Unique patented mechanism. See the you tube video instruction.
The Dynamic® is our most advanced work stool. It combines two methods of sitting through a revolutionary patented scissor mechanism, making it possible to sit naturally while alternating active and passive sitting positions.   

Optimal Posture.
The lumbar support automatically comes toward the back and fits the hollow contours. The natural anatomical S-shape of the spine remains even during passive sitting. The small lumbar support ensures optimal freedom of movement and activates stretching of the spine.

Full automatic.
After adjusting the Dynamic® to your individual body dimensions only once, no further adjusting is needed. The Dynamic® has proven its contribution to preventing and improving back complaints.


We are happy to assist you in choosing the right model and optimal settings that fit your body type and work environment best. 

The Dynamic® has an automatic, hands-free tilting mechanism.
Adjustment options:
- Seat height 49cm - 93cm (depending on the selected height of the gas cylinder)
- Seat tilt
- Depth of lumbar support (lumbar pressure)
- Height of lumbar support
- Tilting mechanism (adjusteble degree of resistance with automatic tilting)

The vinyl upholstery can be cleaned with a soft brush and soft soap. 

Do not use cleaners that contain more than 3% alcohol or oil products, it can effect the flexibility of the upholstery. 

We advise the use of the DKL and Schulke cleaning products.


It's best to clean the wheels monthly from dust, hair or other particles that can prevent the caster from rolling freely. The wheel can also be cleaned with a brush and soft soap.


The Dynamic tilting mechanism functions due to the small gas cylinders. In order to keep the hinges flexible we advice to smear the hinges once in 6 months with the silicone spray or synthetic oil. for example W40 or HHS200.
