Larger than the regular Senseez, this set of two lightweight, fun-shaped, tactile, vibrating cushions offer a gentle sensation when they are squeezed or sat on. For all teens and adults who have difficulty sitting for short or long periods of time, who get distracted easily, who have trouble concentrating, who could use some help with relaxation, who have difficulty calming down and who have difficulty getting to sleep. Cordless and battery operated (2 x AA batteries not included).
