Assembly required only a screwdriver; took 5 minutes. Had a "rocker" style kneeling chair in the 90's, but this version w/wheels is more convenient. I'm 5'9". The chair fits me fine, but am not sure how well it would work for taller people or those with longer legs. Would recommend trying before buying, if you can find one to try, and would test it over at least 2-3 hours, as just sitting on one for a minute or two may not reveal how it will really fit you. Many people buy these to help with back pain. I use it to alleviate leg pain from sitting in normal chairs and car seats. Works well for this.
