This conversion kit was very easy to put together.  I was able to do it by myself in about 30 minutes.  At first I thought there were nails/bolts missing, but then realized that the instructions don't necessarily match the parts that were provided.  In fact, I received many extra that I didn't need, but at least I got what I did need.  Only four slats are provided, which I tried to space out evenly, but once the mattress was placed on top, you could feel that the bed is not as stable as it probably should be.  Our bed has slats, which are approx. 2 in apart, but with only four slats for this bed, they're about a foot apart. The delivery was fast and came packaged well.
