This blanket applies weight to your body's pressure points in order to help promote the production of sleep hormones. It is designed to feel like you are being wrapped in a big cosy hug, which can promote relaxation and help reduce anxiety - hopefully leading to a better, and calmer night's sleep! Weighted blankets have also been used by people with Sensory Perception or Autism Spectrum disorders. One side of this grey coloured blanket has a soft plush finish and the other side is a flat cotton weave fabric. There are two blanket weights that are available, and users must select a blanket weight according to the body weight of the user: 4.5kg (25-55kg) and 9kg (>85kg). The blankets are designed for one person only and are not to be used by infants or small children, please refer to instructions carefully. Composition: Polyester & Cotton, filled with glass beads.
