My Ergo 3D is an awesome chair!! Was experiencing lower back pain that steadily grew worse since working from home at end of April. This is much more comfortable, and lower back is getting better! 

Customer service team is very responsive to my questions!

Chair arrived in very high quality packaging - demonstrating to me that Nouhaus is committed to quality at every step of the buying process.

Now, my son wants one, and am ordering a second Ergo 3D chair.

Many thanks, Nouhaus!
