I ordered this headboard twice.  Once as an original order and once as a replacement order.  The headboard had the same problem both times.  
The legs do not line up properly with the headboard. Either way you attach the legs they do not make it a full size headboard.  One way is too long and the other way is too short.  
I was really disappointed because it’s hard to find a full size headboard and even harder to find a full size gray one. 
They need to look at quality control better. 
Maybe the other colors are better.
