I only have two complaints. First, it was poorly packaged. An arm rest, which was wrapped in bubble wrap, fell out as I managed to get the “box” inside. Second, the arm rests are difficult to get onto the chair. Better instructions would be helpful. I found that mocking them up loosely and tightening them alternatively was helpful. However, as I have been breaking the chair in I think additional tightening will be required. Don’t throw away the Allan key!!!
