Jig Seat, a simple chair from FLATarchitects based in Amsterdam, the Netherlands, takes particleboard from substrate to stylish. The production of a Jig Seat is simple and inexpensive. All parts are cut from a single flat sheet of 12 mm particleboard, and the pieces fit together puzzle-like without glue, staples, screws or dowels.

The design is an effort to show off particleboard, a product often not appreciated for its aesthetic qualities and typically hidden beneath a decorative layer. “The mix of various 'waste' materials in  particleboard gives Jig Seat's surface a unique and rich quality, says Jos Blom of FLATarchitects. “This effect is intensified by  a transparent coating, which renders depth to the material.”
