The single most overlooked feature to consider when looking at buying office chair is the base. It is standard for these chairs to have casters or wheels. However some chairs come with only four spokes, or for legs with wheels; others with five, or six. It is important to get a chair that has more than four legs. With only four legs, depending on the orientation of the chair, it can be easy to tip out of the chair. Because of the head rest, someone sitting in the chair will be inclined to sit back and lean back in the chair. If the chair has only four legs, i.e. a base with four wheels, if they are leaning back between two of the legs, the chair could tip over backwards. (The taller back of an executive chair makes this more likely than with a smaller, standard office chair.) With five or more wheels, the chair becomes more stable. Of course, the other determining factor of the stability is the width of the base. Again, high-end executive chairs will have a wider base.
Next you will need to figure out the seat height range necessary for you to be able to keep your feet flat on the floor while working(or on a foot rest) and work with your height. You will also need to take into consideration the height of your desk to ensure your chair will fit underneath your desk if needed, especially if you would like a chair with armrests. Most standard desks are 29" measured from the floor to the top of the desk, however some have higher workstations or adjustable desks that can be lowered and raised if needed. If you are a shorter individual a standard cylinder that comes with most office chairs may be too tall for you causing your legs to be bent at an awkward angle. The same can be said for taller individuals who need a longer cylinder and higher seat height adjustment range. Certain specialty ergonomic office chairs offer different cylinder size options to accommodate individuals of any height from children 4' tall to adults that are 6'8".
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.
