The  middle piece is fabricated wrong. There is no reinforcement, making the drawers sag in the middle. The holes on the bottom of the rail should be at the top in order to give the drawer support. Also the instructions were very complicated. Took my boyfriend and I 2.5 hours, and 2 bottles of wine!!! Requested a replacement part, not sure if its simply a mistake on their part or if they are making them all this way. But judging from the previous reviews, everyone is having issues with the drawers. A little disappointed as I don't have a working desk after paying that amount. Hoping that the replacement part will fix the issue or I will request a refund.
