We just got a new queen size bed last Saturday, and we are teaching Malone that he is only allowed up on the bed when he is invited. So far, he has been pretty good about it, and only when he is in a ruckus of a mood does he fly up there with that "catch-me-if-you-can look. He is not allowed on any other furniture, except our deskchairs, and he knows that, too. So I definitely think that you can train Nebo that bed is okay, other furniture is not. Best of luck in pursuading your parents. There's absolutely nothing like a dog curled up next to your legs in the middle of the night.
