The Pipe Chair has an aluminum structure and an option of an aluminum seat and back with holes for outdoor use or high-pressure resinated plywood for indoors or light outdoor use. There's an armchair and a side chair version. The tooling for the chair is remarkable, with a variety of state-of-the-art bending machines controlling the tubes' 3-D profiles. It's beautifully made and probably one of the strongest chairs ever built as I chose a large-diameter tube and the structure (especially the armchair) is very rigid. It stacks like a French café chair on the X under the seat, allowing four or five in a stack before it gets too high.

The Pipe chair is also available with arms. It features an aluminum tube painted in polyester powder. Seat and back in punched aluminum plate painted in polyester powder. Suitable for outdoor use.
