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 co-developed by Swiss architect Fritz Haller and product designer Paul Schärer in the 1960s for USM U. Schärer Söhne in Münsingen, Switzerland. Haller's background in industrial and structural architecture is evident in the ball-and-tube connector that defines the system's geometry.
Can USM Haller furniture be reconfigured over time?
Yes. The modular logic of the USM Haller system is specifically engineered for reconfiguration. Components can be added, removed, or rearranged as spatial or functional needs change, which is one reason the system has remained in continuous production for over five decades.
What surface color options are available for the Desk Unit A1?
The Custom Desk Unit A1 is available in 7 standard USM surface colors. Because it is made to order, color selection is confirmed at the time of specification.
Is the drop-down door on the storage compartment lockable?
Yes. The 14-inch storage compartment on the Desk Unit A1 is secured by a lockable drop-down door, making it appropriate for private or shared workspace environments where document security matters.
How does the USM Haller system compare to other modular office furniture?
USM Haller is distinguished by the precision of its chrome-plated steel ball joint connector and the consistency of its module dimensions, which allow virtually unlimited configuration. The system carries Swiss quality certifications and is produced at USM's original facility in Münsingen, maintaining the manufacturing standards established at its founding.
