If more than one review is saying something, 9X out of 10 it is true. Let me start saying, I have assembled my fair share of furniture, so I have a bit of experience in this area. I knew right away that this unit was poorly designed. I could touch the side and it would make a wave motion. Totally unstable. When I called the Manufacturer, I expressed my concerns. The woman I spoke with claims that anyone who did not have a stable unit did not add the cardboard paper back to the unit, because that it what stabilizes it. I knew if I added Part J with all those nails, I would have a hard time disassembling it to return it without ripping the cardboard back, so I did not go there. No paper back will stabilize it. She was so defensive, I knew it was in my best interest to return. Let me save you $23 in a return fee and some headache, DO NOT BUY THIS!
