摘要

The cover has two zones (5, 6), where the zone (5) is to be placed more close to a head (8) of a bed (2) than the zone (6) when the cover is placed on the bed. The zone (5) conserves heat better and/or is heavier by square meter than the zone (6). The zone (6) is to be placed on legs of a sleeper and the zone (5) on his trunk when the cover is used. A third zone of different weight conserves heat in a different manner.
