Slow news week, huh. I sit up because its easier to breathe that way. I have asthma and straightening my posture helps me focus long-term. It's so simple.

Also, if you've ever had back pain at a desk job then you probably know the value of lumbar support. Sitting hunched over or fully reclined is just not a feasible way to sit for 5-7 hours a day, 5 days a week.
