Headboard is solid and even attached only to a metal bed frame (as opposed to much more sturdy full bed side-boards) it has only a limited amount of "sway"  It attached very easily, with all the pre-drills fitting very well.  TIP:  When possible (in our instance, it wasn't possible) attach the headboard BEFORE setting the box spring/mattress onto the frame.  Even though we got the "cart before the horse," it took only approximately an hour.  A "helper" is a plus just to steady things as they are attached.
