This stool brings movement into your working day: the flexible sideways motion keeps you active and relieves your back. Infinitely height-adjustable, so always tailored to your desk.
When do you choose this product?
When do you need an active stool?
This Topstar Sitness 20 stool is designed for people who work standing up a lot but regularly want to sit down for a moment. Active sitting engages your muscles and keeps your posture in motion, which is ideal for workplaces where you alternate between standing and sitting.
Why choose this size and height?
With a seat height that is infinitely adjustable from 420 to 550 mm, this stool suits different body heights and working heights. The round seat measuring 400 x 400 mm offers ample seating area without taking up too much space, which is practical at compact workstations.
How does the sideways movement work?
The lateral movement of this stool is adjustable by air pressure, meaning you can decide for yourself how much movement you want while sitting. This active motion activates your stabilising muscles and prevents a static sitting position. The rubber wheels in the base ensure smooth movement.
Practical details for daily use
The stool has a load capacity of 110 kg and is upholstered in 100% polypropylene, a plastic that withstands daily use. The polished metal footplate provides stability and a professional appearance. Thanks to its compact design, you can easily slide the stool under your worktop when you are not sitting on it.
