The product launch of USM Haller E at Salone del Mobile in Milan was staged by the renowned Swiss design studio atelier oï with an attention-grabbing trade fair booth: in an imposing cityscape, the highly stacked furniture modules converged into an urban world. The warm light from the illuminated windows offered views inside imaginary living spaces with suggested scenarios. Visitors were able to discover many new aspects of the USM Metropolis under delicate paper clouds hanging above them in the night sky. The task of the NUSSLI Group was the implementation of the complete booth.
