Conservators treating 19th and 20th-century upholstered furniture frequently confront sears with broken (jute) webbing and unsupported springs or seats with stretched and weakened webbing. Traditional methods of repairing spring seats did not preserve all upholstery materials. As emphasis on the conservation of upholstered furniture developed, conservators devised alternative approaches to supporting sprung seats. In line with current conservation ethics, these newer approaches are a minimally interventive as possible. This paper focuses on methods of supporting sprung seats that have been used in the textile and furniture conservation labs at Peebles Island Resource Center (New York State Office of Parks, Recreation and Historic Preservation) for seating furniture in the collections of the New York State Historic Sites. The paper traces and credits inspirations for these methods and presents some solutions developed in other labs.
