The Herman Miller Aeron is the world's most recognised ergonomic office chair, and for good reason. Originally designed in 1994 by Don Chadwick and Bill Stumpf, the Aeron Remastered builds on three decades of refinement with 8Z Pellicle mesh, PostureFit SL spinal support, and a Harmonic 2 tilt mechanism that responds to your body weight automatically.
Every Aeron at Chair Dinkum is a genuine Herman Miller product sourced as a parallel import, which is how we offer them at significantly less than standard Australian retail. Available in three sizes (A, B, and C) and six colour options, there is an Aeron to suit every body type and workspace.
Who is the Aeron best for?
The Aeron works best for:
- All-day sitters (6-10+ hours) who need consistent support without heat buildup, because the full mesh design keeps you cool even in Australian summers.
- People with lower back pain or posture concerns who need adjustable sacral and lumbar support, because PostureFit SL targets both regions independently.
- Home office workers who want a chair that will last 12+ years of daily use, backed by a comprehensive warranty.
- Office managers and fit-out buyers furnishing multiple workstations with a proven, durable chair that suits a wide range of body types across three sizes.
The Aeron may not suit you if you prefer a cushioned, padded seat feel (mesh is firm and supportive, not plush), or if you need a chair with a built-in headrest (the Aeron does not include one as standard).

Frequently asked questions
Is this a genuine Herman Miller Aeron chair?
Yes. Every Aeron we sell is a genuine Herman Miller product. We source them as international parallel imports, which is how we offer them at significantly less than standard Australian retail pricing. The chairs are identical in every way to those sold through authorised dealers. Warranty support is provided directly by Chair Dinkum.
What size Aeron should I get?
The Aeron comes in three sizes. Size A (Small) suits people 142-165 cm tall and 41-68 kg. Size B (Medium) suits 163-180 cm and 59-104 kg, and fits approximately 80% of users. Size C (Large) suits 178-201 cm and 82-136 kg. If you fall between sizes, we recommend trying both in our Sydney showroom or calling us on 02 9640 0642 for advice based on your build.
What is the difference between PostureFit SL and adjustable lumbar?
PostureFit SL uses two independent pads that support both your sacrum (base of spine) and lumbar (lower back) region, encouraging a natural forward pelvic tilt. Adjustable lumbar is a single height-adjustable pad that supports only the lumbar area. PostureFit SL is generally preferred for all-day sitting because it provides more complete lower back support and helps maintain proper spinal alignment throughout the day.
How does the Aeron compare to other ergonomic chairs?
The Aeron's full mesh design makes it the best choice for people who run warm or work in hot climates. Its 8Z Pellicle mesh distributes weight across eight zones of varying tension, which no foam seat can replicate. Compared to the Steelcase Leap or HAG Capisco, the Aeron excels at passive cooling and consistent support. It is less suited to people who prefer a soft, cushioned feel. The 12-year warranty is among the longest in the industry.
What is the difference between the Aeron colour options?
Graphite is the classic dark grey finish with the highest recycled content (73%) and our best value from $2,150. Mineral is a lighter, contemporary grey with a satin aluminium base. Onyx is the darkest option with an ultra-matte black finish. Both Mineral and Onyx are available with polished aluminium base upgrades for a more refined look. The mesh, frame, and mechanism are identical across all colours.
Does the Aeron come assembled?
The Aeron arrives mostly assembled. You will need to attach the base with castors, the seat and back unit, and the armrests. This takes approximately 15-20 minutes with no special tools required. Full assembly instructions are included. If you are in the Sydney metro area, we can arrange professional assembly for an additional fee.
How long will an Aeron chair last?
The Aeron is built to last 15-20 years of daily use. The mesh does not compress or sag like foam cushions, and the tilt mechanism is rated for over 100,000 cycles. Herman Miller backs the chair with a 12-year warranty covering defects in materials and workmanship. Many Aeron chairs from the original 1994 design are still in daily use today.
Can I try the Aeron before buying?
Yes. Visit our Sydney showroom to sit in all three sizes and compare colour options in person. We recommend spending at least 15 minutes in the chair to get a proper feel for the support and adjustments. If you cannot visit, call us on 02 9640 0642 and we will help you choose the right size and configuration based on your measurements and preferences.
