We have two Danish modern armchairs, family heirlooms that my parents purchased when stationed in Copenhagen in the 1960's. The chairs were much loved albeit much the worse for wear. The suspension system, steel springs mounted in a tubular steel frame, is apparently unique. No one in Ontario whom we spoke to had seen it before, not even Johnny! No one else would take on the project ... except Johnny. Johnny came in on time and on budget. We are thrilled with the results! Our children and their children will enjoy these chairs for the next 60 years! And more!
