This is a nice, solid, well-made headboard.  We used it on our California King metal box frame.  We had to  rearrange the left/right legs and line them up about an inch outside of the headboard, but we were able to attach it this way without drilling more holes.  With the box spring and thick mattress in place, you can't even see the legs sticking out beyond the headboard.  The headboard makes the bed and bedroom look much nicer.

Pros: solid wood, nice finish
Cons: didn't really fit our metal frame at stated size
