Design Details

The USM Haller System
The USM Haller modular system was born from a collaboration between Swiss architect Fritz Haller and USM founder Paul Schaerer. Tasked with designing a new factory building for USM in Münsingen, Switzerland, they developed a flexible construction system based on a modular grid of steel tubes and patented ball connectors. The system proved so successful that it was adapted for furniture—and the USM Haller collection was born.

Key to the system’s enduring appeal is its adaptability. The modular components can be reconfigured, expanded, or reduced to suit changing needs—making each piece a lasting investment that evolves with its owner.

3×3 Configuration
Each unit features a 3×3 grid configuration—three compartments across by three compartments high. This versatile format is ideal for:

• Book storage — perfect for displaying or organizing books of various sizes

• Display shelving — showcase collectibles, art objects, or personal treasures

• Room division — creates visual separation in open-concept spaces

• Modular wall systems — pair multiples for expansive storage solutions

Set of Two
This listing includes two identical 3×3 units, offering exceptional value and flexibility:

• Place side by side — creates a 6×3 storage wall with seamless visual continuity

• Stack vertically — transforms into a taller 3×6 configuration

• Position separately — use in different rooms or areas as needed

Materials & Construction
The USM Haller system is renowned for its exceptional build quality:

• Powder-coated steel panels — custom-made to USM’s exacting specifications, offering a durable, scratch-resistant finish that maintains its appearance for decades

• Chrome-plated steel tubes — signature tubular frame that forms the structural grid, polished to a brilliant, corrosion-resistant finish

• Patented ball connectors — the iconic chrome spheres that lock the modular grid together with precision-engineered strength

Why This Piece Matters

Fritz Haller (1924–2012) was a Swiss architect and designer whose work focused on flexible, modular systems. Paul Schaerer (1910–1988) was the managing director of USM, a family-owned metalworking company founded in 1885. Together, they created a design language that has become synonymous with Swiss precision, modernist restraint, and enduring quality.

The USM Haller system has achieved iconic status for several reasons:

• Timeless Aesthetic — the clean lines, geometric precision, and restrained palette transcend trends

• Modular Flexibility — designed to be reconfigured, expanded, or reduced, ensuring relevance across changing needs and spaces

• Uncompromising Durability — built from high-quality materials with Swiss manufacturing standards; USM Haller furniture is often passed down through generations

• Cultural Significance — represented in museum collections including the Museum of Modern Art (MoMA) in New York and the Vitra Design Museum

This set of two 3×3 units offers exceptional versatility—whether placed side by side to create a substantial storage wall or used separately to address multiple storage needs throughout the home.

Authenticity & Condition

These USM Haller shelves are presented in excellent condition. The powder-coated steel panels show minimal signs of use, the chrome tubes retain their brilliant luster, and the patented ball connectors are fully intact.
