The Herman Miller Aeron Chair is one of the top selling office chairs of all time, and continues it’s popularity even 20 years after it was introduced in 1994. Utilizing it’s highly recognizable ‘pellicle’ mesh, the Aeron has stood out from the crowd and started a trend in mesh back chairs that continues on to this day.

Beyond it’s distinctive design, the Aeron chair has an environmental story that includes using recycled parts and materials, and claims 94% of the chair is recyclable at the end of it’s life (which can be 20+ years if properly maintained), which makes it fit in quite well here at Crandall Office Furniture.

While this is nothing definitive, it should be a good place to start. As always, here at Crandall Office Furniture, we recommend you sit in a chair before you know what model and size are right for you. Chairs are a very individual thing and different people prefer different chairs and features to others.

Identify the Size of Your Aeron Chair

It’s very easy to identify what size Herman Miller Aeron chair you have. Under the top edge of the back frame on the chair (pictured), directly opposite of the Herman Miller Logo, you should feel either 1, 2, or 3 raised dots similar to braille (pictured) that indicate the size of the chair you’ve got. If your chair does not have any dots, or you can’t find them, feel free to reach out to one of our chair experts for help.

1 dot = A Size Aeron
2 dots = B Size Aeron
3 dots = C Size Aeron
