Molded rosewood plywood and down-filled leather — the chief pilot's reading chair, and later the CEO's.
Construction
Three curved plywood shells veneered originally in Brazilian rosewood (later walnut after the 1992 CITES listing), suspended on a die-cast aluminum base, with leather cushions over latex foam and goose down. The shells are formed under heat and pressure in the same five-axis presses the Eames studio developed for wartime leg splints — the production line, in a real sense, never converted from military work.
The proportions
The 670 sits low — only 32 inches tall at the back — and reclines slightly. Charles described the goal as the 'warm receptive look of a well-used first baseman's mitt.' Every dimension was reverse-engineered from that sentence: the cushion depth chosen so the sitter sank rather than perched, the headrest angled for reading rather than dictation, the swivel light enough to turn with a bare foot.
In the executive office
Boeing and Douglas executives kept 670s beside their desks for off-the-record briefings. The chair carried the same engineered aura as the aircraft they were selling — a closed loop of mid-century American confidence in aluminum, plywood, and the men who knew what to do with both.
The counterfeits
By the 1990s, the 670 was the most-knocked-off chair in the world. Italian, Chinese, and US replicas flooded the market at a third of the genuine price. Herman Miller fought a long, partly successful trade-dress campaign through the 2000s, but the design's uncopyrightable silhouette means most knockoffs still ship freely. A genuine chair carries an embossed medallion under the seat — and, increasingly, a holographic authentication chip.
A gift, not a brief
The 670 was conceived as a personal gift for filmmaker Billy Wilder. Herman Miller put it into production within a year, and it has never left the catalogue. The original gift chair, in walnut and black leather, is now in the collection of the Vitra Design Museum.
