These blankets are designed for use by one person and the weight of the blanket should be no more than 10% of your body weight.
Promising review: "After reading other reviews on weighted blankets, I decided to go with Luna. (I have bought two now, one as a gift) I love that the material is organic cotton, and the beads are not made of plastic. Thr material is cotton so it is light but strong. I have used this blanket for three or so months now. Having battled insomnia, restless legs, joint pain, and muscle pain, I had read that a weighted blanket could help. Honestly, I hardly have sleepless nights now. The blanket isn't too heavy but just heavy enough. I did get the 15-lb, technically too heavy for my weight according to studies, but I love my blanket!! Before I had this blanket there were many nights I was awake until 3 a.m. due to insomnia and pain. Now, usually within a half hour of winding down, I am asleep! It calms my restless legs , and really lessens muscle and joint pain! Blanket is sturdy, holding up well. Totally worth the money." —sunshine
