Sharp modern design classic, designed by Charles Pollock for Knoll, circa 1980's. Known as the Executive Chair, this iconic example features a tufted black leather seat and back rest, black plastic arms, and a plastic shell frame with chrome trim. The swivel bucket seat is attached to a center pole, which is mounted on a polished aluminum base, with feet. All 4 are in very good, clean, ready to use condition, showing only light cosmetic wear, normal and consistent with age.
