Bought this chair in black for use in a home office. 

Assembly out of the box was a cinch-- instructions were included but not necessary. I had it together in less than ten minutes (and that was after a couple of cocktails!)

The leather is bonded but seems to be of a decent quality. Sitting in the chair was reasonably comfortable, and the hydraulic seat lift works just as expected. 

I deducted one star from my rating because the shiny chrome finish was flaking off in one place that was semi-hidden under the seating area. It was a smallish area (about the size of a ketchup packet), and certainly not enough to warrant sending the chair back. A quick hit with an abrasive pad and some clear polish should prevent any further damage.
