What is the correct sitting posture in an ergonomic chair?

Correct seated posture at OfficeFurniture2go.com: lumbar in contact with support, shoulder line over hip line, ear over shoulder (cervical neutral), elbows at desk surface height. Posture variation every 20–30 minutes is equally important — dynamic posture variation is part of the ergonomic design intent. We include posture guidance in our workstation commissioning.
