Landed a nice deal on this during Cyber Monday and haven't looked back since. This is actually better than the $300 chairs we have at work.
I tend to be picky about being able to adjust things and this chair has it all, height, lumbar, arms, tilt. Rumor has it there's even a portal ice cream attached inside, though I've had difficulty locating this particular feature.
Very comfortable back great for everything from 4hr computer sessions to kicking back, propping my feet up, and cracking a book.
While I might think twice about paying full price for it, anything sub $150 makes this chair quite a deal in comparison to it's partially-adjustable competitors in the same price range.
If you are able to locate the ice cream machine, please notify me immediately, it is very important.
