Very sturdy! Easy to follow directions. I love that there are stickers that tell you "inside bottom", for example, so that you are placing the railing on the correct side. The hardware that comes with it was well thought out and made to keep from stripping the wood. I'm very satisfied with this crib. The packing it came in was great too. If I had to say there were any issues, I'd say that in the description, it says made in the USA and paint is organic/lead free but the sticker on the crib says made in China with lots of CA. regulation warnings about product being harmful. Love the crib, otherwise.
