“I recently acquired a CT-580 Mesh Back Executive chair and it is the most comfortable office chair that I have ever owned. It has all of the ergonomics of any other premium office chair, but with the added benefit of the special back-saving feature in the seat.
I am a general contractor who has endured lower back pain for many years. After several hours of sitting in my office or my truck, I usually have momentary, but severe, back pain immediately upon standing. However, I can sit in this chair for hours with little or no pain when I stand. It has made all of the difference in the world to me and I highly recommend this chair to anyone else who has had similar issues.
