Excellent material and comfortable for long periods of sitting. The material is also highly breathable so you won't get sweaty. Was easy to put together. The chair is big enough to not constrain you but takes up a small amount of room surprisingly.
Super supportive back rest and the mesh seat lets your butt breath yet is very comfortable. I first used this chair at my current job and liked it so much I bought one for my home office.
Hard to beat value - comfortable with good functionality and very practical design modern looking yet not intrusive or pompous... really happy so far. Easy to install too.
