Custom Desk Unit (A1)
Made by USM Haller
Designed by Fritz Haller
Conceived in the 1960s by Swiss architect Fritz Haller and product designer Paul Schärer, the USM Haller system began as a structural solution for the USM factory in Münsingen, Switzerland. What emerged was a modular furniture architecture grounded in industrial precision, one whose chrome-plated steel ball-and-tube connector has since become one of the most recognized structural gestures in twentieth-century design.
The Custom Desk Unit A1 distills that philosophy into a focused workspace. An integrated work surface sits above a 14-inch storage compartment concealed by a lockable drop-down door, keeping the exterior calm and the contents close. The proportions are compact without feeling constrained, a balance that has defined the Haller system across six decades of production.

Frequently Asked Questions
Who designed the USM Haller system?
The USM Haller system was designed by Swiss architect Fritz Haller and product designer Paul Schärer in the 1960s, originally as a structural and furniture solution for the USM factory in Münsingen, Switzerland. The collaboration between an architect and an industrial designer produced a system that bridges engineering logic and formal elegance.
What is the USM Haller ball-and-tube connector?
The ball-and-tube connector is the defining structural element of the USM Haller system. A precision-engineered chrome-plated steel sphere accepts tubular steel members at multiple angles, allowing modules to be assembled and reconfigured in three dimensions without visible fasteners. It has been recognized as one of the canonical details of late twentieth-century industrial design.
Can the USM Haller Desk Unit A1 be reconfigured or expanded later?
Yes. The USM Haller system is modular by design, meaning individual units can be added to, rearranged, or combined with other Haller components over time. This adaptability is one of the core principles Haller and Schärer built into the system from its inception.
What surface color options are available for the Desk Unit A1?
The Custom Desk Unit A1 is available in 7 standard surface colors. USM's color palette has been carefully maintained over the decades, ranging from neutral whites and grays to deeper tones, allowing the unit to integrate with a wide range of interior environments.
Is the USM Haller system considered a design collectible?
The USM Haller system holds a significant place in design history and is included in the permanent collections of several major design museums. Its combination of structural ingenuity, material consistency, and configurability has kept it in continuous production since the 1960s, a rare distinction among twentieth-century furniture systems.
