This was a little difficult to assemble because the plastic connectors were really warped and misshapen. I had to force quite a few of the legs in to connect it. Once assembled, I was concerned that it wouldn't be very stable since it rocked a lot. After loading all of the shelfs, it now caves in the middle of some of the rows and looks like it is going to buckle. Each shelf has less than 40 lbs so it is not like I stacked a lot of weight on the shelf. Missed my return deadline so I guess I'm going to have to order something more stable.
