What does a seat riser do?
A seat riser such as the Sitness 20 ensures you sit at the right height at your desk or workstation. This product is ideal when your existing chair is too low, or when you regularly switch between different workstations and want to maintain a consistent seat height.

Why choose this size?
With seat dimensions of 400 x 400 mm, this seat riser offers enough space for comfortable sitting without being unnecessarily large. The round shape suits a variety of body types and promotes a natural sitting posture. The height adjustment range of 420 to 550 mm gives you the flexibility to find exactly the right position.

Stable construction with freedom of movement
The Sitness 20 combines stability with dynamic sitting thanks to its air-pressure-dependent sideways tilt. This means you can move slightly while seated, which is good for your posture and blood circulation. The polished metal base plate and rubber bands provide a sturdy foundation that can support up to 110 kg.

Practical tip for use
The stepless height adjustment works intuitively: you adjust the height by shifting your weight while operating the lever. The 100% polypropylene material is easy to clean with a damp cloth. Make sure the seat riser stands on a level surface for optimal stability of the rubber bands under the base plate.
