“…The preferred seating angles proposed in ANSI/HFES 100-2007 (Human Factors and Ergonomics Society, 2007) suggest either fixed or adjustable seat pan angles from 0° (horizontal) to 4° rearward. More recently proposed seat pan backrest angles are at least 90°, and if it is adjustable, the backrest angle should recline at least 25° from vertical (Dainoff, Maynard, Robertson, & Anderson, 2012). Presuming there is a reasonable chair fit, relaxing fully onto the chair back will support the spine in a midline position, or neutral posture between forward and backward bending.…”

Observing seated posture is important for ergonomic assessment; proper chair fit and chair adjustment should be considered for the entire context of work demands. Recommending only one seated posture presumes that all seated work has a similar location of visual targets, shoulder reach distances, and support surfaces. The nature of work tasks may influence posture more than does chair adjustment, and field observation of sitting should focus specifically on lumbar spine posture when work may cause forward movement of the torso. I suggest that the position and movement of the pelvis in relation to the torso is a reasonable and important indicator of spinal posture.

“…As elucidated by Serfaty et al (1997), the performance of experts is impacted by the working environment, task and domain of the problem being studied. These are the constraints of interest in the perception-action cycle outlined by Dainoff et al (2012) and are important considerations in the evaluation of the system and the participant.…”
