I'm glad to see this thread. I used to sleep under layers of heavy comforters when I stayed with my elderly grandmother who lived in a drafty old farmhouse. I liked the sensation of the weight, and I also feel I would benefit from the weighted blanket. I had heard the story of the autistic doctor who discovered thru her study of cattle, that providing them with weight on both sides helped calm them. She then took the idea for helping autistic people (she is high functioning autistic). I think this may be the origin of the idea of the weighted blanket. I have a 100% cotton futon mattress (about 2" thick) that I have gotten under for the weight, but it is too bulky.
