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".
Having the right back height for your office chair can be of particular importance for those who suffer from back pain and even for those who want to avoid back pain. A good way to determine the back height that will be needed for your chair is to look at your current office chair. If you currently suffer from upper back you will want to look for a chair that's back will come up high enough to support your shoulder blades. Have a friend measure your back in its entirety from the top of the seat on your current office chair up to your shoulder blades to calculate how tall you will need your back rest to be.
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.
