This model bears the GS mark from LGA Nuremberg and meets all safety-related requirements for office and commercial use according to DIN EN 1335 Parts 1-3. It features a continuously adjustable seat height with a top lift. The design backrest is upholstered in breathable mesh and is adjustable in both height and tilt. The comfortable disc seat provides optimal support in the pelvic area. The point-synchronous mechanism can be individually adjusted to the user's body weight and is infinitely lockable. It is equipped with load-dependent braked safety double casters for carpeted floors. This means the chair only rolls under load; when unoccupied, the casters brake to prevent unwanted rolling away.
