Acting much like a tight hug, the Slumber Weighted Blanket will help you calm down & relax, guaranteeing a good night's sleep. The Slumber Weighted Blanket is packed with tiny, hypo-allergenic, environmentally friendly glass beads measuring 0.9-1.1mm in diameter. The resulting delicate yet firm pressure reaches the deep-seated receptors and helps with the release of serotonin and endorphins, chemicals that our body naturally produces to make us feel calm and relaxed. This makes the Slumber Weighted Blanket the perfect sleeping companion for people with insomnia or for people with sensory integration and psychomotor disorders such as autism & ADHD. We recommend that our blanket be approximately 10% of your body weight (not suitable for babies). Specifications: Cover material: 100% microfibre. Filling: tiny glass beads. Gridded square stitching guarantees beads remain evenly distributed. Colour: Charcoal grey. Machine washable on a low, gentle setting with water below 30 degrees.
