Fleshing this out further, let's say a company advertises free shipping on their church chairs once a certain quantity of chairs are purchased to select geographical regions of the country. One of their chairs they sell for essentially $33.00 each, once there are a minimum of 100 chairs, purchased as a part of the order and also include "free shipping" for those chairs to about 20 different states. In this case they may purchase those chairs from a Chinese factory for about $13.00 a chair. They bring them to this country, warehouse them, sell them, and then deliver them. Their costs for all of these items is perhaps another $13.00 or so per chair. They then sell them for $33.00 a chair and all of their costs are covered and they make a nice profit. All through the process though they continue to state they are offering "free shipping".
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.
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.
