I agree with others that poodles vary and that if you want a cuddly dog, try to select a cuddly puppy. In my experience poodles are more cuddly and affectionate on average than, say, a sighthound, who might be aloof with almost everyone except their chosen person/people. The poodles that I've known have mostly been friendly and loving but not all have been snugglers. Even the less snuggly, more playful poodles I've known have enjoyed a little head scratches on the knee during down time.
Oona, who is my own first poodle, is only 14 weeks but is turning out to be the wonderful snuggler I had hoped for. She loves to be near me and in my lap, or rubbing on my legs, and to be scratched, patted, belly rubs, etc, and she prefers to fall asleep nearby or touching me if she has the choice, but when she's had enough, she moves away to sleep or play. She is quite cuddly like this with her immediate family members but so far still a little reserved with strangers. She has gotten to the point of being friendly and accepting pats from others outside our household but doesn't seek out strangers' physical attention yet, and may not wind up that kind of personality. We'll see.
The golden/poodle contrast that others have brought up is a good one - goldens are probably a better bet if affection is your # 1 priority - but I have to say I prefer the style of snuggling I've experienced with poodles - enthusiastic but not overzealous or demanding (Your mileage may vary! I've known several poodles well, but not that many individuals in total). And I can't handle the golden coat. My in-laws' golden retriever will sit right on your feet or in your lap if he can, and request continuous patting, to the point of turning around and staring pointedly at you if you stop the pats, or, my MIL reports that he gently takes her hand and puts it back on him. He will take what affection you offer and ask for more until you tell him to leave you alone. Even the cuddly poodles I've met have not been as much of a bottomless pit for affection. At the same time, he only does this with people he knows indulge him (ahem, who me?), and willingly goes to settle down elsewhere when told to by my FIL.
