This sitting stool lets you move actively while seated, thanks to the flexible foot base and 360° swivel. Easy to carry thanks to the built-in carry handle, and you set the height exactly how you like.
When do you choose this product?
What does this product do?
This stool is designed for dynamic sitting, where you stay actively in motion while you work. Thanks to the saddle-shaped seat, you automatically adopt a more upright posture, which improves your posture and reduces tension in your back and neck. The stool is ideal for workstations where you regularly stand up and sit down again, such as at high worktops or standing desks.
Why choose the Sitness 4D variant?
What makes this stool special is the integrated spring mechanism located in the core of the frame. This technology allows you to make small movements in all directions while seated, which keeps your muscles active. The specially shaped base also allows sideways movements, giving you more freedom to move naturally while you work.
Comfort and adjustment to your workstation
The height adjustment from 470 to 580 mm makes the stool suitable for different body heights and worktops. The polyester cushion measuring 370 x 370 mm provides sufficient seating comfort without being too soft, so your active sitting posture is maintained. The 360° swivel function ensures you can move easily without having to shift the stool.
Practical tip for use
Thanks to the integrated carry handle, you can easily move the stool between different workstations. Start gradually with using this dynamic stool, as your muscles need to get used to the more active sitting posture. Begin with short periods and slowly build up to longer periods of use.
