In just a few simple movements, the Sedia3 chair can be transforms from 3D to 2D for easy storage, portability, and space-saving. Lifting the seat surface from the rear and pushing it towards the front releases the legs and the central crosspieces. Then, the chair can be folded flat. No tools are required! This versatile design is composed of wood with the exception of the rear metallic pivot pin and hook that makes it possible to hang on the wall, completely out of the way.
