ERGONOMICS

The aspects of health, safety and comfort form the core of ISRI seat development.

Biological functions and needs of the human body as well as a close examination of the work situation guide our seat design.

Focused on people

Seat development for humans.

To meet the requirements of an ergonomically designed seat, it is important to understand the human body with its biological functions and needs.

It is also necessary to take a close look at the work situation:
In what way is the seat used?
How many hours a day is it used?
What conditions must be met to improve working conditions?

These are the tasks we set ourselves in order to ensure that the driver can adjust the seat optimally and so improve health and well-being.
