Directions do not tell you to put “E” front bar in a specific direction. Therefore after finally putting together I would have had to redo entire bed to use the safety rail. In end I didn’t want to do that work again and left it without the rail and actually think it is way better without… looks beautiful my daughter LOVES it and I find it safer, one less thing for her to hit her head on. Love this bed! I put it together myself, my friend was there and held it once which helped but isn’t super necessary. If you have second set of hands it helps but I don’t believe it is necessary.
