What is Anterior Tilt?

Anterior tilt is a seating function that changes the angle of the wheelchair seat in the sagittal (anteroposterior) plane where the rear aspect of the seat is higher than the front. This facilitates an anterior pelvic position and places the person in a partial weight-bearing stance.

Available on the Edge 3 Stretto, Edge 3, and 4Front 2.
