Love my chair!

I don't usually write reviews but I felt compelled. I am a runner but I am plagued by psoas joint pain - which is sharp pain in the hip area. The pain is increased by sitting for very long. I've had my chair for about 4 weeks now. I absolutely love the chair! Now just to be clear, the first week to 2 weeks it was an adjustment. My back muscles were sore as I made the adjustment to my posture. Now my posture is 100% better than how I used to have to sit dealing with the hip pain. And I am pretty much pain free sitting in this chair. I would give this chair 100 stars if I could!
