The Ultra cushion is a comfortable and clinically effective positioning cushion. The Ultra cushion's shapes allow for better control of the pressure distribution on bony prominences (ischium and coccyx), while ensuring controlled weight distribution over the cushion surface. The Ultra helps optimize the users posture by preventing the pelvis from sliding forward (backward tilt) or laterally. The surface has a dispersion-foam (viscoelastic) covering to enhance comfort.
