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.
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.
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.
