Do you let cats sleep in your bed?

I have one cat that sleeps in my bed, he sleeps along my side stretched out beside my ribs and therefore isn't bothersome to me. As for my other two cats they tend to sleep wherever they find fit, though I have on occasion found them napping on my bed during the day. Rusty is my cat that sleeps in the bed at night, he is so certain that he belongs there that anytime we are up later than usual he will start running back and forth to us and the bed meowing hysterically until at least one of us climbs into the bed.
