Herman Miller Aeron vs Haworth Zody II: Which Should You Buy?

Introduction

The Herman Miller Aeron and Haworth Zody II are both adjustable task chairs, but they differ in sizing, back support and recline. Aeron comes in sizes A, B and C; Zody II is one size, with a dual posture option for higher seat heights. This is a research-based comparison using manufacturer sources, not a hands-on test.

At a glance

Herman Miller Aeron — strengths & weaknesses

Documented features: Aeron comes in sizes A, B and C, with weight capacities of 300, 350 and 400 lb by size. Herman Miller lists the Harmonic 2 tilt, arm options from stationary to fully adjustable, and lumbar options including Adjustable PostureFit SL.

Check before buying: Choose the size first; seat height differs by size (for example 14.4–19.3 in for size A). Lumbar and arm options vary by configuration, and Herman Miller does not offer a headrest. The US Herman Miller Store lists Aeron at $1,775–$2,840 depending on configuration.

Haworth Zody II — strengths & weaknesses

Documented features: Haworth's PAL (Pelvic and Asymmetrical Lumbar) back lets you adjust lumbar support separately on the left and right. Zody II has 4D arms, adjustable seat depth (76 mm of adjustment in Haworth's Asia Pacific sheet), forward tilt and a dual posture option for sit-to-stand use.

Check before buying: Haworth publishes Zody II specifications by market, and the US Haworth Store sells a chair named "Zody Office Chair" rather than Zody II. The weight capacity is listed as under 181 kg in Asia Pacific and under 150 kg in EMEA, and an adjustable headrest is not yet generally available.

How they differ

Seat height: Aeron's seat height depends on size (14.4–19.3 in for size A, 14.8–22.8 in for size B, 15.8–22.8 in for size C). Haworth's Asia Pacific sheet lists 406–533 mm (16–21 in) for the Zody II office chair and 445–615 mm (17.5–24.2 in) for dual posture.

Recline: Herman Miller lists the Harmonic 2 tilt, with tilt limiter options. Haworth describes a balanced 3-point tilt in which the back reclines 24° from upright, with a back stop in six positions (upright and every 4°) and forward tilt.

Seat depth: Aeron's seat depth is fixed by size (16, 17 or 18.5 in). Zody II's seat depth adjusts over 427–495 mm (16.8–19.5 in) in Haworth's Asia Pacific sheet.

Lumbar: Zody II's PAL back adjusts left and right lumbar support independently. Aeron's lumbar depends on the option chosen: no additional support, PostureFit, Adjustable Lumbar Support or Adjustable PostureFit SL.

Headrest: Herman Miller does not offer a headrest for Aeron. Haworth lists a Zody II headrest as not yet generally available.

Price: The US Herman Miller Store lists Aeron at $1,775–$2,840 by configuration. Chairpedia has not confirmed a US Zody II price, because the US Haworth Store sells the "Zody Office Chair"; compare delivered quotes for the exact models.

Who should buy which

Consider the Herman Miller Aeron if: you want to choose among three frame sizes with a suspension seat and back, and a headrest is not required.

Consider the Haworth Zody II if: you want independent left and right lumbar adjustment, adjustable seat depth, or a dual posture version for a sit-to-stand desk, and you can confirm the exact model with the seller.

Bottom line

Neither chair is a universal winner. Aeron's fit starts with choosing size A, B or C; Zody II's starts with setting its PAL back and choosing the office chair or dual posture version. Try the exact configuration you plan to buy, and compare delivered price, returns and warranty service.
