It took us two days to put this together, might have been able to do 1.5 days if not for needed breaks. This is at least a 2 person job, don't try it yourself! Instructions are not always clear and take some time to understand. We did have one stripped screw in metal and one screw stripped the wood. Solved the latter by using our own, longer screw as it was a critical piece. 

I will add that the mattress does seem to need a strap at the foot for when it's upright as it's very hard for me (5'3", 120 lb) to open the door as the mattress seems to lean forward and not against the door. That will hopefully help with the issue. There is a hole in the metal frame to allow this attachment of a strap via a bolt.

Some of the materials are the cheaper particle board and not the stronger one or even MDF. Thankfully, the bed cabinet is slightly better quality particle board than the bookcase. The finished look is great. Clean and modern. Overall, pleased with it so far. Testing it out soon.
