The first box had bent brackets so I couldn't even get the shelves on straight. Some of the connecting pieces did have threads so there was no getting this together anyway. I put in for replacement parts and got a second shelf rather quickly. It had other issues, I was hoping between the two I would have the pieces I needed to make a plant stand. That did not work. Also I keep getting e-mails from wayfair that my replacement parts have been delayed despite having received an entire second shelf, even though it can't be assembled either. I strongly recommend picking something else.
