What We Like

A forward and rear knee tilt is listed, and its tension can be adjusted.
The back is named as 8Z Pellicle elastomeric suspension, and the seat upholstery is listed as mesh.

Watch Out For

The 4.5 rating rests on 2 reviews, so it says little yet about how the chair holds up.
Weight capacity is not stated anywhere in the listing.
The Comfort Index is 12, tied for sixth-lowest in its category: cushion, thickness, recline, breathability and headrest contribute zero, while arms add 10 and the rating 2.

At a Glance

A Graphite Aeron in Size B whose warranty note splits service cover from mechanical cover, with a suspension back.

Who This Chair Is For

Aeron shoppers who want the Graphite finish named in the title.
Sitters who prefer a mesh seat over padded upholstery.

Who Should Look Elsewhere

Buyers who want pivot or width control on the arms, since the listing does not state either.
Anyone who wants a chair that has not been repackaged, since the title says so.

Graphite Aeron: knee tilt, a 17 inch seat and an aluminum base

The tilt moves forward and back as a knee tilt, with adjustable tension. The seat is 17 inches deep by the manufacturer spec sheet, and the listing does not state a seat depth adjustment. The lumbar is described only as an adjustable back support. The base is aluminum and the casters are nylon.

Frequently Asked Questions

What separates the Graphite Aeron from the Renewed one?

The Renewed listing carries a 10-year warranty and arms that pivot. The Graphite one is repackaged, splits its warranty note into service and mechanical parts, and states height adjustment for the arms.

Which dimensions come from the manufacturer?

The manufacturer spec sheet gives a 17 inch seat depth and a 36.8 inch minimum overall height; the listing puts the maximum overall height at 41.25 inches.
