I've be using my Nouhaus for 6-8 hours, 5 days a week for 6 weeks now. It has made a huge difference at the end of my work day — I would end the day with a sore back, but no more! The chair seems like it would be adjustable to most needs and preferences — I had a day of adjustment when switching to a higher desk, but otherwise had no problem. I think this chair is worth the price!
