Christopher Chair by Brooklyn NY based Charles Constantine.
Charles e-mailed me some photos of this chair and explains:
The chair is part of the collection “A Family Affair” which includes an indoor chair made from maple, a “mud room” bench and, Christopher, the patio piece. This collection debuted at Model Citizen’s NYC in 2008, and a prototype of the Christopher chair was shown at CTRL ALY Seattle in early 2010.
The design details of the chair are function first. The HDPE that makes up the back rest act like a leaf spring on an automobile, and conform to the user. The gradual slope of the seat pan allow for water to drain down and out the back of the chair. The matte grey finish is offset by small color accents. The welds were intentionally left as is to give the chair a handmade quality. The chair is stackable, and 100% recyclable, as it is made from aluminum, and repurposed HDPE.
