My only concern when purchasing this headboard was whether or not it would attach to the existing rails on my full size mattress. It fit great! It comes with adjustable screw holes so it easily fits. This will come in very handy if I decide to upgrade from a full to a queen size, major plus! The only issue we had was the directions make it a little difficult to destinguish between correct screw sizes when assembling.  The husband and I ended up using the extra long scews to attach the legs and caused slight damage to the wood. Luckily it was on the back side of the furniture and can't been seen. All in all, very easy to assemble and it looks nice in the room.
