Duverneuil Louis Philippe swivel chair on balls

Louis Philippe period armchair stamped by Maison Duverneuil (see photo) Swivel seat system on balls patented in France and abroad by SGDG. In blond walnut. Canework in good condition. Rare office chair with all the elegance with its curved back and its crooked armrests tilting on the outside, very wide seat, the ancestor of our insignificant office chairs on casters, a beautiful piece that reminds us again how much refinement was in fashion at that time.
