4321-MARKET: BALL-ER explores the unexpected possibilities of the iconic USM Haller ball. For this edition, designers were invited to reinterpret a key component of the USM Modular Furniture, not as part of a conventional furniture structure, but as the starting point for small-scale, creative, and festive objects.

A total of 23 teams and 30 designers embraced the challenge, employing diverse and experimental approaches to transform a familiar structural component into unexpected objects. Ranging from functional everyday pieces to sculptural works, the collection demonstrates how the USM Haller system can inspire creativity well beyond the realm of furniture.
