I put this shelving unit together on my own while my three littles were running around me. It was so easy because of the clear instructions. I was nervous at first because the plastic clips provided do not wrap completely around the poles, but once the shelves were secure in place, it didn't seem to matter. I used this unit in my pantry closet, and I am now convinced that I need three more in here. I highly recommend this for any storage needs, including pantry, basement, and garage. I just got a membership to a bulk store, so I am very glad this unit is able to hold so much weight.
