Jax gained access to the bed when I began keeping him in my room with me at night as opposed to the kitchen or his crate. He got too destructive early on and now spends my work day crated, so I felt bad about crating him or confining him to the kitchen at night as well. So the solution was to bring him to my room to sleep. The cat used to sleep in the bed nightly up until that point, but even now, he has started to come back around. In any case, Jax doesn't go up the stairs except to sleep, and when he follows me up, he instantly goes for the bed. It's just me, so I've not objected, once I got him into the habit of settling down when coming upstairs. However, my fiance will be coming out for a month during the summer and it'll be rather interesting to see how that all works out, as he's begun sleeping in the bed all night. Initially, he'd go to the floor after a half hour or so. No longer, now he actually will curl up at the head of the bed on a pillow more often than not. I figure so long as he's calmed down and behaving himself, and it's a routine of only coming upstairs to sleep, it's pretty well controlled and fine by me.
