I actually went to their factory and picked up an Adult Sensory Rocker for my daughter, who is autistic. For age 12, she weighs and is as big as an adult. After watching her self stimulate by rocking quite violently back and forth, she's destroyed 2 sofas, and outside the house you can actually see the window shake and vibrate next to the sofa. Got kendra to try the chair, I was afraid with the force she uses she would go backwards with the chair on top of her. Not so! The chair is weighted and balanced in such a way that even full force she barely manages to rock backwards horizontally. I am duly impressed. Kudos Southpaw, and thank you!
