Office Chairs, Seatbacks, Ergonomics And Lumbar Support And Why They All Work
Office Chairs don’t really require a seatback in order to work properly. The spine is able to maintain it’s natural curvature even without the lower back support provided by the average task chair seatback. However, the natural tendency for most people when seated for long periods of time in front of the computer is to slouch forward towards what they are concentrating on.
This slouching posture pushes out the lower back, making the natural inward curve point in the wrong direction. With the spine pushing outward towards the chair, the lower back structure is strained, creating unneeded tension. It was obvious there was a need to remind all of us to sit properly and the lower back supports for seatbacks on office chairs were born.
