Designed in Switzerland in the 1960s by architect Fritz Haller and engineer Paul Schärer, USM Haller transformed modular furniture into an architectural system. Built from precision-engineered steel tubes, chrome-plated connectors and interchangeable panels, every piece is designed to evolve rather than be replaced. More than furniture, USM represents a philosophy of longevity, adaptability and timeless design—qualities that continue to influence homes, studios, galleries and museums around the world.
