Low back pad- People enter the chair usually in a tucked pelvis. Need to have them sit as deep in the chair as possible with one finger width of space at the front. Cues to provide:
Sit upright and arch your lower back without touching the back supports. OR
Rotate your pelvis forward without touching the back supports.
Turn the dial in until the low back pad meets you and supports you without you having to work at it. You should find it difficult to slouch.
Upper Back Pad- Bring it in to meet them and ask them if they feel balanced. When they say yes, they’re good.
