This Weighted Blanket Offers a Natural Way to Help Calm Your Body for a Restful Night of Sleep. It is knitted evenly so the weight is distributed evenly and can hold up even for years to come. And the weight comes from the chunky yarn which filled with 100% hollow fiber, so it is sturdy and long lasting and beads free. This Weighted Blanket maintains superior breathability and ventilation because of the free airflow via loops on the blanket, so when it laid on you or wrapped around you, it won’t retain too much heat, but only give you soothing and relaxing hugging feel.
