A bit challenging to put together but it is sturdy.  Center rail is good for that.  Isn't overly amazing but  gets the job done.  

My only complaint is that it seems as if it may be just a  tiny bit too tall/off the ground.  Also, the holes at the end that should match up to put a headboard on aren't big enough to fit the screw that goes in the headboard I bought.  I'll make it work obviously.
