Mammamia Raw Chair
The Mammamia Raw chair by Marcello Ziliani for Opinion Ciatti gives the collection’s curved profile an exposed natural-aluminum finish.
A clear matte protective coating preserves the deliberately industrial surface, with variations making each piece distinct. Transparent foot caps complete the restrained outline of this non-stackable chair for indoor or outdoor seating.
Every detail, considered.
