My exhusband was a fireman and slept against the back wall (made of cement blocks) at the fire station. He had 3-4 quilts on his bed but was always complaining how cold he got at nite in his bunk. I made him a polyester quilt with batting in it and from then on out that was the only blanket on his bunk....no matter how cold the nites got. He said he never got cold again and some nites he had to throw cover off cause he got too hot. It sure made for some warm quilts. lol
