Versatility
This is something you should think about if you're picking up a chair for your stationary office. The home office chairs can be selected exactly to the needs of the person who will work on it, but the situation is different when it comes to bigger offices.
Usually, a company has at least several employees, and in many cases even several dozen or several hundred.

This is the reason why the office chairs should be as versatile as possible. It means that it should give you the ability to adjust the height and size of as many elements as possible. This way, everyone will be able to make the chair as comfortable as possible.
