  • The angle between your torso and thighs should be between 90 and 110 degrees.
  • The seat pan should be level or slope slightly downward, with a minimum of two fingers width between the seat pan and the back of the knees.
  • The back rest angle should slightly recline and support the lumbar region.
  • Arm rests need to be slightly wider than shoulder width apart and comfortably support the arms.
