I was surprised about the low quality of some of the pieces but it fit my space requirements.  Overall the panels are heavy and sturdy but I did not like two things. The back panel is basically a piece of thin cardboard which is not unusual for the price point or this type of furniture. But it felt thinner than it should be compared to all the other parts.  Also it had a creasefold in the middle which was a problem for me because even though I tried to nail it down perfectly flat, it did not and I ended up having to nail it in the middle on the shelves which was challenging and not part of the instructions.  The second issue was the white material that covered the MDF.  When I peeled off the sticker labeling the parts for assembly, some of the white part peeled off with the sticker.  Fortunately, it was on the shelf where it could not be seen but still not  happy about it.  If you don’t have to buy this because of space limitations, I would pick something else.
