I lucked out and got one of the self-heating thermal type beds on clearance somewhere many months ago for $4.50 (only one they had) and put it up for Scooter Bug's Christmas gift. He lays on it ALL the time. If I had known he'd have enjoyed it that much I'd have never kept it from him for half a year! It's a little noisy because of whatever is inside, but my boy is sure happy with it.

Good luck with whatever you give to Amy. I hope it helps!
