Pro Posturefit model promotes better posture
The posturefit add-on provides sacral support that promotes a better upright stance while not reclining, and reduces the need for reclining. This posture is particularly better for computer or desk work. It is important to note that although the posturefit add-on can be removed, it cannot be added to a chair that wasn't built for it.
Pro 12 year warranty that covers everything
Pro Mesh is cool (not hot)
Con Default lumbar pad doesn't provide broad support
The default lumbar pad feels like a bar across your back and does not distribute support evenly. The posture fit add-on that does a better job providing broad support is build into the chair and cannot be added to one without it already.
