That's cool! Does it mean you don't need to stand up when you need to use the toilet during a WoW raid?
EDIT: Ummm... I was just joking about literally sucking ass. And referring to the South Park episode with World of Warcraft. Sorry if it didn't come through as funny.
I have a secret labs chair and use it a lot for working at home. I often sit for more than 14 hours on it, never had any back pain ir felt uncomfortable.
Unfortunately I have one of the older generations and the arm rests are slowly deteriorating and falling apart, otherwise it's pretty good.
