When we are sitting without proper back support we have up to 3 times more strain on the lower back then we do when we are standing. The human body was not originally designed to sit for long period of time that modern humans tend to, and in addition to lower back pain, inadequate support also puts stress on joints & surrounding tissues. Many people compensate by shifting more of their weight forward while sitting, but this can create additional pain and may also trigger sciatica.
Hence the lumbar support becomes the most essential element of chair design. This one corrective will go a long way to easing any lower back pain and will also help alleviate any secondary pain in your neck & leg.
