Swiveling Parchment Fiberglass Arm Chair by Charles & Ray Eames for Herman Miller An original and highly desirable 1960s edition, this chair features a parchment fiberglass shell with a swiveling, height-adjustable base. Marked Herman Miller under the seat, it represents an authentic piece of mid-century design history by Charles and Ray Eames. Eames Fiberglass Shell Chairs First introduced in 1950, the Eames fiberglass shell chairs were the world’s first mass-produced chairs made from fiberglass-reinforced plastic. Designed by Charles and Ray Eames for Herman Miller, the shells combined modern materials with an organic, ergonomic form that could be adapted to a wide variety of bases—creating a truly versatile seating system. The chairs were originally available in a limited palette of colors, but quickly expanded to include a range of shades, finishes, and upholstery options. Highly collectible today, vintage examples are especially prized for their distinctive fiberglass texture and patina that develops with age.
