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.
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".
Once you have determined the type of desk chair you need, you will then want to look at the features you will want included in your chair, including the option of casters or glides. Most office chairs come standard with rolling casters which allow you to move quickly and efficiently from one spot to another. Chairs that have glides are stationary, meaning they do not move unless you pick the chair up yourself. A desk chair with glides would be ideal for extended height applications where your work station is higher than a typical desk and you need a steady chair to work on your projects. Many architects, artists, painters, and lab personnel opt for this style of seating as their work requires them to sit still. Some chairs also come with the option of having pressure breaking casters, which lock to prevent movement while you work whenever pressure is exerted on the wheels.
