Very upset! Almost put together and the top piece wouldn’t lineup because the bottom was warped!the two back screws that attached the top to the middle made the screws not long enough,so was no need to go any further because nothing else would line up.So upset because I was almost done and ready to use .I wish now I had paid the extra to come already put together.bottom peice is clearly warped!!throwing everything off!.I was sent a replacement and it was even worse than the first one!i will never order anything else from here.
