This chair broke in the second day lumbar support is terrible and the plastic broke on the second day of use. One of the arms would not tighten up. The retaining bolts are threaded into plastic when it should be metal. For the price this chair is terrible. I sent it back.
The mesh is the best part of the chair. Excellent breathability and I don't really sweat using it. Everything else is horrible. I am 5'7". I was told this chair is good for those of shorter stature or average height. Too bad its actually the worst chair I've ever owned. I can't make the chair backrest move forward and make it straight enough my back is always at a tilt and its extremely uncomfortable. The lumbar support is useless. If I adjust it upwards to my comfort spot it just falls down and adjusts to the default position after 30 mins of sitting. The neckrest is ppositioned too high and useless. Keeping it installed pushes my head WAYYY too forward causing me to sit like the hunchback of notre dam. It is painful and uncomofrtable. The backrest is too wide. For gaming I can't move my mouse arm backwards because it blocks my triceps while also keeping my back supported on it I want to return and get a refund if possible. This chair is HORRIBLE.
I did a lot of research on computer chairs and kept coming back to this one. I am glad I did this thing feels great. I am ordering a second one for my home office.
