Sort of a pain to put together. It took a hammer and a ton of pounding to get the frame to lock into place. It was also incredibly loud since I had to point on metal. I used some of the cardboard between the hammer and metal frame to reduce the noise but it was still jarring. Now that it’s together I also found that the “supports” so not fit into the holes. The selves work without these and are stable but I would not buy this system again.
