Edit: turns out, the screws are all pre-installed and I am an idiot. In my defense, the paperwork only mentions it in a warning on the back of the safety precautions paper, not in the actual instruction manual. I have now edited my review to 5 stars as the chair is very nice and comfortable and I feel bad as the support person was nice and replied the next day. Unless something goes wrong with the chair in the near-future, this review will stay that way.
