The half-century of architect-designed task chairs runs on a single commercial premise: that a named author — usually trained as an architect or an engineer, occasionally as both — can move an ergonomic office chair from the procurement page into the design press. The lineage begins on 1 January 1976, when Herman Miller shipped Bill Stumpf’s Ergon, the first mass-market task chair marketed on the basis of medical research. It closes, for the moment, in June 2026, when Foster + Partners premiered the Muku for the Japanese manufacturer Okamura — fifty years and four months later, an architect’s office attaching its signature to a recycled-aluminium structure with a mesh upholstery woven from discarded fishing nets. Between those two endpoints, the architect-designed task chair has been the most reliable category in office furniture by which a manufacturer purchases legitimacy. This piece catalogues every named-author chair in that window: nine principal projects, four manufacturers, eight credited designers, and one consistent commercial argument. ...

Herman Miller’s 2026 Aeron — the first full redesign of Bill Stumpf and Don Chadwick’s 1994 task chair, announced on 2 June 2026 at $2,285 — closes a 30-year run of nine million units sold and reopens the ergonomic office chair lineage that Knoll, Vitra and Steelcase have been ranged against since the Eameses’ 1958 Aluminum Group. The new Aeron lands at Fulton Market Design Days in Chicago, 8–10 June 2026, and is the clearest reset of the category since the original Aeron entered the Museum of Modern Art’s permanent collection in 1994, before it had even reached retail floors. Read backwards from that date, the lineage gathers four manufacturers — Herman Miller (founded 1905 in Zeeland, Michigan as Star Furniture Co.), Knoll, Vitra and Steelcase (founded 1912 in Grand Rapids) — and roughly a dozen designers who fixed what a seated body could expect from an office. ...
