I am sure this chair would be good, but if you get a bad unit in regards to quality control be prepared to be in a world of discomfort. The unit I received had the holes drilled into the bottom of the seat for the armrests completely uneven on opposite sides, meaning the right sticks out further than the left causing me to lean uncomfortably in the chair. Secondly, my back rest does not hold in place, and will always bottom out to the lowest level. Third, my right armrest is faulty and can be easily pushed around to different settings without much force, simply leaning my elbow on the arm rest will kick it all the way out.
After one day of use, there is a noticeable wobble in the mechanism that holds the base to the lift and is noticeable anytime you lean back in the chair. Lastly, the seat cushion is the worst of any chair I have ever used, it seems supportive at first but after an hour leaves my tailbone in absolute pain.
Took quite a bit of back and forth but ultimately the seller was receptive of the issue and offered to replace any necessary parts.
