This office chair is the Cadillac of all office chairs, I have ever had.  It was relatively easy to assemble, but at one point it was good to have another person to help attach the back to the seat.  Otherwise, the instructions and the assembly were easy.  Overall, the chair, from the seat to the feet, is great solid construction.  It is very comfy and supportive.  My only negative is the size of the arms.  Even though, they are appreciated for the support and comfort, they are little too big for my small home office space. But the easy to use lift and tilt, the padded leather and the seat size, make up for this small personal issue for me.
