Four Knoll Pollock Chairs in great condition. Vintage 1985, black leather, swivel base, original tags. Sold as a set. Charles Pollock went to Pratt in the 1950’s and opened his first design studio in Brooklyn where he created his first chair for Knoll. So these chairs are great examples of an earlier wave of Brooklyn leading the wave of innovation and great design. The chairs are all black and the same color like the photo of the individual chair. The difference in color in the group photo is due to bad lighting and my iphone.
