SOFA_XXXX was completely handmade, making it difficult to mass produce. However, I prefer to produce practical items for daily life rather than making art.
In order to use this as an object in daily life, we chose to use plastic injection molding. It can be built by simply snapping the pieces together. With only 8 elements many shapes can be made. (e.g. Sofa, Stool, Table and Bench etc...)
