We bought 4 of these in our office. All 4 of us like it very much. The mesh back and seat conform to your body but are very supportive (like a good quality mattress) so they are comfortable all day long. I don't experience the fatigue I did with my old chair at the office. The adjustments are easy and simple. The wheel base is wide so the chair is stable ... would be hard to tip over in it. It's not an executive luxury leather chair that screams "CEO" in it's styling but as a task chair it's amazing. So ... I bought one for myself for my home office during this COVID19 crisis. Assembly is also very easy. One of the chairs at the office had the mesh netting come away from the frame ... the replacement was simple no questions asked ... within warranty no additional warranty purchased.
Chair was easy to assemble and very comfortable. Seems surprisingly durable despite the mesh looking a little fragile. Fine now in cool spring should also be comfortable on hot summer days.
I'm a 5'10" thin female. Bought this as a "go-between" my old ancient chair until I can afford the "cadillac." I've only used it a month but it seems just fine. I will sit at my desk for HOURS at a time and ... fatigue is fatigue but I'll keep this one for the time being. Of course it could have a few more adjustment controls but that's why THOSE chairs cost the big bucks.
