Love this hallway tree! I assembled it by myself and wish i had a second person, but if you want a challenge uou can do it one person. A lot of people complain that the doors don't stay shut, I found that this was true. But I have the solution! Untighten the wood screws that fasten the doors to the unit just a little bit and the door will function perfectly. :) I had to post this to help others out. It was a simple fix and maybe the instructions should state this. Also I attached the top portion to the lower portion on its side and attempted to lift the unit afterwards. The top unit broke away from the bottom in the process. Assemble the top to the bottom with the units upright! I used some gorilla wood glue to bind the two units together. It is still a very sturdy unit and it is so beautiful!  It's also nice to have a clutter free entryway!  Also it is all wood! Do heavy and gorgeous!
