The chair has a very comfortable seat. I can sit for several hours without back pain or stiffness. The chair has adjustability of height seat pan angle and back rest angle. It is easy to get it in just the right position for each user.
That is why I bought it as you can adjust it everywhere. The problem is I have arthritis from the top of my neck down to my tail bone. I was sincerely hoping this would be the chair that would be comfortable enough but unfortunately it was not. I had to return it. That being said This chair is amazing for a person without my ailments as you can adjust the arm height the height of the chair itself the angle of the chair and the lumbar support. It is extremely well made as well--just not for my needs
Our office needed some new ergonomic chairs. We tried this one out in the store and found it to be comfortable and highly adjustable. We bought ten of them. Even better they were on sale for $100 each (regular price is $150). Assembly time is about five minutes.
The setup manual is easy to follow. The settings of the chair are highly adjustable. It's not an overwhelmingly huge monster like some other chairs are. My fav is the back vertical adjustment much smarter and easier than previous chairs I've owned.
For the most part this chair is really comfortable. It seems like the cushion needs to be a little better quality not cushy enough. I love the lumbar support and the mesh backing because it keeps my back from getting hot and I get great support. I needed a chair without arms and I was able to assemble this without attaching the arm rests which was awesome. The ability to adjust the chair several different ways I great as well. I use my chair quite a bit as I work from home and if I start getting uncomfortable I can readjust it and it really helps with my comfort level.
