This is an awesome unit! I bought it for some closet storage in my nursery. This was super easy to assemble - I did it by myself Im about 20 minutes. While I havent filled it up yet, it seems sturdy and can be secured to the wall. 
With my original unit, a bar arrived bent. I contacted Wayfair and after some attempts to resend a bar didnt go through (warehouse delays due to covid) they sent a whole new unit and told me to keep the original! I was able to swap out the bent bar and off the original to another family. So great product at a great price, and awesome CS from Wayfair!
