I was so disappointed that these headboards arrived with deep cut grooves for side rails.  I was just attaching these to twin bed frames and do not have the rails that must have been made for this headboard.  The grooves are very noticeable once the headboard is attached to the bed frame.  Wayfair should have pictured the headboard as made for side rails.  I am going to have to fill them in with wood filter.  Otherwise the product would have been fine.
