The Topstar Sydney Pro office chair combines first-class comfort and ergonomic design to provide you with optimum support during your working hours. With a contoured backrest that is specially shaped in the lumbar vertebrae area, the chair offers targeted support that can be infinitely adjusted in height. This enables an individual sitting position that relieves the spine and prevents tension. The synchronous mechanism of the Sydney Pro enables a dynamic sitting posture and can be precisely adjusted to your body weight. This ensures that the backrest and seat move synchronously, which not only increases comfort but also improves your posture while you work. The backrest can also be locked so that you can maintain the desired position. The comfortable hollow seat with knee roll provides additional comfort and a pleasant seat surface that allows you to sit for long periods without tiring. The chair is complemented by 1D armrests, which relieve the strain on the arms and ensure greater ergonomics. Equipped with carpet castors, the Topstar Sydney Pro offers effortless mobility on various surfaces, making it the ideal choice for any office or home office. With its sophisticated design and ergonomic features, this office chair is perfect for anyone who values a healthy and comfortable workplace.
