ERGONOMIC SHAPES: CHAIRS

What is ergonomics?
click here

Most people have heard of ergonomics and think it is something to do with seating or with the design of car controls and instruments. It is...but it is much more! Ergonomics is the application of scientific information concerning humans to the design of objects, systems and environment for human use. Ergonomics comes into everything which involves people. Work systems, sports and leisure, health and safety should all embody ergonomics principles if well designed.

Most of us spend at least half the day sitting. We sit in cars, trains and buses on the way to work. During work, we sit most of the day performing computer-intense work or participating in meetings. At the end of the day we sit at home eating meals, engaged in conversation, reading a book, or watching TV. Currently, in our information-based society, half of all workers are sitting in offices and this number continues to grow.

As we have become a society that sits for a greater percentage of the day has made the office chair a critical component in determining our overall comfort and health. The chair must not only support the body but also must support it as it changes position.

For the workplace, Industrial Designers design chairs to comfortably accommodate workers of many different sizes, preventing the need to continuously lean or overextend the arms. Ergonomically designed chairs distribute a person's body weight evenly to avoid back and neck strain. These chairs adjust to a user's height to ensure that the feet rest flat on the ground.

An organisation, campaign for better seating, brings information about the importance of chair design to the attention of everyone who needs to know: the public, furniture designers, those responsible for seating in public places.
They warn that
MANY MODERN SEATS ARE A PUBLIC HEALTH HAZARD!

Although more attention is paid to design and ergonomics than ever before, the combination of shapes based on new technologies, and confusion about natural posture, has resulted in new, experimental seats which have not been used and tested over long periods of time. Yet, these new seats are everywhere, in the home, in public transport, in public buildings. And these seats are contributing to the problem of poor posture and back trouble.

What should you look for in a seat?
