So far it has went great with one exception. Very comfortable, feels like I'm being hugged almost since the arms do not have an opening like most chairs of this type. The lumbar feels good and is comfortabl leaning back as well. I dont use the lift feature, so i cant comment on it... mine wont ever go out since it will never get used. Only issue was the arm would not attach to the back of the chair, the bolts provided did not seem to match the thread on the left side. I could screw the bolt in only for it to stop at a point and spin like it is stripped. I put one from my old chair in which looks identical besides the color... went right in and tightened all the way. Assembly was easy besides the bolt issue, maybe about 30min to get it together including finding another bolt.
