How to Confirm Your Aeron Chair Is Size A
Before purchasing, verify your chair size using any of these identifiers:
 
1. Look for the Size Marking Under the Backrest
On Classic Aeron chairs, you’ll find raised dots molded into the plastic frame behind the backrest:
•  1 dot = Size A (Small)
•  2 dots = Size B
•  3 dots = Size C
