The designer cleverly adopted a three-layered structure to shape the sofa chair into a three-sided enclosed wrapping shape. The shape comes from the environmentally friendly posture from behind. Through the use of continuous arcs and curves, the designer successfully gave this chair an irresistible roundness and intimacy. These curves are not just decorations, they contain a natural vitality, adding a beautiful visual sense and strong centripetal force to the sofa, making you feel a comfortable experience of being surrounded by warmth every time you sit down.
