We have Mirra Chairs at work. These chairs won out over the better known Aeron Chairs after we tested both for a week, courtesy of a local dealer. Last week, since I was experiencing some shoulder tension after work, I searched to make sure that I had everything properly adjusted, and found a web-site supporting something I had long suspected: there are pros and cons to all ergonomic products. I ended up trying to follow the tips in “How to Keep Good Posture When In Front of a Computer at Ririan Project” and also found “Rethinking ergonomic sitting and seating ergonomics” interesting.
The net result seems to be that sitting for long periods of time is bad for the body, and taking frequent breaks is a necessity. And something I am doing is helping: I haven’t noticed the shoulder tension in the evenings the past few days.
