I like the way this frame was designed. Knowing I had to watch corners on a tight stairway to the second floor destination for this frame, I was pleasantly surprised by the way it was folded in half. It is fascinating that once you unfold it and put the mattress on top, you would never suspect that it was anything other than a quality bed frame. Feels like a solid piece, yet is lightweight enough to move the bed when I want to clean under and around it!
