Not as advertised.  Specs on chair indicate Adjustable Lumbar Support and Massage.  This chair does not have either one.  You can not adjust the chair back angle as it is attached to the seat.  You can adjust the entire chair angle slightly, but that also tilts the seat angle.  The box arrived with wheel assembly broken through box.  Does not appear to have any damage to the actual chair.  The seat section and the chair back section are held together by the chair arms.  4 screws for each arm.  (2 into seat and 2 into chair back)  This was difficult to line up the screws with the holes in each section.
