Furniture Design R shell 1.0 Chair by Hui-Ju, Chou R Shell is a conceptual designed chair realized in steel and FRP. Its design magnificently mixes natural elements with construction engineering. R Shell is formed by two curve surfaces leaning one against the other; these surfaces support each other and strike the balance between the point, the line, the virtual and the entity surface. One of the two surfaces is constructed with multiple lines. These sinuous lines enchant the eye forming a virtual space that takes visual to another level.
