The woman lives in a residential care facility for people with dementia. Her everyday life is characterized by constant physical restlessness and wandering in the corridors as well as severe mental unrest and a pronounced collecting mania. She cannot remain sufficiently calm to concentrate on individual sensory inputs in activities such as eating and exercising. When using the Protac SenSit^® Straight ball chair , she is comfortable changing position from standing to sitting, due to the height and firmness of the chair’s edge. The upright position allows her to have a sense of security and control. She is better able to relax and find peace. She can independently get in and out of the chair. Subsequently, she can remain sufficiently calm to remain focused in activities, for example eating a meal without wandering around. The chair has a really good effect on her physiclal and mental restlessness.
