The Echo Lockers containers retake the Dieffebi concept of the modular container but interrpret it with unprededented modes and functions that allow not only to overcome a traditional and anonymous “filling cabinet effect”, but also to integrate this piece of furnitur in the most diverse situations of use and setting: from smart office to coworking, from hotels to pubblic places, from libraries to gyms, and many more. This new system integrates a series of aesthetic, technological, and compositional solutions that make it a versatile tool for containing, furnishing, organizing space and facilitating operativity, in an ideal synthesis of privacy, sharing, and security.
