This chair is very good my posture. I can pull up close to the desk and I am forced to sit correctly. Since it has a mesh back/bottom it allows me to stay cool.
The chair is comfortable and supportive but the back can lock only in the fully upright position and I sometimes like a bit of a recline without having to constantly push against the chair's back spring.
This chair was exactly what I was looking for great quality easy to set up took less than 30 minutes. Within the first day I noticed a difference in the way I was sitting - straight which helped with back problems I was having with my previous chair. Sturdy breathable and the back support which is nice. I am about 5’9” so the head support is the perfect height for me but I understand if someone was taller it would be more of an issue. Love my purchase and so does my back at the end of the day!
I like the mesh lumbar and neck support. Arms are adjustable up/down. Seat height adjustable. 5 stars for the price. Ideally i would like arms that can be adjusted closer to the body but that would be a more expensive chair.
