Must be called a dang chair...

I would like to see what ree could come up with. I bet it wouldn't be nearly as good as this.

maybe a counterweight and/or a spring mechanism to finish it off.

It looks more like a device to summon Lady Gaga.

You might want to sand it, last time i worked with a big wire spool i got a chunk of wood stuck into my hand.
