Italian Modular Sofa by Piero Lissoni for Knoll Avio System with Marble Base

Minimalist Italian modular sofa with verde alpi marble base

Designed by Piero Lissoni for Knoll, this rare configuration of the Avio modular sofa was produced in the 1980s and reflects the elegance of Italian modernism. Upholstered in soft ivory fabric, the floating seats rest on a minimalist steel structure, anchored by a dramatic verde alpi marble platform that doubles as a low table or display surface.

Architectural design with sculptural material contrast

This configuration is part of the iconic Avio system, designed to offer flexible, modular comfort without sacrificing architectural precision. The polished marble slab grounds the form with a sculptural presence, while the modular cushions provide plush functionality. The contrast between stone, steel, and fabric exemplifies Lissoni’s refined approach to minimalist design.

Knoll and Piero Lissoni – timeless Italian-American design partnership

One of Italy’s leading contemporary designers, Piero Lissoni created the Avio system as a celebration of simplicity, proportion, and material sophistication. Produced by Knoll, the system showcases the company’s commitment to innovation, architectural clarity, and high-performance craftsmanship—making this piece both collectible and livable.
