USM

USM Haller is the Swiss modular furniture system recognizable by its chrome ball-joint frame and interchangeable colored steel panels — a design classic since 1965 that is genuinely, structurally modular, not just marketed that way. A USM piece built today uses the same connector system as one built decades ago, meaning a sideboard or credenza can be reconfigured, expanded, or repaneled as your space or storage needs change, rather than replaced.

Alteriors carries USM's sideboard, credenza, and shelving configurations for Canadian homes and offices, built to order in the exact width, height, depth, and color combination your space calls for. As an authorized USM dealer, every piece is genuine USM manufacturing — precision-engineered in Switzerland, not a modular-storage lookalike assembled from generic components.

Because USM pieces are configured before manufacturing, our team works with you to finalize dimensions and panel colors, then confirms lead time for your specific build — this isn't off-the-shelf furniture, so planning ahead matters. If you're weighing USM against a cheaper modular storage system, the ball-joint connector system and repairability over decades are the real differentiators. Select USM configurations are on display in our Toronto showroom, and we ship across Canada.
