I have also made several of these Philadelphia wing chairs with a trifed foot. Other frames ready for upholstery that I make include a wing chair with a Marlborough base and a serpentine front camelback sofa with a Marlborough base, pictured below. The sofa originally would probably have been upholstered with a 'tight' seat instead of the cushion. The cushion provides a softer seat but I feel that it detracts from the graceful lines of the piece.
