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.
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.
And of course the chair itself should be stable. You don't want a chair that is wobbly. To ensure this you should look for a chair with a five pronged base.
When purchasing an office chair, the first thing you want to get, if possible, is a trial period. Many distributors will allow a week. That way if there are any problems or if the chair is uncomfortable after long periods of sitting you can return it. You can't possibly know if a chair is going to be comfortable after just a few minutes of sitting.
The first thing that is very important is a backrest adjustment. A backrest adjustment can prevent or at least help lessen the discomfort that happens when sitting for long periods of time. There are some things about the backrest that you should look for.
Then there is the backrest tilt which allows the person using the chair to either recline (lean back) or incline (lean forward) and adopt variable postures in between these two positions. Most people find a slight reclining position to be the most comfortable.
