Weight, as a sensation, is inhibitory and calming to the central nervous system. As a result, the gentle, all over pressure applied by a weighted blanket, will help anxious, fidgety children to sleep faster and stay asleep longer. The Sleep Tight weighted blanket was designed with much care and attention to detail, by a pediatric occupational therapist. The unique out-out design at the neck produces a snug, comfortable fit over the arms and sholders. The blankets are filled with PET pellets and covered with soft cotton corduroy. They are machine washable and dryable on a low heat setting. Covers are available to make washing easer. Perfect for use at home and in therapy clinics. This is a durable innovative product of superior quality.
