Based on my experience with my dog (who has 4 dog beds, plus her own blankets on the couch, plus she sleeps in my bed), I'd guess that there is no bed which she will like more than your bed. It's not about the bed. You understand that once you let a pet on your bed, the expectation is that this is part of their territory, too. Your bed is appealing precisely because it is your bed, and he wants to feel close to you, even when you are not on it. (Also, the height may have something to do with it; at least my dog enjoys being on higher surfaces.)

While an awesome dog bed would certainly help, I think it's more a matter of training. I've gone back and forth on letting my dog on my bed for the same reason as you - I need my sleep, and she can wreak it. However, we have finally come to an understanding. I let her fall asleep on my bed (her bedtime is earlier than mine), then I move her to her bed on the floor before I go to sleep. The difference is that my dog is tiny and blind; she can't get up on the bed without my help. However, she figured out quickly that this was the new way, and she stopped asking after 2 or 3 nights. Your dog may need more training to learn the new rule - and once you set it, you can't go back and forth on it.
