On office chairs.

In the 1950s and '60s, the distinctions between rank found blunt expression in chair design, naming and price point; Knoll, for example, produced "Executive," "Advanced Management," and "Basic Operational" chairs in the late 1970s. Recall the archetypal scenes where the boss, back to the door, protected by an exaggerated, double-spine headrest, slowly swivels around to meet the eyes of his waiting subordinate, impotent in a stationary four-legger.
