Very little is known about the Portman Upholstery Company other than the superior quality, materials and comfort they offer is only to be rivalled by Howard & Sons. Both companies were in central London W1. It is believed they traded from the 1930’s to 1960’s. Pieces can often be seen in important country houses and stately homes.
