The proper positioning of an assistant's feet is crucial for maintaining body mechanics and ensuring comfort during dental procedures. When the assistant’s feet are flat on the foot ring or base, it allows for better stability and control while working. This positioning helps distribute the weight evenly, reducing strain on the lower back and legs, which is important during prolonged procedures.

Moreover, placing the feet flat on the foot ring provides a firm foundation that can assist with balance and posture. It enables the assistant to sit upright, minimizing the risks of fatigue and musculoskeletal injuries that can arise from poor seating ergonomics. Proper foot positioning is essential not only for the assistant's health but also for the efficiency of the procedure being performed.
