This Queen Size product came with instructions for a BED FRAME and little notes on the options for HEADBOARD ALONE assembly instructions. 
I can figure it out.  But more screws, tools and bolts than I needed.  And no offerings for how to ADJUST for height of mattresses and what holes to use for completing Head Board ALONE instructions or options. 
Took some extra time, but it was very easy.  No need for power tools.  And tools came with, allen and bold wrench with nuts, washers, bolt rings, bolt.  Nice set up.  
I shopped for weight of the headboard since I knew I alone would be owning, but also assembling and later disassembling to pack, move and ship.
