First things first, you've gotta master your chair's features and understand it's components. Nearly every ergonomic swivel chair manufacturer after 2010 will come standard with a few basis components. From bottom to top you should have a mobilized base, pneumatic cylinder, ergonomic mechanism, seat, arms, and back. These components work together to provide you with the support needed to make it through those long days at the office.
Those who are afraid to adjust, suffer. They seldom reap all the benefits their chair has to offer. Don't take a set it and forget it approach to office comfort. Instead, show your computer chair a little TLC to improve performance. When working, keep your back in contact with the chair at all times. If you hunch away from the chair to type on your computer, your spine pays the price!
Additionally, you'll want to keep your feet flat on the ground and facing forward for ergonomically correct operating. Don't use the base of your chair as a foot rest. It restricts blood flow that leads to cramping and even pain. When this happens, productivity levels drop.
Once you've learned to love your chair and it's features, you need to learn to care for it. About once per month, check the wheels on the 5 star base. If they're clogged with any debris, remove it. Next check the screws and bolts that hold your tasking chair together. If any of them are loose, tighten them up to prevent a breakdown. Last but not least, got through your chairs functions one by one. Ensure they are working properly. If you hear any squeaking, a little oiling might be necessary to keep your chair performing at the levels you've come to expect.
In the long run, the office chair is only as good as it's owner. Event the most expensive ergonomic executive chair won't be worth much if you don't properly care for it. Once you've formed sustainable posture and chair maintenance habits, you'll be dominating your work day for years to come.
