One Piece Seating

1951
The PK25 designed by Poul Kjaerholm, is one of the first examples of a chair being formed from one plane of metal. This chair was cut and bent to create the structure. The methods of construction help dictate the final form















1966
This bent plywood chair buy Verner Panton, the “S” chair 275/276 is a take off of the Ritfield Zig-Zag chair. Bending one planer surface in the “S” shape creates the form







2006
Marc Newson used abrasive water jet technologies to cut this chair out of solid marble. He calls it “extruded”, even though it is not, this is most interesting because of the manufacturing process used and material, think about it if it was extruded aluminum









2007
The “Get Bent Chair” by Alexandre Bertiaume is made by simplify one cut and four folds. This chair is very minimalist and also produces almost no waste. The seat folds back while the arm and back rests fold up to support the body.













2008
The Carpet lounge by Felipe Zanardi also creates his chair by cutting a planar surface, but he slide the “carpet” up to create the backs. The contrast between the carpet
and ground let the viewer see how it was folded up.






All of these chairs with the expectation of the “Extruded” chair get their form folding a single planar element. The Extrude chair is similar in the way that it is a plane that was extruded in a direction. These chairs are all very true to their form and do not hide any thing. Another way to connect these chairs is that they are all pushed or pulled to create their forms.
