I have been trying to break some of my bad habits - one of which is slouching. I have back problems and I find myself slouching at my desk to relieve the pain. I always try to have everything ergonomically correct at my desk - make sure that my legs are at a 90 degree angle, my arms are desk height, the monitor is in the correct position, etc. But still I would find myself slouching a lot.
We have had the Zenergy chair in our showroom for quite some time now (we call it the mushroom chair) and when I first saw it, I wasn't interested at all, but then a medical professional suggested that a ball chair would help my back. Since we are a working showroom, I replaced my desk chair with this one to try it out.
