The crib is beautiful, with soft colors and designs, sturdy and high-quality construction, very spacious to comfortably accommodate your growing child. To be honest, we do not use the adjustable railing because our baby is already high enough with the mattress, so personally, I don't find it necessary to adjust it up and down every time, so I don't have an opinion on how easy it is to use. I also don't have an opinion on assembly since the store sent someone to assemble both the crib and the matching dresser we purchased. The only somewhat negative thing I can say is that the drawers at the bottom are completely open from the top, so whatever you put in there will need containers, otherwise it will collect dust.
