Textiles

The suspension seats and back on Aeron chair are made from Herman Miller’s 8Z Pellicle range of textiles. Used across the various colour options available for the Aeron, this includes Black 23105 (Onyx), Carbon 23102, Graphite 23103 and Mineral 23101.

Finishes

Available in 4 distinct colour shades, the Aeron chair from Herman Miller can be finely tuned to your office environment. The colour palette of the office chair was created thoughtfully, allowing it to blend in wherever they are placed.

Aeron Chair Features

PostureFit SL

This advanced support system helps maintain your spine’s natural S-shape. A stabilising sacral pad supports the base of your spine, while an upper pad reinforces the lumbar area. Together, they work to encourage healthier posture during long hours of seated work.

8Z Pellicle Suspension

The elastomeric suspension distributes weight evenly and adjusts dynamically to your movement. It supports you where it counts and relieves pressure where it doesn’t, improving circulation and all-day comfort.

Harmonic 2 Tilt Mechanism

The next-generation tilt mechanism encourages smooth, balanced movement and natural alignment. Whether reclining or leaning forward, Harmonic 2 ensures consistent support and control.

  • Standard Tilt: Balanced and natural recline
  • Tilt Limiter: Locks the recline angle at set positions
  • Tilt Limiter with Seat Angle: Adds forward tilt functionality for task-focused posture

Three Size Options (A, B, C)

Aeron isn’t one-size-fits-all. It comes in three sizes to provide a tailored ergonomic experience:

  • Size A: Ideal for smaller users
  • Size B: The most popular and widely fitting size
  • Size C: Designed for taller or broader users

Each size varies subtly in seat width, backrest height, tilt tension, and base diameter for optimal fit.

Size Height Range Weight Limit Key Dimensions
A 4’8″–5’4″ Up to 136 kg Compact frame
B 5’2″–6’0″ Up to 159 kg Best for most users
C 5’10″–6’7″ Up to 159 kg Tallest / broadest frame

Tip: Leave 2–3 finger-widths between the seat edge and the back of your knees for proper fit.
