Well labeled pieces made it easy to make sure everything was there. Make sure to read the instructions before the first step. I put the track on for the file cabinet part didn't read before that to take it apart so you have one part for the drawer and one for the cabinet. Took 3 1/2 hours for me to do alone. Would have been helpful to have help. And when I was putting the file cabinet drawer on, the plastic end cap of the track came off and the little metal piece with all the ball barring came out. I figured out how to put it back together and it looks nice and works well. So can be put together alone but easier with help.
