Weighted blankets, which cost anywhere from $100 and up, are a sleep aid usually made in a duvet style, with the many squares throughout filled with heavy beads. These blankets weigh anywhere from 5 to 14 kg, and manufacturers generally recommend choosing one that's not more than 10 percent of your body weight, although this seems to be just a rule of thumb and not based on scientific study.
