Furniture Design Pinch Chair by Chung Ping-Lun The Pinch Chair is a unibody, stackable, plastic chair that reimagines traditional designs with a fresh aesthetic more suited to contemporary architecture and landscapes. Designed with a unibody logic, the plastic sheet transforms into a complete chair with simple pinching and pulling moves. Its seamless, cohesive appearance creates an intuitive and dynamic visual image. The design allows for stacking during storage and stable placement on a dining table when flipped upside down, which is convenient for restaurant staff to clean the floor when closing.
