It comes with two mounting plates, one for a metal bed frame that is more removable and one square plate that is more permanent. You can use whatever you want for attachment hardware, depending on what you are attaching it too, so I see no reason that you couldn't attach it to the floor, whether wood or concrete, as long as you have the proper hardware. Mine is attached to the wooden side rail of my bed using large wood screws. The plate stays there and the case attaches from the inside using bolts with thumb screws, so I can take the case off and carry it like a briefcase if I want to without having to remove my mounting bracket. So, if I'm going to be staying in a hotel, I can still attach it to my bed frame using the other bracket.
