INSPIRED BY MODERNISM

Inspired by the clear, lightweight elegance of Modernist architecture—from modest social housing to refined private villas—the concept embraces geometric clarity and a ‘less but better’ attitude. It explores proportion, modularity, and precise detailing to create a versatile, human-centered seating system.

The Collection covers a wide range — from armchairs and compact sofas for homes, even in small sizes - to modular configurations for offices, hospitality lounges, and public spaces, including high-back variants for enhanced privacy - always with coordinated side table for easy mix and match.

CHOOSE EVERY DETAIL

Spectrum is a system, not a statement. Like people, it carries multiple identities - quiet or bold, classic or edgy - depending on what you need it to be. Easy to configure, it can be dressed up or down to fit any space with style and comfort.

A flexible arrangement of expressive elements—seat, backrest, cushions—built on a base like the perfect white shirt – lightweight, timeless – and can be further enriched three base options and three armrest types.

COLOR AND SPACE

We approached the modular Spectrum System as a way to choreograph interactions. It’s not about static seating, but about creating flexible landscapes that support the flow of social life.

Designed for those seeking calm within the collective, Spectrum Highback creates a place a more focused state of mind. The highback variation builds on the fluid design of the Spectrum system creating islands of acoustic and visual privacy.
