Product details

The Sitness 20 by Topstar is an innovative seating alternative specifically designed for back training at the workplace. This fitness stool combines ergonomic design with functional features to promote a healthy sitting posture while activating the muscles. Equipped with the original Walser patent, the Sitness 20 offers a stepless seat height adjustment, which is operated via a practical ring release lever located under the seat. The special deep suspension allows for a horizontal rocking effect that can be individually adjusted through a pressure regulation in the air cushion base. The polished aluminum base plate ensures stability and durability, while the included air pump allows for easy adjustment of the seat height. The model meets all safety-related requirements and bears the GS mark from LGA Nürnberg, indicating its tested quality.
