Only slept on it a few times so far, but seems sturdy.  I only removed a star because it was a bit of a project to put together, especially alone.  Some people may not be able to put it together solo.  It is a little heavy and some pieces are difficult to put together without assistance.  By myself, it took over 2 hours to put together.

One small issue, as I should have assumed is, mattress slides somewhat on the metal bars.  I need to buy some stuff to keep it in place very soon.
