The worst part is that you can’t adjust the lumbar support, which will definitely lead to increased back pain. Rosi Incorporated, an office system provider in the United States says, “annual losses of over $81 billion dollars are being reported just due to pain. That’s a staggering amount considering much of that could be prevented by re-examining your office ergonomics. Using poorly designed office chairs causes stress to the whole body, as you have to constantly compensate for lack of support.” Converted, that’s about R10 billion lost each year!http://www.byouzhun.com/office-chair/
