Very disappointed!!  Received my new Full Size bed frame yesterday. Today I tried to attach the “Full Size” headboard to the frame and the slots on the Headboard don’t align with the slots on the bed frame. It’s about 2 inches off on one side. So instead of having them attached (as they Should Be) I have the Headboard up against the wall and the frame with mattress up against that. Either misprint on your website or poor workmanship.
