Product details
The Sitness 20 by Topstar is an innovative fitness stool specifically designed for use in the workplace. It offers an ergonomic seating alternative that promotes back training while working. With its original Walser patent, the stool allows for stepless seat height adjustment, operated via a practical ring release lever located under the seat. The special deep suspension provides a horizontal rocking effect, which can be individually adjusted through a pressure regulation in the air cushion base. The footplate made of polished aluminum and the rubber tires not only give the stool stability but also a modern design. The Sitness 20 is designed for adults and meets all safety-related requirements, as confirmed by the GS mark from LGA Nürnberg. It is an excellent choice for anyone looking to improve their sitting habits while staying active.
