The word "ergonomic" originated from the Greek words "ergos" meaning work, and "nomos," meaning natural laws of. In essence ergonomics is the study of how we can manipulate our work environment to better suit our bodies while we work. Humans were not designed to sit for 8 plus hours a day! Knowing this ergonomists have spent decades studying how to better support the body during this unnatural process of seated task work.
There are many aspects involved in creating a functional, ergonomic work environment. There are so many we cannot cover all of them in one article so we'll focus on the the most important piece of ergonomic furniture in your office. YOUR CHAIR. There is only one piece of ergonomic furniture you will always be in contact with and that is your ergonomic chair. Whenever your sitting at your desk your body is in constant contact with whatever form of office seating you've chosen to use. It's important that the seat and back surfaces are constructed with materials that reduce pressure points and follows the contours of the body. "Continuous Support" is the foundation of every ergonomic office chair.
For years manufacturers focused on using multiple layers of foam with different densities. In 1994 Herman Miller introduced the Aeron Chair using mesh for both the seat and the back. The use of mesh was genius and sparked a revolution in the design and manufacture of office seating. The introduction of mesh to the seat and back yields perfection in continuous support. The mesh follows every curve of the body and cradles the user. The lumbar area of the back is of particular advantage because each users body is of different proportions. The mesh gives in the scapular areas and remains tight in the lumbar region which improves posture immensely. This can be achieved with a foam chair but the chair would not be perfect for every user. A chair with mesh on the seat or back can be used by a wider range of body types and can provide continuous support to all of them!
Ergonomic mesh chairs are not only look cool but as you can see they have functional purpose as well. A mesh office chairs ability to provide ergonomically correct support to the users is unsurpassed by any other material. There are now many manufacturers providing chairs with mesh used to upholster the seating surfaces. Chairs with mesh seats are generally more expensive because they're more complex and expensive to manufacture. Many office chairs have mesh backs only and a traditional foam seat. This makes for a more affordable ergonomic mesh chair. Either option is generally better than a traditional office chair with foam cushions because of the properties of mesh upholstery.
