Defying the laws of physics, going beyond what we normally understand by the conditions of equilibrium, this bookcase is nothing short of a manifesto for Cassina’s design and construction capabilities.‎ After a lengthy period of research and development, ably assisted by state-of-the-art technology, the company’s designers created a production prototype of the original 1940 piece that architect Franco Albini made as a one-off for his Milan home.‎ Respecting the authentic underlying concept of the design, with its compelling experimental feel, as well as its surprisingly spare, linear looks, today’s model preserves the minimal ideal of the original: a feeling of air and light so that the books and objets seem to float free.‎ Thus does Cassina restore to the contemporary world of design one of its most emblematic artefacts, a piece that has acquired the status of a work of art, as magical now as it was when it was first seen.‎Base· MDF panel, ash sheers thickness mm 1, frame in massive ash wood.‎· Metal rod frame powder lacquered matt black.‎Shelves· Extra light tempered and layered glass, polish edge (thickness mm 7).‎Uprights and shelves crossboards· Massive ash woodExternal braces and glass shelves support braces· stainless steel rod.‎Hardware for assembling· Satined and matt lacquered brass· AVP chemical finishing hematite colour.‎Wooden parts finishing· Natural: matt finishing.‎Finishes:- uprights and base in natural-stained ash, shelves in tempered and laminated glass, metal parts in brass- uprights and base in black-stained ash, shelves in tempered and laminated glass, metal parts in brass with satin chrome finish
