Furniture Design Line Chair by HYOJOO_M One reason for the constructing this chair as a line is that it has to be mingled in any space. It is consisted of a very thin wood frame (3cm), and forms the structure of the two single lines. Simplest form is hiding a very complex structure invisibly. So producers who can be produced this structure are very rare. For this reason, this chair has designated by one craftsman / one chair system. This is currently produced by one craftsmen in Denmark and another artisan in South Korea, so the massive production is impossible.
