This is the most comfortable office chair I have ever sat in. I put in between 45-50 hours a week for the last 3 years in one and never had one complaint.
I honestly didn't even know how comfortable the chair was until recently when I accepted a new position. Five weeks now in three different chairs (trying to find one at least as remotely as comfortable as the Mobius 4700) and my back is a useless mess.
The Mobius is a wolf in sheep's clothing. It is not overly padded, so the iniital impression isn't that it's the most comfortable chair. In fact, the initial impression the chair makes is that of a stark, vlaue chair with stiff padding. The beauty of the chair is that every stark feature works perfectly. That slightly stiff padding gives just enough to make a six hour stint in the chair completely unnoticeable.
Better yet, the inverse-synchro tilt and zero-lift front is God's gift tyo office workers, no kidding.
Before you spend your money on any other chair, but this one...you won't regret it.
