Hi guys, thinking of getting a buttkicker gamer 2 for my VR setup. It seems the attachment is for the center pole of office type chairs. I have a standard 4 legged chair which I like, so was just wondering about mounting options in this case - do you screw it onto the underside of the chair? attach it to one of the 4 legs? Cant find the full manual on the web so any feedback appreciated :)
