the.com/office chair

means A wheeled, adjustable chair designed for desk work, built to swivel, roll, and support hours of sitting.

from The word 'chair' traces back through Old French 'chaiere' to Latin 'cathedra' (seat), the same root that gives us 'cathedral' — a seat of authority. 'Office' comes from Latin 'officium,' meaning duty or service. The modern office chair itself is a 19th and 20th-century invention: the swivel chair is often credited to Thomas Jefferson's tinkering, and the ergonomic, wheeled version we know today emerged with the rise of the modern office and typewriter-era clerical work, as designers raced to keep bodies upright and productive for longer stretches.
