Petra is a free-standing bookshelf system that combines elegance and lightness, designed to create compositions with a graphic essence. This bookcase offers versatility and customization, adapting to any environment with its compositional freedom. The structure, defined by hexagonal aluminum uprights with a matt gold finish, alternates tempered bronze sandblasted glass shelves decorated with a refined geometric pattern and solid multilayer trays with a dark-stained ash finish. Completing the design are brass shelf brackets and feet, adding a touch of luxury and solidity. This system blends artisanal refinement and contemporary functionality, making it ideal for modern, sophisticated spaces.
