NEST is a inflatable product designed by Ivan Zhang and Jeho Yoon. By controlling the internal rope structure, the NEST has two shapes and functions: boat and air mattress. The NEST has transparent surface like a ghost glass fish. The inside of NEST is connected by red ropes with 17 spring-hooks. It allows NEST to change internal structure by using it. Due to material, transparent skin, people can easily hook and unhook from outside. When spring-hooks are all hooked, NEST can be used as a comfortable air mattress. Furthermore, internal rope structure can transform from an air mattress into a boat when it is all unhooked.
