Works well.  Is very sturdy.  We put a new mattress on it, one of those box mattresses,  that inflate after you unwrap it.  No box spring.  It is very comfortable and sturdy.  My little boy loves it.   Sorry about the pics,  we need new pillows and blankets now to go with it.  We have had no problems with it.   The trundle underneath is fine also for extra people.  It’s simple and doesn’t lift up or anything but it’s also goood quality.
