When I received the box I could tell it had been open and returned.  After opening it I knew for sure because the hardware was stapled back together after being open.  I should have just taped it back up and sent it back then BUT I needed it now.  
Some of the locking parts were missing and do not work properly.  
It is fairly easy to put together you just need to pay attention. BUT… When I tried to put in one of the screw in a pre-drill hole the wood started separating.  I was using a screw driver as directive and I’m a grandmother so it wasn’t something I was doing wrong.
After I got it all together I realize a coupe of the bars were bent.
It will work until I can replace it..  very disappointed..
