The frame bent after 2 days of use.... I am not sure why there are no poles at the to and end of the bed. There is one pole in the middle. From a physics perspective there is too much weight and there is nothing for it to be distributed on therefore the un-sturdy metal is bending. This was one of the cheaper frames I saw on the website but still a lot of money for me since I am a nursing student. I am very disappointed with the quality.
