I want to start by saying that the frame of the bed was relatively easy to put together, despite HORRIBLE instructions. The worst piece of the assembly were the rails for the mattress. The tension of the cord that you have to slide rails through is so huge that when you secure one side, the other one pops right out! So frustrating. So I couldn’t do it and eventually my father had to make small cuts in the rails to lessen the tension.. 
I gave the bed three stars because it looks nice.. put the process was simply painful..
