Do you have low back pain? Fancy chair manufacturers would like you to believe their chairs can solve all of your problems using “Zero Gravity” technology. Believe me, I have sat in some of these chairs and they are extremely comfortable. However, as soon as I took my first test drive in one I realized why – a zero gravity chair reclines you into the 90/90 position! By using tiny sensors placed into the intervertebral discs of the spine, researchers have found that the 90/90 position places the least amount of pressure on your discs, which are a major source of low back pain. What is the 90/90 position? As demonstrated in both of the pictures below, it is assumed by lying on your back with your hips and your knees flexed to 90 degrees. That’s it. It’s that simple. I recommend it to all of my low back pain patients. And, despite what fancy chair salesmen might tell you, you don’t need a special chair to feel the relief of the 90/90 position.
