Looking at picture it does not show that it has to be anchored to wall or it will topple over.  There are two wall anchors, obviously not installed on this picture.  The problem is the bottom is not notched for molding so if you do anchor it leans out at molding.  Allen wrench was terrible, difficult to use and finally after assembling had to use gorilla glue as it is not very sturdy and will fold even when assembled.  Sorry I bought it.
