Description: This vintage Cosco Model 15-F Secretarial Posture Chair, produced by Hamilton Manufacturing Co. in the 1950s, exemplifies the durability and sleek functionality of American industrial design. Constructed from steel with its original textured vinyl upholstery, this chair was built for office efficiency and comfort. The five-star base with casters ensures mobility, while the adjustable seat and supportive backrest reflect the era’s emphasis on ergonomics. Its minimalist gray finish and rugged build give it a timeless utilitarian appeal that works well in both modern and vintage-inspired interiors. Still in its original vintage condition, the chair shows light wear consistent with age, adding to its authentic charm.
Fun Historical Fact: Cosco, founded in 1939 in Columbus, Indiana, was one of the pioneers in designing mass-produced furniture with a focus on practicality and affordability. Their office chairs were marketed in magazines like Fortune during the 1950s as “Office Fashioned”—a blend of style and engineering aimed at the postwar corporate boom. At just $29.95 when first introduced, the Model 15-F offered an accessible alternative to expensive executive seating, making it a staple in mid-century American offices.
