With the Ahrend Six Office Chair, you will always maintain a good sitting position. The Six Office Chair features a synchronous mechanism that operates with resistance. When you change your posture, the chair applies the right pressure to the right points. The amount of back pressure depends on your body weight. This ensures that your seating is always ergonomic, reducing the likelihood of physical discomfort. You can adjust everything on the office chair while seated, from the armrests to the backrest with net covering, and even the lumbar support for added back support. The net covering on the backrest provides ample ventilation, giving you even more seating comfort while you work.
