This purchase was made to use in an office setting where I am at my desk for long periods of time. This chair provides good support and I am very happy with it.
I bought this chair about 3 months ago and found it very comfortable for a while despite the armrests not having enough downward travel. 3 months in and now the mesh in the seat has loosened up to the point there is very little support. I'm 5'11" and 165 lbs so this is not something I would've expected. I've recently added a memory foam seat cushion which helps tremendously. I just wish I had gone with a higher quality foam-seated chair to begin with. On the plus side the 2" memory foam seat cushion has improved the arm travel issue significantly.
This chair is a huge upgrade from my old one. Only have had it for a week but I am very pleased with it. I am able to sit in it for hours at a time comfortably. I picked mine up for $180 when it was on sale you can't beat the quality for that price.
