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".
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.
If you experience neck pain look for a chair that comes with an adjustable headrest. Again you will need to measure your back to ensure you do not pick a chair that has a back that is too high or too low, otherwise your headrest may end up turning out to be detrimental rather than helpful. Many people suffer from lower back pain from having a chair that does not have proper lumbar support which is why it is crucial to find a chair that offers built-in lumbar support, adjustable lumbar support, or air lumbar support to prevent lower back pain.
