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".
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".
Ergonomics are all the rage in the modern age, and no where have ergonomics been pushed to the limits further than in the realm of office chairs. Ergonomics, which refers to the study of comfort and efficiency in the workplace, began by starting with the office chair. It's no surprise that the field of ergonomic office chairs have made drastic leaps and bounds in recent years. Today, ergonomic office chairs offer amazing pain relief for those plagued by typical office ailments. High adjustability makes ergonomic office chairs easily customizable to relieve back pain, neck pain, joint pain, and poor circulation. Even if chairs like the RFM Verte Ergonomic Chair (which is heralded is one of the most comfortable chairs in existence) can get a bit pricey, most ergonomic chairs, such as those from the Hawk Series by Eurotech, come at incredibly low prices that make easy additions to the holiday shopping cart!
