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.

Big Sur Sofa by MICHAEL HILAL
By Michael Hilal
Located in Antwerpen, BE
The Big Sur sofa by MICHAEL HILAL, which he describes “a love letter to California”. The varied topography of Hilal’s home state from mountains to rugged shoreline is the starting point for Big Sur’s shifting interplay of organic shapes. Configurations engage and form spaces for hanging out, catnapping, toasting cocktails or telling secrets. Conceived of as a room’s center-of-gravity, rather than a wallflower, the sofa transforms into a natural gathering place. The ease of California living, a signature concept in Hilal’s work, is reflected in the casual configurations and reconfigurations. The Collection includes two sofa configurations: BIG SUR 1.1 – A modern, sculptural take on a tête-à-tête, this sofa floats away from the wall, offering all sides for lounging and conversation. The single main component is doubled up and features two satellite stools. BIG SUR 1.2 – A 1970s conversation pit...
