Be Square and Be There
An All About Down® comforter is stitched into billowy, sewn-through squares that keep the goose down in place where it keeps you warm. The misconception that each line of stitching is a cold spot doesn't apply to a down comforter because the amount of top-stitching is miniscule compared to the area that the goose down covers and you are not using your comforter in a desperately cold environment.
Other Comforters' Baffled Squares - Comforters with baffled squares have small openings in the corner of each internal square through which the down is blown. After the comforter is closed, these corner openings remain. Gravity being what it is, the down gradually migrates to the lowest point over the side of the bed leaving you shivering and wondering why your comforter won't keep you warm.
