Most modern office chairs<\/a> use hydraulics or \u2018pneumatic\u2019 lift mechanisms that allow the user to move the chair up and down easily. This enables them to use the science of ergonomics.<\/p>\n

What is Ergonomics?\u00a0<\/h3>\n

Ergonomics is a combination of disciplines such as anatomy, physiology, psychology and engineering. Essentially, it’s concerned with how people interact with their environment and the ways the environment can be changed to ensure safe and effective working practices. For example, ergonomics can be applied to physical objects such as chairs and desks, or it could be applied to a system, such as communications between different departments.\u00a0<\/p>\n

Ergonomic chairs<\/strong><\/h2>\n

An ergonomic chair is designed specifically to support the body during long periods spent sitting. They have many features that are designed to improve posture and comfort and to help support the health of the user whilst they are working at a desk. These ergonomic chairs usually have mechanisms to help to adjust the seating positions quickly and easily \u2013 using hydraulics via a lever below the chair.<\/p>\n

What does the term \u2018hydraulics\u2019 mean?<\/strong><\/h2>\n

Hydraulics \u2013 and pneumatics \u2013 are the terms used for applications of fluid power. Hydraulics uses incompressible liquid metal (such as oil) to enable machinery movement, and pneumatics use an easily compressible gas such as air (or a pure gas) to enable the same functionality. Hydraulic systems can move heavy loads, however, pneumatic technology is cleaner, used for lighter loads (such as office chairs), and is both safer and easier to store. Both systems use the same technology, however, pneumatics are generally used for office chairs.<\/p>\n

How does a pneumatic system work?<\/strong><\/h2>\n

Pneumatic chairs are adjustable using a lever generally situated just below the seat. This lever moves the seat up and down in a fluid motion. But how does this work? There are quite a few components that are incorporated into a pneumatic chair! They are:<\/p>\n
