Herman Miller Aeron Chair FAQs

Is Size C the right size for me?

Size C is designed for users approximately 6'1" / 183 cm and taller. If you’ve previously found standard chairs too small or lacking upper back support, Size C is likely the better fit. Need advice? Our team is happy to help.

Is the Aeron chair good for back support?

Aeron’s Pellicle mesh provides breathable comfort, while its multi-zone tension system reduces pressure and delivers targeted support. With PostureFit SL and extensive ergonomic adjustments, the chair is designed to support the natural curve of the spine.

How do you adjust the seat height?

To raise the seat: While not seated, lift the paddle-shaped lever on the right side upward.
To lower the seat: While seated, lift the same lever upward.

Adjust so your feet rest flat on the floor or on a footrest.

How do you adjust the recline tension?

Increase tension: Turn the knob on the right side forward (clockwise).
Decrease tension: Turn the knob backward (counterclockwise).

Adjust to suit your preference.

What warranty does the Aeron chair include?

Herman Miller provides a 12-year warranty covering parts and labour when purchased from an authorised retailer such as Wellworking.

Does the chair require assembly?

The Aeron arrives fully assembled and ready to use, unless knock-down delivery is specifically requested.
