SERA is the world's first adjustable weighted blanket, fully washable and can be configured to weigh from 7 to 28 pounds. My vision was to create an adjustable totally customizable weighted blanket for people who suffer from sleep and anxiety disorders. Our blankets have also been used by children with ADD, PTSD, Aspergers and Autism as well as seniors with Parkinsons, Dementia, and Alzheimer's. The blanket's weight is sewn into strips which then get pulled into the channels of the cover with a custom Sera tool. The weighted strips come in different weight increments. https://bit.ly/SeraOnKickstarter
