The size of the back of the chair is one of the most important features. For an executive chair to be truly comfortable, the top of the back of the chair should be no lower than the middle of the back of the person's head who will be using the seat. In a truly comfortable office chair, a person should be able to lean back and have their head rest against the back of the chair or a headrest. Many lower quality chairs have backs that extend up almost to the back of a person's head, but not quite. If a person leans back in one of these chairs, their head hangs over the back and it is quite uncomfortable.
Having the right back height for your office chair can be of particular importance for those who suffer from back pain and even for those who want to avoid back pain. A good way to determine the back height that will be needed for your chair is to look at your current office chair. If you currently suffer from upper back you will want to look for a chair that's back will come up high enough to support your shoulder blades. Have a friend measure your back in its entirety from the top of the seat on your current office chair up to your shoulder blades to calculate how tall you will need your back rest to be.
The last factor to consider is how adjustable you will need your ultimate ergonomic chair to be. If you work for more 8 or more hours a day, you will likely need a highly adjustable chair that allows you to recline throughout the day with tilt lock and tilt tension control(allows the user to choose the amount of tension needed to recline back in their chair and to lock their chair in the upright position when typing then unlock when recline is desired). If you are a taller or shorter individual, it may be beneficial to have a seat slider adjustment that allows you to determine make your chair's seat depth either longer or shorter.
