These replacement seat pans for the Aeron Chair are original OEM. If you love your Herman Miller Aeron Chair and just need a new seat because the fabric is worn torn or damaged then we have your solution!
Be sure to check your Aeron's size before ordering.
Aeron chairs come in three sizes- A, B, and C. A is the smallest, and C is the largest. You can determine the size of your chair by feeling underneath the plastic rim of the top of the chairback. You will feel a bump or several bumps. One dot means you have a size A chair, TWO dots for B, and THREE dots in a triangle for C.
An alternative method to determine your Aeron's size is by turning your chair over and looking on the manufacturer tag. There will be a model number like this: AE...W_............ In this example, the letter that appears after the "W" is your chair size.
Dimensions for size C:
Width 21.5" Depth 19.5"

Installation instructions: You can install a seat with two 3/8" ratchets, a 10mm socket, a 4mm allen socket attachment (for attaching the two seat links at the lower back of the seat), and a 6mm socket attachment to install the two upper hip bolts on each side and the two lower tilt bolts. These can be purchased at any Sears. You don't need a torque wrench, just don't over tighten the bolts.
