Protac SenSit – Sensory Learning Station

A specialized sensory-stimulating ball chair designed to reduce physical and mental unrest while sharpening concentration for individuals with ADHD, autism, dementia, brain injuries, or motor agitation. The chair, along with its four enveloping side wings, is filled with patented plastic balls that shift under body movement. This unique design targets trigger points in the neck, arms, and back, applying deep, dynamic proprioceptive pressure to enhance body awareness, soothe the nervous system, and stabilize posture.
