I was afraid this might be one of those chairs that looks great but isn't the most comfortable but after reading a bunch of reviews decided to give it a shot.  It's really beautiful AND very comfortable.  I have worked two ten hour days at my computer back to back and no complaints, it's wonderful.  I got the darker color for my fiancee and he loves his too.  The "leather" is more of a suede-ish fabric which I actually prefer, since PU leather sometimes starts to crack with age/dryness etc.  I would think this fabric will hold up better over time.  Super happy with these.
