The most popular weighted blanket in the market is the 15lb weighted blanket. It applies just enough pressure without going overboard, so you do not have to worry about it being too much for you. It is also perfect if you love moderate pressure and still want a blanket that does not always weigh you down. Most cooling blankets are of this weight since they can be made breathable without an issue.
The only thing you need to remember is if you love to feel the pressure of your blanket on your body, this might not work for you. Always consider your current needs and what makes you fall asleep fast enough.
