Sitness 4D

Sitness 4D – dynamic sitting with active support

The Sitness 4D is a dynamic stool that moves with your body. Thanks to the 4D mechanism with free-floating tension and compression springs, combined with a 360° rotating seat shell and body, you automatically maintain micro-movement. This activates back muscles, relieves pressure on the spine, and supports a natural, upright sitting posture—without you having to consciously pay attention. The result: greater focus, less tension, and a nearly weightless sitting experience.

Certified health
The Sitness 4D is AGR-certified by "Aktion Gesunder Rücken eV." This seal of approval stands for back-friendly products that have been independently and expertly assessed.

Made in Germany
The stool is produced and inspected in Germany, which ensures high quality and reliable durability.
