The office chair SSI Proline S3 ensures correct seating posture. It features a synchronous mechanism and an ergonomic backrest, and is available in various colors. This swivel chair uniquely addresses the health aspects of sitting at a desk. Its synchronous mechanism promotes dynamic sitting: when you lean back in the chair, the backrest tilts in accordance with your movement. If the pressure from your body continues, the seat also moves with it. This means that the angle between the seat and backrest remains unchanged. The spring force of the backrest tilt can be easily adjusted to your individual body weight using a crank. Additionally, you can adjust the seat depth and seat tilt independently of each other. This is particularly important when people of significantly different heights use the office chair. The integrated lumbar support and the disc seat protect your back, while the knee roll on the seat relieves pressure on your thighs. As a result, even prolonged sitting becomes a carefree comfort experience.
