What seat pan angle should an ergonomic chair have?

The seat pan angle should be adjustable — a forward tilt of 5°–10" supports active work positions (typing, drawing, fine work) by reducing lumbar pressure and encouraging upright posture. Most chairs default to flat or slightly rearward tilt, which encourages recline. Multi-function tilt mechanisms allow seat pan and backrest angles to be set independently.
