First, I made a template of this chair in wood in 2D. So, I could putted the template on the corrugated paper to cut it out with a milling cutter. One of this paper is 0,5 cm thick. So I had to cut many of them to glue them together. It is very stable and on the seat I glued some cutted cork (corkroll) on it. Under the seat, there is space for everything you like, such as books or cd's or maybe a bed for your cat.
