Porcupine, a collaboration between New York based architect Eduardo Benamor Duarte and Caterina Tiazzoldi, is a chair designed explicitly for hotel lobbies, restaurants, airports and other waiting areas.
The chair is parametrically generated from a logic inspired by the fractal growth of a shell and different versions of it can be produced to precisely fit a room.
The whole thing is surfaced in felt without any crossbracing. The felt, however, is reinforced from the inside with fiberglass.
The prototypical version of the chair was designed for the reception space of the Altis Hotel in Lisbon.
