Beautiful headboard. Difficult to attach to existing bedframe. We had to drill holes to the headboard to attach it. If you have an older metal bedframe, expect some challenges.  The two recommended pieces weren’t necessary and so now I’m stuck with them. Thank goddess I had a helper who could turn a wrench to fix the problem 

It appears the headboards are designed to fit easily with Wayfair bedframes.  I don’t think the are universal, I don’t know for sure tho.
