This is what happens when you put me in a room with 2 2x4's and a saw.
I saw the Steltman Chair at SLAM a few months... err.. make that probably years ago and thought, "I love that!" Anyway, band practice got canceled at the last minute so I put on some gloves and started sawing. I didn't have any drawings and I couldn't remember its name so this is all from memory.
I found a picture of the original online today. I'm surprised at how close I got.
By the way, the original artist's name is Garrit Thomas Rietveld. His chair is badarse:

Apparently, I hacked together the left-handed version.
By the way, this chair is for saleā¦ It isn't very sturdy so I'll take \$25 for it.
