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.
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.
Then there is the backrest horizontal movement or the ability to move backward and forward. This is not the same as the tilt feature. This is a feature that actually either increases or decreases the distance between the back of the chair and the seat of the chair. Not all chairs have this feature and while it may cost more it is something to consider as it will provide further comfort on an individual basis.
