Which seating component is MOST indicated for a user who presents with significant posterior pelvic tilt and sacral sitting posture?

When evaluating a client for a custom manual wheelchair, which measurement is MOST critical for determining proper seat width?

Seat width is determined by measuring the widest point of the hips or thighs and adding approximately 1/2 inch of clearance on each side to prevent pressure and allow mobility.
