Some people just like lots of heavy covers. My step-daughter piles on the blankets and quilts when she goes to bed.
My daughter needs a hot rice bag for her feet a lot of the time, and I use a rice bag too when I go to bed. There were times when I put a large pillow on the bed right over my feet (for the weight) to get them to warm up. Now I use the hot rice bag. Works slick.
