Assembled pretty easily, and did require a rubber mallet to get things into place. One person can assemble it, but it’s easier with two. It’s very sturdy and I loaded it up with paint, boxes of supplies and other heavy items. I would have given 5 stars except the part that joins the top half to the bottom half (it connects the verticals) is plastic. Given that each shelf is supposed to be capable of holding a couple hundred pounds, I expected this load bearing part to be metal and not plastic.
