The Demon Shelving system, or the 'Biblio-Démon' as it is referred to in designer Mathieu Mategot's original sketches, was part of a “plan d’execution de la bibliothèque”; a plan to replicate the style and atmosphere found in library or grand study in the home. Designed by Mategot in 1954, this modular shelving system can be applied in various ways; ideal for storing books, kitchenware or an eclectic mix of personal decorative accessories.

Mathieu Mategot was born in Hungary in 1910. After his studies at the school of fine arts and architecture in Budapest, he began to create sets for the National Theatre. He settled in France in 1931, where he took up various professions, creating sets for the Folies Bergeres, window dresser for the Lafayette Galleries, fashion designer for dressmaking firms in Paris.
The second world war interrupted his activity. A volunteer in the French army, he was taken prisoner and he was free in 1944. After his return, he set up a workshop for hand crafted furniture in Paris. He used materials such as metal, rattan, glass, Formica, and perforated sheet metal in particular, to design chairs, armchairs, tables, serving tables, sideboards, desks and useful articles.
Mathieu Mategot died in February 2001 at Angers, France.
