It is named after the IX Milan Triennale, where it was first exhibited. This piece was revolutionary because it showcased Zanuso’s early experimentation with industrial materials like foam rubber and elasticated straps—technology originally developed by Pirelli—which moved furniture away from heavy, traditional internal springs toward lighter, more sculptural forms.


Key Details
Design Significance: Debuted at the IX Triennale di Milano, it was one of the first sofas to replace traditional springs with foam rubber (Latex/Pirelli foam) and elas, organic shape.
Structure: It typically features a slender metal frame with distinctive "stiletto" legs, giving it a light, floating appearance despite its comfort.
