Antonio Citterio has long been drawn to systems that think. The Infinity Bookshelf for Flexform is among his most resolved: freely stackable metal modules, finished in epoxy powder coat, that organize themselves around the logic of a room rather than against it. Geometry is the constant. Configuration is the variable. Each arrangement shifts the visual weight of the piece, whether it reads as a quiet grid dissolving into a wall or a considered architectural presence commanding a room's center. Modular epoxy-powder-coated metal construction Freely stackable modules for open-ended configuration Extensive color palette spanning neutral to expressive tones Compatible with Flexform cowhide Box containers for concealed storage Suitable for freestanding and wall-adjacent installation The optional cowhide Box containers introduce warmth within the open grid, softening the precision of the metal frame with material contrast. Enclosure and openness exist side by side, each making the other more legible.
