How much sport do you do for your back? This setup looks like it's comfortable, but not healthy. I'm not a physician but a friend of mine is, he said this is not a good idea, you need to move your back etc to give nutrition to your spinal discs. I'm using a Swopper as chair, it's quite nice and allows me to move around all day, but it also requires discipline and a bit of back training.
