Spectrum is a modular sofa system designed to adapt with ease. Elevated on slim legs and softened by tailored upholstery, it brings a sense of visual lightness alongside ergonomic comfort. Its seat, backrest, and cushions are shaped by precise tailoring details, complemented by three leg options and three armrest styles that can be freely combined to suit any project. Elegant from every angle, Spectrum works as a standalone piece or as a system, shaping relaxed, open environments for work, waiting, or conversation.
Altherr Désile Park (ADP) is a Barcelona-based design studio known for its holistic approach to product design, art direction and creative strategy.

For Prostoria, Altherr Désile Park has developed several key collections, including Spectrum, Spectrum HB, and Spectrum System. Through these projects, the studio explored the relationship between comfort, architectural clarity and spatial flexibility, creating seating systems that adapt naturally to both residential and contract environments.
