Innate hyperactivity and attention difficulties keep children with attention deficit hyperactivity disorder (ADHD) out of their chairs, and sensory integration dysfunction keeps autistic children out of their chairs. These children are unable to adequately sense the chair against their bodies. Therefore, they do not feel properly grounded. Instead, they feel extremely insecure. The use of a weighted lap pad may help your child feel the deep pressure of the chair. Some children enjoy the lap pad on their chest or back when going to sleep. The solid blue shade is a calming color and non-stimulating.
