The Topstar Net Pro 100 is an ergonomic office swivel chair that combines a modern look with noticeable sitting comfort. Its newly designed backrest has a double mesh covering - front and back - and thus ensures a fresh seating climate, clear lines and stable, flat support for the back. The height of the backrest can be adjusted and, if necessary, locked in place so that it can be quickly adjusted to different body sizes and working positions. The synchro-mechanism coordinates the movement of the seat and backrest for gentle posture changes, while the adjustable rocker mechanism regulates the resistance to suit the body weight and enables balanced, controlled reclining. The special intervertebral disc seat with pronounced knee roll straightens the pelvis and supports the natural S-shape of the spine. This distributes the pressure more evenly, the thigh support remains comfortable and the back is noticeably relieved, even during long periods of work. All controls are easy to reach, the adjustments are intuitive and promote an upright, relaxed sitting posture at the desk. The material and workmanship are designed for daily use: The mesh remains dimensionally stable and breathable, the mechanism works quietly and is durable. The trade magazine FACTS rated the Net Pro 100 as "very good", confirming its harmonious combination of ergonomics, function and quality. Whether in the office or home office, this swivel chair offers reliable support, a modern appearance and precise adjustability that facilitates healthy, concentrated work.
