It took a while for the weather to cool down so we could attempt to put this together in the garage. It took a phone call to figure out how to get started. Two pieces are put in the same box and they really should be separate. I think pieces 1 and 2. Very similar but one has a definite foot on the bottom. Once we figured it out we got going rather quickly.The cross piece (5) doesn't always fit tight. And our last cross piece was bent on the end so wouldn't fit. But the shelving unit is large and I may use to for canned goods in my garage. [This review was collected as part of a promotion.]
