Furniture Design Toma Living Sofa by Yuto Yamada This sofa was born from the act of wrapping it in a single piece. It has become a unique sofa with undulations. This project began with the question: could we express the commonplace piece of furniture that is the sofa in a freer form? The idea expanded from the thought that wrapping it in a single piece of fabric, like crepe, might yield an interesting shape, leading us to arrive at this form.
