The Rocket steel bookcase created by Ono Design exemplifies an essential and changeable design that allows multiple possible combinations. Positionable against the wall or in the centre of the room, this modern bookcase is at the service of the surrounding environment with a rigorous yet original aesthetic. Its compact size makes it suitable for a narrow wall, a reading corner or an elegant hallway. However, this design bookcase is highly capacious with seven useful shelves. Furthermore, several modules can be placed side by side, maintaining their direction or rotating them, to create an intriguing geometric composition marked by diagonal cuts and with the shelves visible or hidden to varying degrees. Overall, it is an object that infuses light into the environment and whose design rigour is reduced by the optical effect, which tends to smooth the corners and create the impression of a sinuous spiral bookcase.
