"More lounge chairs at conference and lecture halls please"! For many people lounge chairs offer supreme sitting comfort. Unfortunately they are often bulky and heavy rendering them inconvenient for many applications. The design focus for chair.two was to combine the convenience of stackability, the durability and ruggedness of a cushions-less design, and the comfort of a reclined lounge chair. The intended fabrication material is a compound of a thin aluminum shell and a structure-reinforcing foam core.
