The Queen Mary Bedroom was used by Queen Mary and King George V when they visited Althorp in 1913. Queen Mary was a dreaded houseguest, with a tendency to hint very heavily that she liked a particular object belonging to her hosts, until they felt obliged to offer it to her as a gift.
The chimneypiece is by Robert Adam. The tapestry work on the chairs was designed and embroidered by the Seventh Earl Spencer who was Chairman of the Royal School of Needlework.
The extremely tall bed is a copy of an eighteenth century design, and is draped in rich green taffeta.
