I am really disappointed with this purchase. I have bought several items lately to create a work at home space, but this was as it it came from another company. I found the instructions very vague, and in several areas I had to undo steps because they prevent access to another step. The pieces were so snug, they would not clear some of the screw heads to move the side arms, causing damage. Though unseen, it also prevented the arms from locking in place. So I ended up replacing the screws provided with flat heads from my tool box. Its sturdy, and cute when finally together but smaller than I expected. Just overall NOT happy.
