USM Haller vs Klackjoy: Which Modular System Is Right for You?

If you're in the market for premium modular furniture, you've likely encountered the iconic USM Haller system. But there's a compelling alternative that's been making waves in the design world: Klackjoy.

In this guide, we'll provide an honest, side-by-side comparison to help you make an informed decision.

The Heritage

USM Haller

The USM Haller system was developed in 1963 by Swiss architect Fritz Haller. It has since become a design icon, found in homes, offices, and even museums worldwide. The distinctive chrome ball-and-tube construction is instantly recognizable.

Klackjoy

Klackjoy emerged as a response to growing demand for USM-compatible furniture at more accessible price points. Built on the exact same 750x350x350mm grid system, Klackjoy components are designed to be physically interchangeable with USM originals.

Materials & Quality

| Feature | USM Haller | Klackjoy | |---------|------------|----------| | Ball Connectors | Chrome-plated brass | Chrome-plated brass | | Tubes | Chrome-plated steel | Chrome-plated steel | | Panels | Powder-coated steel | Powder-coated steel | | Color Options | 14 standard colors | 14 USM-compatible colors | | Warranty | 10 years | 5 years |

Both systems use high-quality materials. The primary difference lies in manufacturing location and brand heritage.

The Price Factor

This is where Klackjoy truly shines. A standard 2x2 USM Haller sideboard can cost upwards of €2,500-3,500. The equivalent Klackjoy configuration typically ranges from €800-1,200 — a savings of 60-70%.

For budget-conscious design enthusiasts, this makes professional-grade modular furniture accessible without compromise on aesthetics.

Compatibility Deep Dive

One of Klackjoy's strongest selling points is 100% dimensional compatibility:

✅ Same 750mm x 350mm panel dimensions
✅ Same 35mm tube diameter
✅ Same ball connector specifications
✅ Can extend existing USM installations
✅ Mix-and-match components seamlessly

This means if you already own USM furniture, you can expand your setup with Klackjoy components — or vice versa.

Who Should Choose What?

Choose USM Haller if:

Brand heritage and resale value matter to you
You need the full 10-year warranty
Budget is not a primary concern

You want the USM aesthetic at a fraction of the price
