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.
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.
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.
