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.
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.
