It was fairly easy to put together.  I didn’t find the instructions until the very end when I discovered the box of parts and instructions zip tied to the bottom of the base.  The right side panel did not have the controller hook up hanging outside of the cover which was frustrating because I thought I was going to have to tear open the covering to get to it until I realized our old chair we were replacing had the same connection on the old up and down remote so problem solved.  My 85 yo mother is a princess and I was skeptical we would be able to purchase a chair on line for less than 1,500 which she would be satisfied with. But she does seem to find it comfortable.  She lives in her chair and this was a definite improvement from her previous chair.
