The seat height of this office chair is between 40.8 cm (low) and 81 cm (high), depending on the gas spring. The standard gas spring allows a seat height of 47 to 65.5 cm, the high chair gas spring from 55.5 to 81 cm.

The difference to the Xtreme model lies primarily in the gas spring and the seat height: the Xtreme model is equipped with a 265 mm gas spring, which allows a seat height of 55.5 to 81 cm and is particularly suitable for height-adjustable standing workstations. The standard version has a 200 mm gas spring with seat heights from 47 to 65.5 cm. The Xtreme model also has a lockable backward seat tilt and a forward seat tilt adjustment of 2°, which is not explicitly mentioned on the standard model.
