These extremely comfortable swiveling office chairs are the "Executive Chair", designed by Charles Pollock for Comforto and produced by Knoll International. They are in vintage condition and have some wear and tear from authentic office use. The black leather upholstery has some cracks in it and there are scuffs and scratches throughout. These handsome 1960's stunners are still in usable shape and are worth the effort it would take to restore them to their former glory. I've seen this model in similar shape go for big bucks, so save some money and give them a loving home today!
