When do you choose this product?
What does the Sitness 4D stool do?
The Sitness 4D is an active stool that helps you stay in motion while sitting. Thanks to the built-in spring mechanism and the specially shaped base, you can make sideways movements, keeping your muscles active and improving your posture. This makes it an ideal solution for workplaces where you want to alternate between traditional sitting and active sitting.
Why choose this compact size?
With seat dimensions of 370 x 370 mm, this stool offers a compact seating surface that fits perfectly in smaller workspaces. The saddle shape encourages a natural seated posture in which your pelvis tilts slightly forward. Thanks to the 360° swivel function, you can easily move in different directions without having to reposition the stool.
Height adjustment for optimal comfort
The adjustable seat height of 470 to 580 mm lets you adapt the stool to different desk or worktop heights. This range makes the stool suitable for most standard workplaces and various body sizes. The 100% polyester upholstery with comfortable padding provides sufficient comfort for prolonged use.
Practical mobility thanks to the built-in handle
The integrated carrying handle makes it easy to take the stool to different work locations. You can conveniently move it between workstations or store it away when not in use. This makes the Sitness 4D particularly practical for flexible work environments where multiple people share the same space.
