What is a solution to my cat going onto furniture?

I am moving and will have roommates. I am bringing my two year old cat. They do not want him to go on the furniture. He is used to going onto the furniture at my apartment that I am moving out of. Is there a spray or something I could use on the furniture that will not harm the furniture (from suede type couches to wooden things)? I don't have the heart to spray him with water as he is very skittish. Thanks!
