'''But you have to actually build it. You have to work every day. You have to sit in the chair and stay seated. And sleep and come back to the chair. You need to wear out that chair and then buy a new one and then wear out that one.'''
Solid advice from Brent Simmons.
I should also note that I recently got a Haworth Zody to sit my butt in. And if you're thinking of checking one out, make sure to go to a local dealer (and don't buy it online from Sit4Less- you can get it for a lot cheaper locally).
