Not sure what size chair is right for you? Read on!


The Herman Miller debuted in 1994 and since then Herman Miller have continue to refine and improve this classic ergonomic chair whilst still maintaining its iconic look. We at Griffin Office Solutions are proud stockists of used Herman Miller Aeron chairs. Did you know that we often have Aeron chair in different sizes and have you ever wondered which size Herman Miller Aeron Chair would suit you?!

Did you know that the Aeron chair comes in three sizing options –

  • Size A
  • Size B
  • Size C

Size B is the most popular option and the size that we most frequently stock. We occasionally have size C and A in stock.

In this blog we will be showing you how to use the “Size/Fit reference” chart for the classic Aeron chair.

This reference helps people select A-, B-, or C-size chairs when the three sizes are not available for actual test sitting or you can’t make it to our showroom in Athlone.

Height and weight are key indicators of suitable chair-size choice. Since the B-size chair is designed to fit a broad range of people, Herman Miller recommends it for users who fall in the A/B or B/C category. This chart applies to Classic Aeron chairs with the extended-height-range pneumatic height- adjustment cylinder.

To determine which chair size is best, find the point of intersection for your height and weight. Classic Aeron A-, B-, and C-size chairs are tested and warranted for use by persons 300 pounds and under.

If you have any questions please do not hesitate to contact us and of course you are welcome to try “one on” to fit if you would like to visit our showroom which is now open to the public in Athlone, Co. Westmeath.
