The point is actually to have it feel like the lead vests that they use at the dentist. The weight helps calm the muscles and helps the user feel comforted (obviously not everyone). They are often used for people with Autism but are often helpful for people with Restless Leg Syndrome, sensory issues, depression, etc. It's a fairly unknown concept but I've heard it done wonders (I'm trying to make one of my own).

What is the purpose of the weights and then search out solutions to that. I would hate to sleep under something that would make me feel I was in the dentist chair with the XRay protector on me.
