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 more practical factors that one should consider include features like lumbar adjustment, height adjustment, and the spring tension at which the chair can recline. Good chairs should also come with a latch that prevents the chair from reclining at all. The top quality chairs will provide adjustable armrests. The armrests should be able to be adjusted in and out from the center of the chair, as well as up and down, and even the length of the armrests should be adjustable.
