A flexible bookcase with a dual function – as an element for subdividing internal space or as a wall-mounted bookcase –characteristic for the patterns of variable transparency attained by means of sliding aluminium units. The alternating volumes and spaces and the chromatically offset vertical units give this bookcase a highly dynamic appearance, recalling a totem. The piece represents an ideal synthesis of the designer's research on storage units and of her spirit that links functionality to plasticity, often featured in her work. This bookcase has never previously been put into production. It is available in two versions, high and low, with shelves in natural oak and vertical partitions enamelled in black and white.
