This is very difficult to assemble unless you can read Chinese. All the items look slightly similar so you really have to concentrate what pole is what. I consider myself pretty good at assembling but this was difficult, and I had a cold so my brain was foggy too. LOL Finally got it together. It is NOT super sturdy so I will only be using it for my seed starters in the spring. My grow lights fit perfectly underneath the shelves too so that was good. Overall - you get what you pay for. :-)
