Very nice construction very sturdy better than the box store bunk beds top bunk can defiantly hold the weight I climb up there and I weigh 270 to lay with my 5 year old when she wants me to sing lullaby only down side is that you have to screw the step spurt directly to the bed damaging it wish there was a pre drilled hole or something that would slide around the bed that I could screw to to remove if I have to change sides or split the bed if I get a bigger place
