This is a Pearson Executive Chair, originally designed by Max Pearson in 1966. These particular examples were produced by Knoll in the USA in the 1980s. The chair's design features a channel-stitched padded upholstered seat, and sits on an X-form base with casters. The listed price includes one chair and there are four available to purchase. Each chair measures 27 inches deep, 27.75 inches wide, and 34.5 inches high with a seat height is 18 inches. Some light wear can be seen on the fabric and the bases of the chairs, but overall they are in very good condition. There is some mohair worn away on the arms and front of one. Please see photos. They could be used as/is or would be nice candidates for reupholstery also.
