A project conceived by mixing bases of architecture to eco-friendly design. A chair made entirely of cardboard created by young (just nineteen) and creative American designer John Mars. A main strong and durable structure, assembled without glue or any other type of attachment, held together simply by the position and friction caused by the components, capable of standing, amazingly, about 300 pounds of weighs. A seat consisting of a network of equilateral triangular elements, forming a section of a geodesic dome covered with various geometric shapes, basically, three identical modules consisting of a single layer of cardboard, cut, folded and combined with each other depending on their function (supporting elements, connectors or pillows), able to offer different possibilities of reorganization and configuration, and a high comfort level.
