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.
The first step towards finding your ultimate ergonomic office chair is to figure out the dimensions needed to accommodate your body size. First, determine the seat depth(length of the seat) that will be required for your new chair. This is a crucial step because a chair that is too long will put pressure on the back of your knees and a chair that is too short may not fully support your legs. A good way to determine your ideal seat depth is to turn towards your current office chair; if your current seat depth already works for you then make sure your new chair will have the same seat measurements. If it is too long, look for a chair with a smaller seat depth and vice versa if your chair's seat is too short. If you prefer a softer sit while working look for a chair that offers seat foam upgrades such as a gel seat or triple density foam otherwise some chairs come standard with an extra thick seat.
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.
