Organic forms are geometric shapes found in nature that resemble the structure of organic molecules. “Expandable” is a new concept introduced by MainGUILTY to create authentic living organism shapes in each environment. The concept aims to use fluid and curved organic shapes to create an atmosphere that evokes nature and life, bringing a sense of harmony and tranquility to the space. The idea is to bring nature indoors, providing a unique and pleasant sensory experience to users.
