Good ergonomic chairs are certified by government health and safety inspection service in our country to prevent ilness and injuries to workers and come with certifications like NPR 1813 and NEN 1335. My ergonomic chairs are fully adjustable to NEN 1335 specifications. I would not buy any office chair without these certifications.
