniture products support a healthy indoor environment by meeting strict chemical emission limits for volatile organic compounds (VOCs).
