Rex was selected as the winner chair in the design competition, A Chair for the Crown Prince, organized by the Danish Craft and Design Association in 2001. The first Rex Chair was made of molded oak with sealskin upholstery – a reference to the Crown Prince´s love of Artic nature. The chairs unusual shape was made possible by a combination of folds and a vertical slot, where the seat meets the back. The X shape of the swivel base symbolizes the future place of the Crown prince in the Danish royal family line as King Frederik X.
