Antique Adjustable Rolling Dental Chair by O.C. White

c. 1910s-1920s; O.C. White Co. - Worcester, MA An early example of O.C. White's precision mechanical craftsmanship, this adjustable dental chair reflects the company's transition from fine industrial lighting and articulating arms into specialized medical and optical furnishings. The chair features a hand-operated adjustable headrest, tilting backrest, and height-variable seat-each locked by tension levers and iron fittings. Its seat and back are upholstered in the original worn leather, exhibiting a rugged, time-softened patina that speaks to decades of clinical use. The cast-iron base rests on four casters, with subtle scrolled bracing that betrays its turn-of-the-century machine-age lineage. O.C. White, established in 1883, became renowned as one of America's earliest manufacturers of adjustable lighting and precision equipment, supplying fixtures and apparatus to dentists, machinists, and laboratories alike.
