It is a solid piece. The issue I have is I ordered a queen size yet it was too small! It moves around of you don't fill in the gaps. I don't know why it says queen of its actyally smaller than than. Very disappointed. Just like all other reviewers said, they're right. It's too small, I had to put metal clamps in the middle to attach it to the bed and had to put pieces of wood on either side of the bunkie board to make sure it would stay in place.
