Would have been 5 stars....but....First I love the look and material of the headboard....very sleek.  It was purchased to attach to a steel platform king bed and required that we use the adapter since the bedframe was wider than the headboard attachment posts.  We had to scrounge up 4 long bolts since not enough were provided when using the adapter....also the adapter has fewer height adjustment possibilities than if you were making a direct attachment of the headboard to the frame so it ended up being about an inch shorter than the ideal height.  Not the end of the world...and enough to knock it down a star.
