The Thomashilfen ThevoSiiS therapy chair provides a stable and centered sitting position for the user. It gives a minimum of support in order to induce an active holding task. The floor contact of the feet, the firm seat surface, and the back rest give clear perception information and a sensible orientation. The user finds their body center and leads their arms and hands towards this center. Application studies made with children and adult users showed an improved hand-hand and eye-hand-coordination, and to some extent improved mouth closing and swallowing results. These abilities provide a vital edge in different areas, e.g. at home, school or therapy. The users appear more awake and significantly more involved in their environment and situation. The constant impulses, which lead to an upright sitting posture awaken pride and strengthen their self-esteem.
