These are Eames Aluminum Group Executive Desk Chairs, initially designed by Charles and Ray Eames for Herman Miller in 1958. These particular examples date to 2010. The listed price includes one chair, and we have two chairs available for individual purchase. Their design features an adjustable aluminum 5-star base with a 360-degree swivel, and their upholstery is done in black Naugahyde. Each chair measures 17.75 inches deep, 23 inches wide, and is 38.75 inches tall, adjustable to 41.75 inches tall. The seat height at the lowest level is 18 inches, adjustable up to 21 inches. There are some light scratches and scuffs to the bases and some wear apparent at the naugahyde’s corners and edges. The arms look near immaculate. Overall, these chairs are in very good condition with light wear. Please see photos.
