Geometrical EXO Chair by Fetiche Design

We're used to see ordinary chair design with curve design offer the comfortness. Fetiche Design, a team of designers from Brazil, create unique chair design called EXO chair, that means Exoskeleton because this chair aim to protect the internal organs of the body and provide support for the muscles. This concept underlying both designers of Fetiche Design (Armellini and Paulo Biacchi Carolina) in creating a chair for furniture company Schuster. I never try this chair, so I can't say about its geometrical design whether gives comfortness or not.
