George Brin builds furniture out of local, sustainably harvested alderwood and maple that he laminates into plywood with a water based adhesive. It is all very minimal and light; he gets six of his shaker-style chairs out of a single sheet of plywood. Everything in engineered to use as little material as possible. The lamp is made out of popcicle sticks.
George bases all of his dimensioning on the Henry Dreyfuss classic "the Measure of Man and Woman": there are two depressions on his bench for your bum cheeks that are spaced exactly 7.1 inches apart as Henry specified.
A special TORX driver is supplied so that the purchaser can tighten things up over time.
