Unique technology in the Mygo Seat shell provides optimal, adjustable/customizable support for the trunk, pelvis and legs to create and maintain a solid foundation for the seated posture. The highly adjustable sacral support accommodates fixed pelvic rotations and obliquities, as well as both anterior and posterior tilt. Seat depth is individually adjustable for right and left leg to easily accommodate a leg length discrepancy. The standard split seat base also delivers 13° abduction (moving leg away from midline) and 10° of adduction (moving leg towards midline) to accommodate a range of challenging hip postures including windswept hips (Windsweeping is identified by the abduction and external rotation of one hip with the adduction and internal rotation of the other, giving the impression that legs have been 'swept' away together to one side of the chair. It is termed right or left according to which side of the body the knees are directed.)
