We have a queen headboard and only the King headboard was available (fits both sizes), however it is much wider than our queen frame and therefore doesn't screw into it and remains semi loose against the wall.  Luckily it doesn't move around and seems stable. Has two lamps underneath which is nice, but one bulb came broken. Decently easy to assemble, might need power drill for help.

Pros: Good decorative piece for bed with lighting
Cons: Doesn't fit queen bed as well as king
