How it's made
US-manufactured, mostly US materials
The Herman Miller Aeron Chair Size B is the world's most recognized ergonomic office chair, designed by Don Chadwick and Bill Stumpf, introduced in 1994, and permanently enshrined in the Smithsonian Institution's collection as a landmark American design achievement. Manufactured in Zeeland, Michigan, the Size B medium fits the widest range of users — 5′2″ to 6′6″ and 130–325 lbs — with 8Z Pellicle mesh that varies tension across 8 zones for precise pressure distribution, PostureFit SL lumbar support that cradles both the sacrum and lumbar spine, and a balanced recline mechanism that keeps the body in natural alignment through every position. Backed by a 12-year, 3-shift warranty and now available with ocean-bound plastic components for enhanced sustainability, it remains the gold standard of performance seating.

Why the USAmade Score™ is 7/10
The Aeron is one of America's most iconic product designs, manufactured at Herman Miller's Zeeland, Michigan facility since 1994 and permanently collected by the Smithsonian Institution, which lists its manufacture as "Zeeland, Michigan, USA". The majority of Aeron components are made in Michigan, with Herman Miller explicitly stating the chair qualifies as "Made in USA" under FTC guidelines due to the majority of component manufacturing occurring in Zeeland. However, some components — notably certain polymer parts and electronic tilt mechanisms — are sourced internationally, and the newer ocean-bound plastic variants incorporate globally recovered materials, which keeps this at a 7.
