As we said before, everyone will want something different in an office chair, but there are a few key features that you should look for that every chair should have.
Lumbar support: An office chair with included lumbar support will prevent back pain/tension since it properly aligns your muscles and spine with its contoured shape. Lumbar support can also improve your posture.
Adjustable features: Features like adjustable armrests, adjustable height, and adjustable lumbar support are important for an office chair to have so you can customize the chair to your needs and your office setup.
Cushioned seat: Be sure your office chair has a well-cushioned seat since that's the part of the chair where you will be putting most of your weight on. Look for a deeper seat if you are taller, and a shallower seat if you're on the shorter side. Also look out for chairs with waterfall seats, which are designed to slope slightly downward to relieve the pressure on the back of your thighs and knees.
Caster wheels: You should be able to easily move around your office space thanks to quality caster wheels on your office chair. Pay attention to what type of floor(s) a manufacturer says the office chair is ideal for.
