I purchased this bed for my 9 year old and he loved it! I was able to assemble it in about 2 hours mostly by myself, but I did require his help holding the side panels and footboard I'm place to line them up properly. The lights work perfectly BUT the music I can't seem to figure out. Also, the app does not work. The domain is no longer in service so good luck getting help w that. Kind of disappointed, which is why only 4 stars
