Herman Miller Aeron Buying Guide: Sizes, Features and What to Check

The Herman Miller Aeron is one of the best-known ergonomic office chairs, designed by Don Chadwick and Bill Stumpf and introduced in 1994. Because it is widely resold, many buyers consider a used one. This guide explains what to look at so you can judge a chair properly. For exact specifications, always compare against Herman Miller's own published information.

Choosing the right size

The Aeron has been made in three sizes, commonly known as A, B and C, running from smaller to larger. Size affects seat width, seat depth and how the back and arms fit your body. A chair that is too large or too small can feel uncomfortable even if it is in excellent condition.

• Ask the seller which size the chair is, and ask for a photo of the label or marking that confirms it.
• Check Herman Miller's current size guidance for body size before choosing.
• If several people will share the chair, a mid-range size is often easier to adapt, but test it with the main users if you can.

Classic and Remastered versions

You will see used Aerons described as "Classic" or "Remastered." Herman Miller updated the design around 2016, with changes including its back support and mesh. Because details differ between versions and configurations, treat the description as a starting point and verify it.

Features and adjustments to test

Depending on configuration, an Aeron can offer height adjustment, tilt with tension control, tilt lock or limiter, adjustable arms and back support. Test every control on the specific chair rather than assuming it has them.

• Raise and lower the seat several times and check it holds its height.
• Recline and use the tension control; the movement should be smooth and the lock should hold.
• Adjust the armrests through their full range and check for cracks or loose pads.
• If the chair has lumbar or back support, check it is present and works.

Condition checks

• Mesh: look for sagging, stretched areas, tears or heavy discolouration on the seat and back.
• Frame and base: no cracks, no wobble, and casters that roll cleanly.
• Arm pads: worn or split pads are common on heavily used chairs.
• Noise: creaking or clicking on tilt can point to mechanism wear.

Authenticity considerations

Because the Aeron is well known, lookalikes exist. Reduce the risk by asking for clear photos of the branding and the labels on the chair, comparing them with Herman Miller's official images, and being cautious if a seller cannot show them. If something does not match what you expect, ask more questions before paying.

Questions to ask the seller

• Which version and size is it, and can you show the label?
• Do all adjustments work? Has anything been repaired or replaced?
• How many chairs are available, and are they the same size and version?
• Where is the chair, and is delivery or collection possible?
