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 we have the seat pan characteristics. You should look for seats that have the following characteristics. The seat pan should have adequate depth and width. The material should be comfortable but offer sufficient support and the seat pan should tilt to alleviate pressure on the back of the thighs.
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.
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.
There are some features of a good office chair that you should definitely look for.
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.
