I read a lot of trouble to many ergonomic seats and it is not very expensive, I do not expect something exceptional. Well, that surprises me by its seat comfort and robustness. The metal structure that it does not creak and not deformed. The wheels are solid enough and does not come out of their axis with every movement a little faster. The foam cushions also keeps its promises (see after a year or two). Anyway, I thought I would use this seat from time to time, and relief of the lumbar and shoulders is such that my old leather chair, sweatshirt and flip remains stored deep in my office. I can spend hours in front of my screen or office without having the impression of hunched and drooping shoulders. Be careful, the first weeks, prolonged sitting on stations such office ended up sore legs and knees. It takes a little practice to use it exclusively full time. But I would not change it for the world.
