Chair is not very comfortable. For short periods of sitting it is fine. But if you work in an office and sit most of the day this is not the chair for you.
This chair is very comfortable supportive and adjustable. I can stay in it all day. My only negative comment is that I am working from home and wearing shorts every day and the mesh seat is not very comfortable on bare skin.
Chair is made of good quality material. Mesh is stiff lumbar support is good. Next support is lacking adjustment. Although it is a nice ergonomic chair otherwise I felt that it would have been even better if the base was a little bigger.
