David thinks he spent about 200 hours making the seat. It started as a 1 1/2" thick stripped poplar block in a roughly curved shape. He first worked it with a rasp and angle grinder into a closer approximation of a seat. Then, he sanded and sanded and sanded and sanded some more to reveal its final curves, before freehand-cutting the profile. The frame, on the other hand, was assembled in one marathon overnight build the day before the deadline, while the polyurethane seat finish dried. One lone screw holds the two pieces together. You’d be right if you thought the seat’s contrasting strips looked like racing stripes. David designed it that way.
