Snooze partner

A snooze partner... 'A partner to keep your bed warm' - in case your are wondering what a snooze partner is. Is there such a thing? I have heard of an activity partner in bed, you know a partner to do things with. Now,now, before you get all worked up, activity as I pointed out to someone I know, can mean a lot of things - reading, chatting.. ahh etc etc :-) Of course there is also that activity that people do in bed, but we are not going to go into that. Anyway, coming back to our snooze partner, I wonder if such person exist! Hmmm.... tricky question indeed :-)
