This desk chair is more rigid than my prior chair. I don't feel like I'm going to fall over backward if I lean back - rows nicely. All things considered however it is a chair.
The chair seat is comfortable. What I don't find very comfortable are the arms. There is an indention for your arm to rest which is fine if your arm is aligned with the arm itself. I however find that when my arms are sideways to the arms of the chair it is uncomfortable. My husband also has a Staples office chair but the arms on his chair are flat with no indentions.
