Modern office chairs use hydraulics or pneumatic lift mechanisms that enable the user to easily move the chair up and down. This then allows them to use the ergonomics.
Ergonomics is a combination of anatomy, physiology, psychology and engineering. Ergonomics is concerned with how people interact within their environment and how their environment can be adapted to make sure that there are safe and effective work practices taking place in the office.
An ergonomic chair is made to specifically support the body during those long hours of sitting in the office chair. The ergonomic chair has a range of features that are put in place to support the user’s health whilst they are utilising the chair and working from their desk. Ergonomic chairs are fitted with mechanisms that allow the chair to be adjusted, you are able to change the position of the seat fast and effectively.
Hydraulics and pneumatics are terms that are used for the usage of fluid power. Hydraulics utilise liquid metal that is incompressible an example of this would be oil. The oil enables the machinery to move, pneumatics on the other hand use a gas that is compressible such as air or pure gas to enable the same machinery movement.
The hydraulic system is generally used for heavier loads, whereas the pneumatics system is used for lighter loads such as office chairs as it is both lighter and a lot easier to store. Both hydraulics and pneumatics make use of the same technology, though the pneumatics system is generally used for office chairs.
