Carlos Mello is the founder and head designer of MainGUILTY, a Portuguese design studio that sits at the intersection of product design and art. With a background deeply rooted in industrial craftsmanship, Mello focuses on transforming raw materials—particularly cork, wood, and metal—into functional collectibles. His creative process, often driven by his "UnderPressure" methodology, prioritizes experimental textures and organic forms. He frequently utilizes upcycling techniques to repurpose industrial byproducts, ensuring that his furniture and sculptural pieces maintain a distinct, tactile quality suitable for curated interiors.
Mello’s work has recently gained visibility through significant international and public projects. He was selected to represent Portuguese design at Expo 2025 Osaka with his "Wave of Connections" installation, a project emphasizing sustainable material use and cultural heritage. His portfolio also includes public sculpture, such as the commemorative piece commissioned for AEMinho in Ponte de Lima. An active participant in the European design circuit, Mello has exhibited at major trade shows like Decorex London and was recently recognized with the "Entrepreneurial Generation" award at the Mobis Gala.

Vienna Lounge Armchair, in natural Beech and straw; Acid Green Upholstered Seat
By Emmanuel Gallina
Located in Milan, Lombardy
Vienna longue A living room armchair in wood and straw, that recalls the exclusive club atmosphere but in a contemporary key. Vienna is an extraordinarily comfortable and elegant lounge armchair designed by Emmanuel Gallina who loves to quote Brancusi when saying that “simplicity is complexity resolved”. Inspired by Vienna at the end of the 19th century, then up to the 1950s by Marcel Gascoin, through the visions of the American E.J. Brussel. A tribute to Alfred Sloan’s American pragmatism joined to European styling and, in this particular case, to the renowned Italian talent constantly aiming to harmonize beauty and functionality. In solid beech and straw, Vienna is a perfect combination between digital machines and handcraft. The structure is in solid beech. The back and sides in hand-braided Vienna straw fixed in a milling. Cushions in polyurethane foam in different densities. Removable lining in different fabric categories: cotton, felt, linen, eco-leather, wool, velvet or can be coated with C.O.M. fabric. Optional 2nd cushion available. Finishing is in natural beech or beech painted walnut Canaletto. In the Vienna collection...
