SEI is a collection designed by Marc Sadler, conceived around the concept of six millimetres—the thickness of countertops, side panels, shelves, and accessories. Panels as sharp as blades, an effect only Italian design can achieve. The project explores the dialogue between materials and colors—wood, marble, steel, and laminate—with a clear goal: to create a simple yet functional system, enriched by high-quality materials, refined interiors, and an expressive use of color. All of this is made possible by artisanal tradition, attention to detail, and technological innovation.
