It is very comfortable. I am a big woman and I am able to sit all day in it without issues. This is the third chair I bought in the last 5 months. Wish it was the first.
The Mesh seat started coming off of its frame on the right side by the arm_rest just after one week of use. The chair was assembled by the store employee before he placed it in my car. I am a male (weighing 210 pounds) using this chair for my home office. The seat is not comfortable for longer sittings as it only supports a part of user's seat.
We have purchased 5 of these chairs and absolutely love them! The are easy to put together and comfortable to sit in for 8 hours. Good back support as well!
The chair was very easy to put together and very comfortable. I do wish it sat straight up there is a tilt to the backside which I'm sure is what makes it ergonomically correct. Thank goodness I also purchased a foot rest so it is makes up for not being able to sit straight up like I prefer.
