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.
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 more practical factors that one should consider include features like lumbar adjustment, height adjustment, and the spring tension at which the chair can recline. Good chairs should also come with a latch that prevents the chair from reclining at all. The top quality chairs will provide adjustable armrests. The armrests should be able to be adjusted in and out from the center of the chair, as well as up and down, and even the length of the armrests should be adjustable.
