I'm "serious" in the sense that this is indeed what I'm planning to do (I haven't gotten the Airtouch table yet as I've only recently come back around to the idea of having a desk at all, but I already have the lounge chair/arm mount combo thing).

I recognize that it's kind of pretentious (although my previous plan was to make my office into a 1940's detective office, so I'm no stranger to pretension).

Congratulations! I definitely envy you for the LC4. From 1 to 10, how comfortable is it?

It's really really comfortable. Maybe an 8 or 9 (I suppose I'd reserve a 10 for "the womb").

I've always had a hard time figuring out what to do with my arms though, as I either hang them down by my side, or sort of fold them on my lap, so for years, the chair has mostly been "occasional seating".

With the arm mount though, I end up having a really comfortable typing position.
