The final product is great except for a few minor issues. There are a lot of pieces to assemble. It took about 3.5 hours to put it together. A few of the pieces were cracked but nothing to stop us from building it. The slats used to hold up the mattresses are spaced very wide apart. If using a foam mattress I would suggest using plywood on top of the slats. Foam Mattress will fall through, esp at ends.  My kids are light enough that we weren’t in a big rush to get the plywood (much safer with it). If using a coil mattress, which is suggested by manufacturer, it should be fine.
