Pins pulled out of pressboard  when standing it up after assembling causing unit to collapse.  Used wood screws and a drill to reattach everything. Woke the next morning to find  the smell of the pressboard (formaldehyde) permeating the entire room.  Its intended use was to store yarn and now I find I have to get rid of much of my yarn due to the odor. I would return it, but it is too heavy and I dont have the energy to take it all apart. So I am writing this off as a loss and putting it curbside.
