Then there is chair height adjustment. All office chairs must have this feature as people with longer legs will probably want the chair seat higher off the ground otherwise they may begin to feel their legs cramp up.
For starters, there is the backrest height. You want to try to find one that will allow the user of the chair to provide maximum support to the lower portion of the back. The height will vary from person to person so that backrest itself must be adjustable.
As for armrests, they should not interfere with the work that needs to be done but should be comfortable and provide support for the arms. In general if wide movement is needed armrests should be avoided.
