Re:Swiss Ball! (Score 1)

Having tried the Varier Balans, I must say that I preferred to use Multi Balans. The Multi-version is fixed and even though it adds pressure to your knees, it allows you to switch between two to three different angles in order to move the pressurepoint. With the chair itself fixed you can sit in different ways (one foot to the side, or on the kneerest) without loosing balance. Now that you got me to look at chairs from Varier I can't help but to think that the Gravity-model, with a solid notebook-holding mechanism would be cool. There is a lot of chairs that allows you to tilt, but I haven't found one that is designed to let you work with notebook.
