The project Le Mura by Mario Bellini represents the manifesto of a radical design that went through all the Italian 70s: design was as an answer to questions not only of aesthetics, proportions or ergonomics, but also of social content. The result is a project of inexhaustible strength, that does not wear out after fifty years. The theme of modularity is central, and is already expressed by the name chosen for this sofa system: just as the large boulders that made up the imposing Roman walls, the seating elements come together in the design in a theoretically infinite process. This way, the sofa lends itself to small but also very large environments, without ever losing its stylistic aspect. Tacchini rediscovers this precious project and reissues it, respecting the original design by highlighting the vocation to comfort.
