This model bears the GS mark from LGA Nürnberg 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 has a breathable mesh cover and is adjustable in both height and angle. It includes a comfortable lumbar support seat for 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.
