With this office chair, you sit comfortably all day and can adjust your working posture as required. The high back rest with an adjustable headrest provides good relief for the neck and shoulders. The Amer office chair is equipped with a synchronous mechanism with a sliding seat, which means that it ergonomically follows the body's movements. While you lean back, the seat also tilts slightly forward, which helps the body remain in an ergonomic position. This promotes better posture and reduces tension, especially during long periods of sitting. In addition to the synchronous mechanism, the chair has a function that allows the seat depth to be adjusted (sliding seat). This means that the chair's seat can be moved forwards or backwards to individually adjust the sitting position. The arm rests are height adjustable and the chair features a lockable synchronous tilt and an adjustable seat depth. The seat height is adjustable between 450 mm and 570 mm. The base is made of chrome-plated steel and gives the office chair both stability and an attractive appearance. Choose between an office chair made of black leather or a textile version with good comfort. The DIN EN 1335 standard for office chairs: The DIN EN 1335 is a standard that specifies dimensions, safety requirements, and safety tests for office chairs, such as the adjustability of seat height, seat depth, and back rest. The standard aims to ensure that office chairs comply with ergonomic and safety requirements to guarantee a healthy and safe working environment.
