Each tubular cushion is a foam pool noodle, wrapped in black cotton, with a dowel running through the center. The plywood has been drilled to accommodate the dowels and hold the cushions in place. Each piece of plywood is a 1/2" from its twin, making the total breadth of each plywood assembly 2"; since the strips are 2" across as well, each of the eight plywood sides is two inches square in cross-section -- another set of squares.
The joints are cast aluminum, made using the lost styrofoam process. I know most people don't have access to a foundry, and getting custom work cast is expensive. However, the joints could just as easily be made out of wood, hopefully something that provides a nice contrast to the plywood.
This particular project doesn't hew too close to my "readymade" ethos, in that it is not made totally from recycled junk, and I spent some money on it. That being said, the plywood was leftover from another project, the pool noodles were leftover from a party, the fabric came from a thrift store, and the aluminum is recycled. Making a chair out of relatively small pieces means that you can usually make it with scrap.
