The chair is comfortable and I like the blue color. I normally get one with padding in the back due to back issues but this one (without any padding in the back) is just fine. Rolls fine.
I find this chair not very comfortable for me. The chair back design does not permit sitting clear to the back of the seat cushion. The seat padding is not sufficient and will probably not last long term. I am average build 5' 10" 175 lbs
The chair is surprisingly comfortable and though I wouldn't say it's ergonomic it's certainly comfortable enough for me to sit in for several hours (I do have a bolster cushion as well). For the price point quality isn't bad though of course with any chair that is mostly plastic I don't expect this to be a chair that will last me many years. It wasn't too hard to assemble and having another person help hold things still made things easier. Rolls smoothly mesh is not scratchy and arms are a reasonable height. I did not find the seat to be too narrow and I am able to sit cross legged on the chair.
