Input: I bought this bed is it convenient disassembling. I received it packaging is very heavy. Three people carry it upstairs. May not be familiar with the process It took me two hours to install it. But it is incomplete. This makes me very disappointed. There are 3 steel bar could not match. In the middle of the rail gap is too big screw to help them links. Sellers can changing the spare parts but more than 100 pounds of packaging can't waste a lot of time for me So if you want to buy. Please consider carefully
