This should be a one piece solid unit. Where the pieces connect, they sag and have no strength. We had to use additional reinforcements to hold it up which makes the piece very unattractive.
Instructions are inaccurate, materials are flimsy. Without my ability to piece something together it would not have worked. Be sure your time spent trying to make it work isn't worth purchasing a higher quality product. Good luck if you choose to purchase this item.
