So easy to put together. I did it by myself (5’4” female). After reading another reviewer’s comments, I added an additional support beam along the center. (Sistered a 2x4 along the center support). I will update as we use it if there are any issues. 

My only concern is the back panel seems a little weak, so either add support to that or make sure you install this bed against a wall. 

One tip
On the trundle. Screw the cross beams (bed slats) along one side first. Then pull the bed sides together to screw in the other side. I didn’t do this so I have gaps. See photos.
