Some people have a misunderstanding about ergonomic office chairs. They believe that ergonomic chairs can solve all the problems of poor sitting posture. Although an ergonomic chair makes a great contribution to improving the sitting experience, it is not a panacea. To develop the correct sitting posture, the way you sit on the office chair also plays an important role. The first step is to make sure that you have adjusted your lumbar support to fit your lower back. Ideally, lumbar support should provide adequate support for the lower back. Remember to adjust the height of the seat cushion of the chair so that your feet are flat on the floor, your legs are perpendicular to the floor, and your thighs are parallel to the floor. In addition, tilt the backrest appropriately. This can usually be achieved by flipping the handle under the cushion. At the same time, you can also adjust the position of the armrests according to your height. Don’t forget to adjust the height of the seat so that your view of the computer monitor remains at eye level.
