This is a third outdoor chair that I built using scraps of pressure treated SYP decking that were left over from a deck skirting project last year. The first two chairs were replicas of Hans Wegner's GE-375, and this one is a replica of a Ib Kofod-Larsen chair. I could find only two websites with photos of this chair (here's one), which does make me question its attribution to Kofod-Larsen. Regardless, I liked the lines of the chair, and thought that the design would suit the stack of narrow scraps I had available.
The original chair supported the seat and back cushions with a set of parallel Pirelli webbing straps. For this outdoor chair, I opted for laced paracord. The full build is chronicled here, but below are a few photos of the chair coming together.
The biggest challenge was getting the lengths, positions, and angles right for the side assemblies to come together as designed. There were no right angles at any of the 3 butt joints and 1 miter joint to serve as a reference. While the angles all work out on the drawings, once the pieces were cut by a flawed human, they required some fine-tuning to get everything to fit together. Once I had a matching set of side assemblies, the remainder of the build went smoothly. All around, it was a satisfying project.
