This is a very solid bed frame! It was fairly easy to put together, with the exception of lining all of the 36 or so  screws up to fit them properly into the holes. Some went in fairly easily, but many required a bit of maneuvering before they went in. 
One other note - if possible, have four people on hand to LIFT the mattress onto the frame. The sticky tape on the slats meant to hold the mattress in place, really does keep the mattress in place! 
All in all this was a good buy at a good price.
