USM Sideboards

USM's sideboard collection is built on the same ball-joint frame system that's defined the brand since 1965 — genuinely modular construction, meaning a sideboard configured today can be reconfigured, expanded, or repaneled decades from now using the same connector system, rather than replaced as needs change.

Alteriors carries USM's sideboards as an authorized dealer, built to order in the exact width, height, depth, and color combination your space calls for. Our team works with you to finalize dimensions and panel colors before manufacturing, then confirms lead time for your specific build — this isn't off-the-shelf furniture, so planning ahead matters.

Select USM sideboard configurations are on display in our Toronto showroom, worth seeing in person to appreciate the precision engineering behind the ball-joint system. We ship USM sideboards across Canada for residential and commercial storage.
