hero-compatibility

Klackjoy designs modular furniture built to the USM Haller standard — the same 25mm chrome-plated brass ball connectors, the same tube dimensions, and the same RAL powder-coat palette — so our pieces are physically compatible with genuine USM Haller and can extend an existing unit. Everything is configured in a live 3D tool: choose any size, mix colours across panels, add a wood-panel option, and see your price instantly. Swiss design sensibility, factory-direct pricing (around 60–70% below USM Haller), and a 10-year structural warranty. Shelving, sideboards, lowboards, highboards and office storage — reconfigurable for life, not landfill.
