Herman Miller Aeron Onyx vs Graphite

The Herman Miller Graphite Aeron features a dark grey finish, whereas the Onyx has an ultra-matte ‘true black’ finish. If you’re looking for a perfect contrast with white office furniture, the Onyx offers the most striking effect, with the chairs silhouette standing out effortlessly against the lighter tones of the rest of the work environment. The Aeron in Onyx also includes over 1kg/2.5lbs of ocean bound plastics (OBP).

What is the difference between the BK and BLX finishes used by Herman Miller?

BLX is the premium ultra-black finish used on Onyx painted die cast components. BK refers to injection moulded components which are considered the ‘standard black’ finish.

Is the Ultra-Matte finish of the Onyx just for aesthetics or a reflection of the quality of the materials used?

Is the Onyx Ultra Matte BLX worth it? Absolutely and on both counts of aesthetics and quality. Onyx gives the Aeron a bold refresh with a striking, high-contrast look that grabs attention right away. Inspired by modern design trends, this rich, ultra-matte black shade and its sleek texture move our iconic chair forward. Plus, ocean-bound plastic has been integrated into the tilt cover and frame. Darker colours make it easier to include more of this sustainable material, which is why Onyx features the highest amount of ocean-bound plastic.

What other Herman Miller components feature the Onyx BLX Ultra Matte finish?

Along with Aeron chairs, the Onyx finish can be found in the Herman Miller Bay Work Pod (Door Frame & Handle), along with the legs of the Herman Miller Cyclade tables.

What is the difference between the standard Herman Miller Onyx Aeron and the Executive Onyx Aeron?

The standard Onyx Aeron features the deep black finish across the whole chair. The Executive version features a polished aluminium frame and base, providing a luxurious contrast between them and the main body of the chair.
